Prasetya N, Li K, 2022, Synthesis of defective MOF-801 via an environmentally benign approach for diclofenac removal from water streams, Separation and Purification Technology, Vol: 301, Pages: 1-12, ISSN: 1383-5866

Diclofenac is one of the most popular non-steroidal anti-inflammatory drugs (NSAIDs) which has been widely used worldwide. Despite its popularity, its accumulation in the environment poses danger to the aquatic lives and its removal from the environment is paramount important. Although some conventional adsorbents such as activated carbon can be readily used to address this issue, they usually suffer from low diclofenac adsorption capacity (around 200 mg g−1), resulting in bulky adsorption systems. To overcome this problem, high performance materials such as metal organic frameworks (MOFs) can be employed. Here, we report that we synthesised defective MOF-801 for enhanced diclofenac adsorption via a simple and environmentally benign approach. Differing from a conventional MOF synthesis that usually requires the use of organic solvents at high temperature, the defective MOF-801 could be synthesised at room temperature and by changing the reaction medium from dimethylformamide to water. In addition, we have also successfully shown in this study that the defect concentration in MOF-801 can be rationally tuned by adjusting the modulator concentration (formic acid) in the synthesis solution. The resulting defective MOF-801 can then be used for environmental remediation, which we have shown here by employing them as an adsorbent for diclofenac removal from water streams. The enhanced adsorption of defective MOF-801 in comparison to its non-defective counterpart is due to the pore enlargement of the defective MOF-801 which provides a better pathway to access the adsorption sites. The maximum diclofenac adsorption capacity in a highly defective MOF-801 can reach as high as 680 mg g−1, which is almost 4 times higher than its non-defective counterpart. This study then opens possibilities to engineer the MOF particles for environmental remediation.

Wu T, Prasetya N, Li K, 2022, Re-generable and re-synthesisable micro-structured MIL-53 Rachig Rings for ibuprofen removal, Journal of Environmental Chemical Engineering, Vol: 10, Pages: 107432-107432, ISSN: 2213-3437

Water-stable metal–organic frameworks (MOFs) are attractive adsorbent materials for water purification. However, for practical applications, they must be structured into beads, granules, pellets, etc. which would impair their adsorption performances. This study demonstrates the feasibility in developing a water-stable MIL-53 onto a micro-structured alumina Raschig Ring (Al-RR) served not only as an aluminium metal source, but also as a support. Our results showed that a MIL-53 layer covers the entire surface of the Al-RR. The unique structure of the Al-RR allows easy access of water pollutants, hence achieving high adsorption efficiencies with its estimated equilibrium adsorption capacity between 222 and 300 mg g−1. In addition, the synthesised MIL-53 Raschig Ring (MIL-53-RR) can be regenerated or re-synthesised without any significant reduction in the adsorption performances, indicating the potential for possible commercialisation of the MIL-53-RR for water purifications such as ibuprofen removal from water.

Ceramic membranes have shown great potential and versatility in a number of industrial and commercial sectors, aside from an expanding field among research communities. The distinctive feature of superior chemical, mechanical and thermal stability leads to its significance in separation processes, particularly under harsh conditions. In addition, ceramic membranes made from specific materials can theoretically display infinite permselectivity for certain gases, a property that offers great potential for industrial gas separation with improved purity. Such membranes, whose working principles depend on ionic conduction at elevated temperatures, also serve as the core component for membrane reactors or ceramic fuel cells for important energy applications. This chapter includes a general introduction to ceramic membranes, working principles, and the latest membrane design for oxygen permeation membrane (OPM) as well as OPM-based ceramic fuel cells for clean and sustainable energy generation.

The combined crystallisation and diffusion method (CCD) has recently demonstrated its superiority in producing high-performance PVDF membranes over the traditional membrane preparation methods. The CCD method involves a unidirectional cooling step in its membrane preparation. While the role of kinetics behind the CCD method has been thoroughly studied by varying the cooling rate, the cooling temperature itself has never been changed from −30 °C. This study therefore explores the thermodynamic implications of changing the cooling temperature during the CCD process on the morphology and performance of the resultant membranes. Two different molecular weights of PVDF were studied and different batches of membranes were prepared by progressively changing the cooling temperature from −30 °C to 0 °C. The results showed that for both the PVDF types, with an increase in cooling temperature, the separation surface pore sizes and membrane permeances increase but more so for the one prepared using the higher molecular weight PVDF. This showcases the ability to tailor the properties of the CCD membranes by merely changing the cooling temperature. The membranes were then also characterised for their morphology, mechanical strengths and crystallinity to help further understand the role of cooling temperature in affecting these membrane properties.

Prasetya N, Li K, 2021, MOF-808 and its hollow fibre adsorbents for efficient diclofenac removal, Chemical Engineering Journal, Vol: 417, Pages: 1-11, ISSN: 1385-8947

The popularity of diclofenac, one of the highly effective non-steroidal anti-inflammatory drugs (NSAIDs), has led to its excessive consumptions. Consequently, its presence in water bodies is continually increasing and poses serious threats to ecosystems. Adsorption processes have been employed to address this issue. However, most of the commercially available adsorbents such as activated carbon, zeolite, etc. suffer from relatively low diclofenac adsorption capacity (100-200 mg g-1) and slow kinetics. Herein, we explore the potential of MOF-808 as a superior adsorbent for diclofenac removal. Benefitting from its high specific surface area and large pore aperture, the maximum diclofenac adsorption capacity achieved in this study reaches 833 mg g-1 with almost 95% removal within first hour. This performance is one of the highest reported adsorbents for diclofenac removal so far and has led us to have further commercial exploitation by employing a yttria-stabilised zirconia (YSZ) hollow fibre support where the MOF-808 adsorbent is deposited on its outer surface. Such a configuration is beneficial from a practical point-of-view, as it eliminates the requirement of separation of powdered adsorbents from treated water once the adsorption process finishes. Also, the hollow fibre configuration not only substantially increases the surface-area-to-volume ratio of adsorption systems, but also reduces the maldistribution of flows commonly unavoidable in conventional packed bed adsorption columns. The high-efficiency of the MOF-808 hollow fibre adsorbent is exhibited by retainment of its equilibrium adsorption capacity of 796 mg g-1. More importantly, the MOF-808 hollow fibre adsorbent can withstand at least 4 adsorption-regeneration cycles without any significant reduction in the adsorption performances, indicating the potential for possible commercialisation of the MOF-808 adsorbent for diclofenac removal from water.

Aluminium-based metal organic frameworks (MOFs) are considered as one of the most promising MOFs which have been widely investigated because of their excellent framework stability. In addition, aluminium is a relatively cheap and abundant metal source compared to others, making it as an attractive metal source for mass production of the MOFs. Because of some promising properties of the aluminium-based MOFs, they have also been fabricated to membranes for advanced molecular separations. This article intends to give a comprehensive review starting from the state-of-the-art of general MOF materials with specific emphasis on aluminium-based MOFs, followed by the membranes and its applications in fluid separation. The most-promising and well-studied aluminium MOFs families from MIL (Materials Institute Lavoisier) and CAU (Christian-Albrechts-University) class are first reviewed. The discussion includes their basic properties and some examples of applications. This is then followed by discussions on the common and novel strategies to turn them into membranes with various pathways. Afterwards, various applications of aluminium-based MOF membranes are discussed. Finally, the outlook both from the MOF and membranes perspectives is also discussed which could aid to direct the future research in this field.
