Summary: This article mainly introduces the application of metal-organic frameworks (MOFs) materials in water treatment, and discusses the combining methods of MOFs and hydrogels and their pros and cons. Meanwhile, the performance of MOF/hydrogel composites in removing metal ions, organic dyes, and drug residue molecules is reviewed, and the structure-performance relationship of MOF/hydrogels synthesized via different routes is analyzed. Finally, challenges and outlooks regarding the green synthesis, stability, and computational design of MOF/hydrogel composites are briefly discussed.

Summary: Persistent organic pollutants (POPs) are highly toxic to aquatic and human life and need to be removed from wastewater before discharge. Biochar (BC) based metal composites have been widely used in advanced technologies to degrade POPs, but raw BC has certain limitations that require modification. This state-of-the-art review discusses the application of BC-based advanced technologies and their basic mechanisms for POPs remediation, as well as the associated risks, synthesis procedures, and reusability of BC. The bottlenecks for real-life applications and commercialization of BC-based catalysts in advanced technologies are also highlighted.

Summary: Nonthermal plasma (NTP) is an efficient, mild, and environmentally friendly technology that has been used to degrade volatile organic compounds (VOCs) in the atmosphere and wastewater. This review summarizes the principles of NTP production, the applications of NTP in VOC removal using different types of reactors, and the use of NTP combined with catalysts/oxidants to enhance energy efficiency. The effects of various important factors on VOC degradation performance are explained, and the reactive species generated in NTP discharge process and their roles in decomposing VOC molecules are discussed.

Summary: This article reviews studies on the solubility and stability of organic compounds in subcritical water conducted over the past 25 years. The understanding of organic compound solubility and decomposition in this green solvent is crucial in various fields including environmental remediation, chemistry, chemical engineering, medicine, polymer, food, and agriculture. The article summarizes and discusses the experimental systems, mathematical equations, and correlation between predicted and experimental data used in solubility studies. It also provides an overview of organic decomposition under subcritical water conditions with the findings that solubility and decomposition increase with temperature.

Summary: Ammonia is a promising energy and hydrogen carrier, but its utilization for hydrogen delivery or direct power generation is still under development. This study investigates the development status and potential cost of plasma and electrolysis-based ammonia decomposition and compares them with thermalchemical decomposition and direct ammonia-to-power solid oxide fuel cell systems. The results suggest that plasma-based decomposition needs significant improvement in energy efficiency, while electrolysis decomposition requires enhanced durability using inexpensive electrolytes, to achieve cost parity with cracking technologies.

Summary: This study investigated the adsorption potential of activated carbon as a drinking water treatment option for persistent and mobile (PM) substances. The results showed that the adsorption of PM candidates was highly variable and not directly related to molecular properties. Only five out of the 19 substances tested were readily removed, while five others showed negligible removal. Surrogate correlations between removals and UVA254 abatements were established to estimate PM candidate elimination.

Summary: The increased applications of fluorochemicals have led to the development of elemental methods for their detection and quantitation. A new approach using post-ICP chemical ionization has been introduced to enhance analytical performance for fluorine detection in liquid samples. This method demonstrated significantly improved sensitivities and lower detection limits compared to conventional ICP-MS methods.
