This study investigates the use of UV light to enhance the degradation of organic contaminants in wastewater by photocatalysis.

Two particular MOFs, ZIF-8 and MIL-53 (Al), were synthetized through a distinctive electrochemical method. Unlike the ZIF-8, the electrochemical method for synthesizing MIL-53(Al) encounters a significant obstacle. In this case, the issue was tackled using a self-synthesized ionic liquid (1-Dodecyl-3-methylimidazolium chloride) as the electrolyte, resulting in the creation of a MIL-53(Al) structure similar to the one obtained through solvothermal synthesis. A comprehensive parametric analysis was performed, taking into account the influence of different factors such as solvent composition, reaction time, cell voltage, electrode surface area/cell volume ratio, and cell temperature on both cell efficiency and CO₂ adsorption capability. Different techniques were used for characterizing both samples to determine their physicochemical properties including X-ray diffraction, BET analysis, FTIR, TGA, and SEM. The parametric analysis demonstrated that the key synthesis parameters influencing CO₂ adsorption capacity were cell voltage, cell temperature, and the electrode surface area/cell volume ratio. The findings also showed that the highest CO₂ absorption of 6.07 mmol/g was obtained from the ZIF-8 produced under the optimized conditions, while the maximum quantity of CO₂ captured by the optimized MIL-53(Al) sample was 3.89 mmol/g in the identical electrochemical cell.

The adsorption process was mainly driven by the electrostatic interaction, complexation and partial ion exchange following the chemical reduction of Cr(VI) to Cr(III). The excellent adsorption performance of HBSPM is attributed to the hydrothermal treatment resulting in an increase of the number of oxygen-containing functional groups on the membrane surface, which further enhance their bonding effect with Cr(VI).
