“…[16][17][18][19][20] Pharmaceuticals are expected to be susceptible to direct photodegradation, where the direct absorption of photons leads to degradation of pollutants or indirect photolysis, which occurs in the presence of photosensitisers. 21,22 In addition, researchers have shown that reactive oxygen species (ROS) including singlet oxygen ( 1 O 2 ) and even stronger oxidant hydroxyl radical ($OH) can be photogenerated by certain drugs to subsequently oxidize and degrade the pollutants, which is designated as the selfsensitized photodegradation of pollutants.…”

a Clofibric acid is one of the most frequently detected pharmaceuticals in various aquatic environments.Photodegradation of clofibric acid in water under simulated sunlight was investigated. The effects of different initial concentrations, pH conditions and dissolved oxygen were examined. Photodegradation of clofibric acid followed a pseudo-first-order kinetics model, and the rate decreased gradually with the increasing initial concentration of clofibric acid. Dissolved oxygen inhibited the photodegradation of clofibric acid. As a result of varying reaction species of clofibric acid, the initial pH conditions greatly influenced its photodegradation. Quenching experiments showed that the self-sensitization process via $OH and

“…In a recent work, g-C 3 N 4 /MIL-153(Fe) was successfully prepared, demonstrating high conversion rates for the reduction of Cr(VI). The study revealed that the activity was not only favored by the inhibition of recombination but also because the contact improved charges mobility thanks to the good conductive properties of g-C 3 N 4 [231]. Analogous performance was obtained when MIL-53(Fe) was assembled with reduced graphene oxide (rGO), which was able to minimize the charges recombination [232].…”

This review analyzes the preparation and characterization of metal organic frameworks (MOFs) and their application as photocatalysts for water purification. The study begins by highlighting the problem of water scarcity and the different solutions for purification, including photocatalysis with semiconductors, such as MOFs. It also describes the different methodologies that can be used for the synthesis of MOFs, paying attention to the purification and activation steps. The characterization of MOFs and the different approaches that can be followed to learn the photocatalytic processes are also detailed. Finally, the work reviews literature focused on the degradation of contaminants from water using MOF-based photocatalysts under light irradiation.

“…Although some materials have limited practical applications of CO 2 absorption-reduction directly at the source point of power plants due to their susceptibility to harsh conditions (e.g., acidity, alkalinity, heat, humidity), they are categorized as cost-effective with potent CO 2 absorption and elimination ability [86,87]. Moreover, this material could be packed at the nanoscale to be deployed for atmospheric CO 2 trapping and conversion to retrieve the environment being [88][89][90][91][92].…”

Recent Innovation of Metal-Organic Frameworks for Carbon Dioxide Photocatalytic Reduction

The accumulation of carbon dioxide (CO2) pollutants in the atmosphere begets global warming, forcing us to face tangible catastrophes worldwide. Environmental affability, affordability, and efficient CO2 metamorphotic capacity are critical factors for photocatalysts; metal-organic frameworks (MOFs) are one of the best candidates. MOFs, as hybrid organic ligand and inorganic nodal metal with tailorable morphological texture and adaptable electronic structure, are contemporary artificial photocatalysts. The semiconducting nature and porous topology of MOFs, respectively, assists with photogenerated multi-exciton injection and adsorption of substrate proximate to void cavities, thereby converting CO2. The vitality of the employment of MOFs in CO2 photolytic reaction has emerged from the fact that they are not only an inherently eco-friendly weapon for pollutant extermination, but also a potential tool for alleviating foreseeable fuel crises. The excellent synergistic interaction between the central metal and organic linker allows decisive implementation for the design, integration, and application of the catalytic bundle. In this review, we presented recent MOF headway focusing on reports of the last three years, exhaustively categorized based on central metal-type, and novel discussion, from material preparation to photocatalytic, simulated performance recordings of respective as-synthesized materials. The selective CO2 reduction capacities into syngas or formate of standalone or composite MOFs with definite photocatalytic reaction conditions was considered and compared.
