In the photocatalysis process, photon energy is mainly converted into chem. energy with the help of both light and catalyst. This process can be used in different applications like photocatalytic degradation of hazardous compounds, fixation of nitrogen, hydrogen production, air purification, water splitting, carbon dioxide reduction etc. In this research work, multiplicative ZnO and MoS2/ZnO (MZ) composites were synthesized using green chem. methods like the hydrothermal process and used in two different applications i) photocatalytic degradation of ciprofloxacin (CIP) antibiotic and ii) hydrogen production CIP is not easily biodegradable and is mainly used in various antibacterial treatments. The photocatalytic activity was tested for ZnO and different MoS2/ZnO composites along with this the effect of different amounts of catalysts doses was studied. MoS2/ZnO composites exhibit superior photocatalytic performance than ZnO for photocatalytic degradation of CIP. Using the LC-MS technique possible degradation pathways are proposed. The same photocatalyst materials were used to test the photocatalytic H2 production activity. H2 production rates were found to be 22, 39 and 235 μmol/g/h for ZnO, MoS2 and MZ-30 composite resp. Superior photocatalytic activity of MZ-30 composite than ZnO is chiefly attributed to the extended light absorption capacity, effective charge transfer, suitable band alignment between the ZnO and MoS2, min. recombination of charge carriers etc. In the experiment, the researchers used many compounds, for example, 1-Cyclopropyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 85721-33-1Formula: C17H18FN3O3).
1-Cyclopropyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 85721-33-1) belongs to piperazine derivatives. The piperazine scaffold is often found in biologically active compounds in different therapeutic areas. These therapeutic areas include antifungals, antidepressants, antivirals, and serotonin receptor (5-HT) antagonists/agonists. Intermediate for a wide range of pharmaceuticals, polymers, dyes, corrosion inhibitors, rubber accelerators and surfactants.Formula: C17H18FN3O3
