Enhancement of photocatalytic dye degradation efficiency of ZnO/Ag film deposited on flexible stainless steel meshes through g-C₃N₄ addition

Microwave-Assisted Catalytic Degradation of Brilliant Green by Spinel Zinc Ferrite Sheets

“…Ultraviolet light sources are better in that sense, and photon energy is relatively higher, and therefore, even without much effort, one can in principle get better beam energy and hence improved catalytic efficiency. 41−45 MW energy is highly tunable in a controlled manner with extremely high precision by externally controlled MW power. That is the reason that in recent years, it has been employed in catalysis and still is an emerging technology as far as catalysis is concerned.…”

“…However, because photon energy ( hc /λ) is less and that is why even after focusing, it is difficult to attain high beam energy. Ultraviolet light sources are better in that sense, and photon energy is relatively higher, and therefore, even without much effort, one can in principle get better beam energy and hence improved catalytic efficiency. − MW energy is highly tunable in a controlled manner with extremely high precision by externally controlled MW power. That is the reason that in recent years, it has been employed in catalysis and still is an emerging technology as far as catalysis is concerned. − However, the choice of catalysts (which efficiently responds to MW) and catalyst–organic dye interaction is of essence (chemisorption is desirable though) and these have to be suitably and adequately be satisfied so as to attain higher efficiency.…”

Photocatalytic Membranes Toward Practical Environmental Remediation: Fundamental, Fabrication, and Application

“…In addition to the above traditional fibers, stainless steel, carbon nanofibers, and carbon cloth with high conductivity are also substrates with good performance. [43,44] To ensure the effectiveness of photocatalytic membranes in practical applications, the design requirements are as follow: 1) Both the photocatalyst and the substrate must be working stably for a long time, and the photocatalytic membranes have high mechanical strength and are not easy to be destroyed by aquatic creatures such as fish. 2) Photocatalysts will not fall off from photocatalytic membranes, causing secondary pollution.…”
