The coupled CuO-SnO2 catalyst: Characterization and the photodegradation kinetics towards phenazopyridine

One-pot in situ synthesis of an NS-ligand co-doped metal–organic framework for the enhanced adsorption-assisted photocatalytic decontamination of metronidazole

“…Heterogeneous photocatalysis induces electron and hole pairs in the conduction band (CB) and valence band (VB) of a semiconductor when irradiated with photons that match or exceed the energy gap ( E g ) of the semiconductor, typically in the UV and visible regions of light. 10 Electron and hole pair (e − /h + ) couples can contribute to pollutant degradation directly or indirectly. Photoinduced electrons are powerful reducing agents that may degrade pollutants via reduction processes.…”

“…Actually, the use of semiconductor materials reduces the costs of heterogeneous photocatalysis and enables the mineralization of various organic compounds without any additive [14]. Several semiconductors have been used in photocatalytic degradation of environmental contaminants, including titanium dioxide (TiO 2 ), zinc oxide (ZnO), tungsten oxide (WO 3 ), tin oxide (SnO 2 ), zirconium oxide (ZrO 2 ), cadmium sulfide (CdS), and others [14,[16][17][18][19][20][21][22][23]. Among many semiconductors, TiO 2 has attracted much attention by different research groups [24][25][26][27][28] because it is inexpensive and chemically stable [29,30].…”
