Rationally regulating the photogenerated carrier transfer behavior and band structure of TiO2 through metal doping is an effective strategy for enhancing photocatalytic activity in removal malodorous gas hydrogen sulfide (H2S). In this study, modified with Group IIIA ions (Al3+, Ga3+, In3+) was utilized as efficient desulfurizer under ultraviolet irradiation. Among these samples, 4% In-TiO2 exhibited best H2S efficiency 100% a duration 120 min, nearly 3 times higher than that commercial P25 TiO2. The UV–vis DRS PL spectra demonstrated incorporation Group-IIIA into resulted formation shallow acceptor level above valence energy structure, which induced slight redshift at edge visible light absorption reduced electron–hole recombination rate. situ DRIFTS DFT calculations revealed adsorption activation occurred simultaneously on In-TiO2, facilitated by its strong oxygen vacancy capability. ln3+ promoted photothermal-catalytic oxidation reaction surfaces thereby significantly desulfurization H2S. This study not only offers deeper understanding regulated ions, but also provides promising green

Acid gas, which contains toxic hydrogen sulfide, is produced by several sources, including refineries and processing plants for natural gas. Catalytic decomposition reforming of H2S offer viable ways to produce from a waste resource, with the added benefit reducing pollution. However, conventional thermolysis traditional Claus process, highly endothermic exhibits low conversion at reaction temperatures. While photocatalytic pathway would less energy-intensive pathway, its overall efficiency regarding light/heat absorption utilization needs be further enhanced. Hydrogen sulfide can converted via photothermocatalysis into elemental sulfur hydrogen, two value-added products. This process addresses drawbacks pure photo thermal procedures could approach treating streams. study extensively examines potential interaction between photo- thermocatalytic systems, concentrating on hydrogen. The aim provide valuable insights pathways future optimization. For first time, as per literature survey, photothermocatalytic that extended both reformation toward production proposed, considering current challenges prospects.
