Photocatalytic mineralization of hydrogen sulfide as a dual-phase technique for hydrogen production and environmental remediation
TLDR
In this article, the performance of photocatalysts is evaluated in terms of quantum yield, space-time yield, and other operational variables, including mode of operation, irradiation time, and relative humidity.Abstract:
Hydrogen sulfide (H2S) is regarded as a broad-spectrum poison associated with severe health consequences. Among the available treatment options, photocatalytic technology may be effectively applied to the production of hydrogen gas through the splitting of H2S molecules and the addition of 79.9 kJ mol−1 of energy. As a result, advanced photo-reactive media may provide a win-win strategy to treat the parent pollutant (H2S) while producing hydrogen gas. This review encompasses both TiO2 and non-TiO2 catalysts capable of operating under ultraviolet, visible, and solar light irradiation. The performances of photocatalysts are assessed in terms of quantum yield, space-time yield, and other operational variables, including mode of operation, irradiation time, and relative humidity. The concept of space velocity is used to compare photocatalysts in reference to benchmark parameters for the treatment of H2S. This review addresses current limitations and future prospects of the application of photocatalytic technology to efficiently mitigate H2S pollution.read more

Experimental and numerical analysis of the oxidative decomposition of H2S
TL;DR: In this paper, the thermal, oxidative decomposition of H2S in an homogeneous phase has been studied by developing a comprehensive chemical kinetic model for the oxidation of H 2S in a low oxygen atmosphere, by varying the O2/H2S ratio (0.2-0.35), residence time (150-300 milliseconds), and process temperatures (900-1100°C).

Photolysis of low concentration H2S under UV/VUV irradiation emitted from high frequency discharge electrodeless lamps.
TL;DR: The overall ηH2S by photolysis is higher than the combination of ηS by directphotolysis and ozonation, suggesting that hydroxyl radical-mediated indirect photolyism played an important role during photolytic processes.
