Direct splitting of H2S into H2 and S on CdS-based photocatalyst under visibl…

Abstract. The conversion of H2S into H2 and S (H2S → H2 + S) is beneficial from both environmental and energy standpoints. Here we report that H2S can be splitted stoichiometrically into hydrogen and sulfur on CdSbased photocatalysts under visible light irradiation using ethanolamine as a H2S solvent and reaction media at room temperature. Raman spectra showed that the produced sulfur exi…
