CORREDOR-ROJAS, Laura Milena. Review of Photocatalytic Materials for Hydrogen Production from H₂S². Ing. Univ. [online]. 2011, vol.15, n.1, pp.171-195. ISSN 0123-2126.

Based on the work carried out by Fujishima and Honda (1972), who accomplished the electrochemical photolysis of water on a TiO₂ electrode, numerous researchers have extensively studied water and sulfide hydrogen splitting by using semiconductor photo-electrodes and photocatalysts for producing hydrogen. Current research is focused on the development of a stable material with visible-light response. Both the catalytic activity of the semiconductor and the design of the reactor influence the possibility of applying photocatalytic reactions to industrial processes. Different types of reactors have been tried but, so far, a successful laboratory photocatalysis setup has not been scaled up to an industrially relevant scale. This paper presents a review of heterogeneous photocatalyst materials for hydrogen production based on direct and indirect conversion of hydrogen sulfide. Additionally, this study proposes a number of schemes for integrating photo-assisted reactions with industrial processes for H₂S treatment.

Palavras-chave : Photocatalysis; hydrogen sulfide; hydrogen.
