摘要：

The photoproduction of hydrogen from alkaline solutions of sulphide/sulphite is one of the photocatalytic processes which has been considered recently for a possible scaling-up. This process could be combined with, or bc an alternative to, the current processes that profit from the sulphur coming from the desulphuration units of oil refineries. Keeping the scaling-up in mind, some basic research and system analysis have been done. Different types of CdS-based semiconductor photocatalysts have been prepared, characterized and tested. A solar simulator device, with a cylinder-parabolic mirror and a tubular photoreactor, has been designed. Studies on the radiation field, fluid dynamics, catalyst stability and kinetic variables have been carried out. The maximum quantum yield obtained was 18%.
