Comparative activity of CdS nanofibers superficially modified by Au, Cu, and Ni nanoparticles as co-catalysts for photocatalytic hydrogen production under visible light

摘要

BACKGROUNDThe use of CdS as a catalyst under visible light for hydrogen production has attracted much attention owing to its ability to perform the photocatalytic hydrogen production under visible light; the use of noble metals as co-catalysts has been reported as an effective method to increase their efficiency. This work compares the activity of CdS catalysts using different metals as co-catalysts supported on its surface, such as gold, and non-noble metals such as Cu and Ni, enhancing the photocatalytic response.
