doi:10.7517/j.issn.1674-0475.2015.02.117

Abstract

Abstract:

In this paper, a new material containing nickel sulfide, CN-NiS, was obtained by mixing sulfur-polyaniline nanotubes with nickel salt and calcination. TEM, XRD and XPS were used to investigate the composition, strucuture and morphology of CN-NiS. Using fluorescin and triethylamine as the photosensitiser and electron donor, a hydrogen evolution efficiency of 18.6 mmol·g^-1·h^-1 based on CN-NiS could be obtained under optimal conditions. With comparison to polyaniline, sulfur-polyaniline or nickel salt, CN-NiS is a better hydrogen evolution catalyst, indicating the importance of NiS for catalytic hydrogen evolution.

Key words: nickel sulfide, photocatalytic hydrogen evolution, fluorescin, triethylamine
