CdS-based photocatalyst for hydrogen evolution from the cellulose aqueous suspension.

Cellulose has been shown to be a perspective substrate for the photocatalytic hydrogen evolution over CdS- based photocatalyst under visible light irradiation (450 nm). Multiphase photocatalyst was synthesized throw simple two- stage method. Samples obtained were characterized by UV-Vis spectroscopy and XRD techniques. The influence of such reaction parameters as photocatalyst loading, substrate concentration and pH was investigated. The highest hydrogen evolution rate equaled to 0.8 mmol·h^-1·g_cat⁻¹ with the calculated apparent quantum yield of 1.1 %. [ABSTRACT FROM AUTHOR]
