摘要：

Hydrogen gas obtained from illuminated p-CuInSe2 (CIS) on 0.5 M sulfuric acid solution was collected in a glass balloon using argon as carrier gas, and quantified with a mass spectrometer. p-CuInSe, thin films were electrodeposited on SnO2-coated glass plates, according to references already reported. Electrochemical deposition of Se and chemical modifications on the semiconducting surfaces with adsorbed ruthenium were also tested for the hydrogen evolution reaction. The E-g and E-tb of the modified p-CuInSe2 were determined. Atomic absorption spectrometry was used to quantify the chemical compositions of the semiconductors before and after the illumination. The modified semiconductors had a composition of CIS/Se-24 and CIS/Se-6/(RuO4)(0.12), under illumination at 0.8V in 0.5 M H2SO4 for 4 min, the volumes of evolved hydrogen were 1 cm(3) and 2.4 cm(3), respectively.
