| Abstract: | Solar photocatalytic water splitting is one of the best ways for solar hydrogen production. In this paper, CdS is chosen as sensitizer to construct a CdS/titanate nanotube composite semiconductor. Both the concentrations and pH conditions of photocatalytic hydrogen production in different organic agents were investigated. The hydrogen production mechanism was analyzed. It was found that formic acid showed highest activity among various organic agents. Various concentrations with 10%, 20%, 30%, 40% and 50% were investigated and the 20% of formic acid showed best activity. |
