摘　　要：研究了以乙二醇为电子给体在Pt/TiO2上光催化分解海水制氢的反应。研究了反应时间、乙二醇起始浓度、溶液pH值、乙二醇中共存物甘油和葡萄糖对光催化放氢的影响。结果表明乙二醇能显著地提高光催化分解海水制氢效率,并且其自身的降解活性也很好。Using glycol as electron donor, the photocatalytic hydrogen generation from seawater over Pt/TiO2 has been investigated. The factors which affect photocatalytic hydrogen generation, such as irradiation time, initial concentrations of the glycol solution, pH value of the suspensions and the coexisting substances were studied. The results show that glycol can not only improve the efficiency of photocatalytic hydrogen generation but also be decomposed effectively.
