| 摘 要： | 研究了葡萄糖为电子给体在Pt/TiO2上光催化生成氢的反应.葡萄糖明显提高了制氢反应效率,反应5 h内,反应生成氢的量与反应时间成线性关系;葡萄糖初始浓度对生成氢反应速率的影响符合Langmu ir关系式;考察了无机离子对光催化反应的影响;用循环伏安法对光催化反应进行监测,发现降解过程中生成了葡萄糖酸.讨论了可能的反应机理.

| Abstract: | Using glucose as electron donor,the photocatalytic hydrog en evolution over Pt/TiO_2 has been investigated.Glucose obviously enhances ph otocatalytic hydrogen generation activity.The amount of produced H_2 increases almost proportionally to the irradiation time within 5 h irradiation.The effec t of the concentration of glucose on the reaction rate is consistent with the La ngmuir-Hinshelwood kinetic model.The effect of inorganic anions on photocatalyt ic hydrogen evolution has been investigated.The photocatalytic reaction process was monitored by cyclic voltammetry.The result shows that gluconic acid is pro duced in photocatalytic degradation process of glucose.A possible reaction mech anism was discussed. |
