| 摘 要： | 采用贵金属沉积法制备了Pt/TiO2光催化剂,在沉积过程中,TiO2的晶体结构保持完整,金属Pt以Pt0价态高度分散在TiO2表面,制备的Pt/TiO2光催化活性明显高于未掺杂的TiO2,提高了光催化产氢性能。以正丙醇为牺牲剂,考察了正丙醇的初始浓度、溶液pH值对产氢过程的影响。结果表明：利用正丙醇溶液产氢,产氢量随着溶液浓度的增加而增加;醇溶液pH值为5时,光催化产氢性能最好,强酸强碱条件均不利于光催化产氢。 |

| Abstract: | Pt/TiO2 is prepared by the noble metal deposition method,the crystal structure of TiO2 remained intact in deposition process and Pt is highly dispersed as Pt0 on the surface of TiO2,photocatalytic activity of Pt/TiO2 is higher than undoped TiO2 and improved its activity of photocatalytic H2 production.Used n-propanol solution as sacrificial reagent,effect of n-propanol initial concentration and solutionpH are studied.Experimental result shows that hydrogen production increases with concentration increasing of n-propanol solution,the best performance photocatalytic hydrogen production when the pH valueis 5,strong acid and strong base both go against photocatalytic hydrogen production. |
| Keywords: | Pt/TiO2 photocatalytic n-propanol hydrogen production |
