光催化制氢研究了甲酸溶液与二氧化钛（TiO 2）的援助，同时铑沉积。最佳条件为：Rh负载量0.1wt%、甲酸浓度1.0%、溶液pH 2.2、温度50 °C。在最佳条件下，黑光灯照射1 h、3 h和5 h后，光催化反应的产氢量分别为5.0 mmol g-1、12.2 mmol g-1和16.0 mmol g-1。采用XRD、SEM、光致发光光谱、漫反射光谱和BET比表面积等手段对Rh/TiO 2光催化剂进行了表征。并提出了Rh/TiO 2光催化甲酸制氢的反应机理。
Photocatalytic hydrogen production was studied with a formic acid solution with titanium dioxide (TiO2) with the aid of simultaneous Rh deposition. The optimum conditions were as follows: Rh loading, 0.1 wt%; formic acid concentration, 1.0%; solution, pH 2.2; temperature, 50 °C. Under the optimum conditions, the photocatalytic hydrogen production with TiO2 by the simultaneous deposition of Rh was 5.0 mmol g−1, 12.2 mmol g−1 and 16.0 mmol g−1 after 1 h, 3 h and 5 h of irradiation time for black light, respectively. Rh/TiO2 photocatalysts were characterized by XRD, SEM, photoluminescence spectra, diffuse reflectance spectra and the BET surface area. The reaction mechanism of photocatalytic hydrogen production from formic acid by Rh/TiO2 was also proposed.
