在这里，我们报告了一个可持续的过程中，光诱导的氢生产从水溶液的含氧烃。N和B掺杂显著提高了TiO2的产氢活性。向水中添加含氧烃既作为氢源又作为电子供体，与纯水的光催化裂解相比，这大大提高了氢的产生。其他生物质衍生的化合物，如葡萄糖和蔗糖也显示出通过这种光催化转化具有制氢的潜力。
Here we report a sustainable process for photo-induced hydrogen production from aqueous solutions of oxygenated hydrocarbons. Doping N and B into TiO2noticeably improves its activity for hydrogen production. The addition of oxygenated hydrocarbons into water serves both as a hydrogen source and as an electron donor, which substantially enhances hydrogen production as compared with that for the photo-catalytic splitting of pure water. Other biomass-derived compounds such as glucose and sucrose are also shown to have potential for hydrogen production by this photo-catalytic conversion.
