Non-quantum nanostructures-enabled hot carriers generation for enhancive photoelectrocatalytic oxidation of bio-alcohol in water coupled with hydrogen evolution<\/strong><\/p>\n

Recently, PhD student Mr Pei-dong Wu supervised by Profs. Hu Li and Zhen Fang<\/strong> published research article in Green Chem<\/strong> about photoelectrocatalytic oxidation of bio-alcohol in water coupled with hydrogen evolution.<\/p>\n

Photoelectrochemical system is a promising way for biomass valorization but still in its infancy. Herein, a Mo-BVO-TiCoNO-CoFeOxy<\/sub><\/em> photoanode with a nanowire structure was prepared for efficiently converting bio-based benzyl alcohol (BA) to benzoic acid (97.7% yield) for the first time, while coupling H2<\/sub> production of 136.8 \u00a0\u03bcmol cm-2<\/sup>. The nanowire structure enables a significant increase in the exposed active sites on the photoelectrode surface to enhance the BA oxidation capacity, whereas its large aspect ratio increases the visible light absorption and thermal effect (resulting from size effect) increases H2<\/sub> production at the counter electrode. DFT calculations and further experiments revealed that Co species of the CoFeOxy<\/sub><\/em> layer functioned as stabilizers of photoelectrode property while Fe species acted as catalytic site providers in the BA oxidation.<\/p>\n

The use of photoelectrochemical system for the high value use of biomass-derived alcohols coupled with hydrogen production is a significant contribution to the \u201ctwo-carbon\u201d. The loading of a “two birds with one stone” CoFeOxy<\/sub><\/em> layer on BVO substrate enabled rapid separation of photoexctied carriers while achieving a 97.7% yield of benzyl alcohol (BA) to benzoic acid (BEN). \u4f7f\u7528\u5149\u7535\u5316\u5b66\uff08PEC\uff09\u7684\u65b9\u6cd5\u5c06\u751f\u7269\u8d28\u884d\u751f\u9187\u9ad8\u503c\u5316\u5229\u7528\u8026\u5408\u4ea7\u6c22\uff0c\u5bf9\u4e8e\u201c\u53cc\u78b3\u201d\u76ee\u6807\u7684\u5b9e\u73b0\u5177\u6709\u6781\u5927\u7684\u4fc3\u8fdb\u610f\u4e49\u3002\u6211\u4eec\u5728\u9492\u9178\u94cb\u57fa\u5e95\u4e0a\u8d1f\u8f7d\u5177\u6709\u201c\u4e00\u77f3\u4e8c\u9e1f\u201d\u4f5c\u7528\u7684CoFeOxy<\/sub>\u5916\u5c42\u5b9e\u73b0\u5149\u81f4\u8f7d\u6d41\u5b50\u7684\u5feb\u901f\u5206\u79bb\uff0c\u540c\u65f6\u5b9e\u73b0\u5bf9\u82ef\u7532\u9187\uff08BA\uff09\u5230\u82ef\u7532\u9178\uff08BEN\uff0997.7%\u7684\u4ea7\u7387\u3002<\/p>\n
