Construction of a Cu3+–OH–Pt interface for enhancing glycerol electrooxidation coupled with hydrogen evolution
DOI: 10.1039/D5GC00931F, PaperKaiwei Meng, Ziyi Fan, Huiming Wen, Yujie Hu, Wenjun Zhang, Zupeng Chen
Pt/CuO NRs catalyze efficient glycerol electrooxidation with ~100% conversion and 97.4% FA selectivity during 100-h stable MEA test. EIS, in situ Raman, and DFT reveal Pt0 boosts electron transfer, Cu3+–OOH formation, and weakens O–H bonds.
