説明:

The simultaneous realization of biomass conversion and clean energy hydrogen (H2) production remains a desirable but challenging objective. Herein, we present a strategy that simultaneously enables anodic electrocatalytic xylose oxidation (EXO) coupling with the cathodic hydrogen evolution reaction (HER). In the EXO process, the hierarchical microcolumn NiMoO4 array exhibits excellent performance, achieving 200 and 231 mV reduction of overpotential compared to the oxygen evolution reaction at 10 and 50 mA cm−2, respectively, and an overpotential of 130 mV lower than that of Ni foam at 50 mA cm−2. The mechanism studies reveal that the OH* are effective active species to facilitate the EXO process. For HER, the P-doped NiMoO4 (P-NiMoO4) electrode exhibits remarkable HER performance, achieving 64 and 197 mV overpotential at 10 and 50 mA∙cm−2, respectively.
