Facile Synthesis of CuOCoOOH Composite Electrocatalyst for Efficient Glucose Electrooxidation

Abstract

Glucose electrooxidation has gained much attention in biomass conversion and sustainable energy, while the challenge of high selectivity and fast conversion rate is still existing. Herein, facile synthesized copper cobalt oxyhydroxide nanosheets enabled complete conversion of glucose to formic acid with 98.7% selectivity and carbon dioxide was the only minor byproduct in just three hours. When scaling up the reactor two and four times, it still achieved around 90% and 68% conversion, with formic acid yields of 75% and 47%. These results show great potential in further scale-up experiments in production of formic acid via glucose electrooxidation.
