NH <sub>4</sub> Cl‐Assisted Electrosynthesis of P‐Doped Co(OH) <sub>2</sub> Nanosheet on Cu <sub>2</sub> S Hollow Nanotube Arrays for Glycerol Electrooxidation
The glycerol oxidation reaction (GOR) for producing high-value-added organic compounds is of great research interest due to its potential in alleviating the energy crisis. Herein, a facile NH<sub>4</sub>Cl-assisted electrodeposition strategy is reported to fabricate 3D nano-forest array-like hollow nanostructures. The hierarchical heterojunction by combining phosphorus doping Co(OH)<sub>2</sub> nanosheets with Cu<sub>2</sub>S nanotube arrays (P-Co(OH)<sub>2</sub>@Cu<sub>2</sub>S NTs/CF) is developed to realize the optimization on GOR. The optimized P-Co(OH)<sub>2</sub>@Cu<sub>2</sub>S NTs/CF catalyst exhibits an exceptional activity with a formate Faradaic efficiency (FE) of 97.40% at a potential of 1.30 V (vs RHE). The experimental results indicate that this unique hollow nano-forest structure, grown on a conductive support, can expose more active sites and facilitate electron transfer, thereby demonstrating excellent GOR performance. This work provides new opportunities for the design of electrocatalysts of high-activity and low-cost hollow heterostructure electrocatalysts for glycerol electrooxidation.
