Anodic Electrocatalysis of Glycerol Oxidation for Hybrid Alkali/Acid Electrolytic Hydrogen Generation
摘要
Abstract
Electrolytic hydrogen production is heavily restricted by high-energy consumption majorly due to the relatively high potential of anodic oxygen evolution reaction(OER).Development of OER-alternative reaction at the anode has been recently proposed as a promising pathway to address the associated issues.In this work,we report a hybrid acid/alkali dual-electrolyte electrolyzer by coupling acidic hydrogen evolution reaction(HER)using commercial Pt/C cathode with alkaline electrocatalytic glycerol oxidation(GOR)which is implemented by developing a nickel foam(NF)supporting Co3O4 nanosheets anode that shows low overpotential and high selectivity toward GOR for formate production.The hybrid acid/alkali electrolyzer only requires an applied voltage of 0.55 V to achieve the electrolytic current density of 10 mA cm-2 for glycerol conversion into formate at the anode and H2 production at the cathode with the Faraday efficiency of about 100％.The present work may open a new avenue to maximize the electron uti-lization efficiency and implement the energy-saving green route for H2 generation.关键词
