Carbon-based metal-free nanomaterials for the electrosynthesis of small-molecule chemicals:A review
Electrocatalysis is a key component of many clean energy technologies that has the potential to store renewable electri-city in chemical form.Currently,noble metal-based catalysts are most widely used for improving the conversion efficiency of react-ants during the electrocatalytic process.However,drawbacks such as high cost and poor stability seriously hinder their large-scale use in this process and in sustainable energy devices.Carbon-based metal-free catalysts(CMFCs)have received growing attention due to their enormous potential for improving the catalytic performance.This review gives a concise comprehensive overview of re-cent developments in CMFCs for electrosynthesis.First,the fundamental catalytic mechanisms and design strategies of CMFCs are presented and discussed.Then,a brief overview of various electrosynthesis processes,including the synthesis of hydrogen peroxide,ammonia,chlorine,as well as various carbon-and nitrogen-based compounds is given.Finally,current challenges and prospects for CMFCs are highlighted.
