ABSTRACT

10.1 INTRODUCTION

The electrocatalytic reduction of CO2 has a long history dating from the nineteenth century. However, this topic becomes more attractive from both academia and industry, because the excessive burning of fossil fuels leads to the extra emission of CO2, which has exceeded nature's CO2 recycle capability. To deal with the extra CO2 recycle, the storage of renewable energy through the electrochemical reduction of CO2 is an attractive strategy to transform the current linear utilization of carbon fuels: the process could be operated under normal condition; the electricity source used to reduce the CO2 could be renewable green energy; the reaction system can be built up to a continuous one and scaled up to realize the industrial application.
