ABSTRACT
7.1 INTRODUCTION
CO2 electroreduction involves multielectron processes which can form a large variety of products ranging from CO, CH4 to higher hydrocarbons in the gas phase, and generate various oxygenates in the liquid phase such as alcohols, aldehydes, and carboxylic acids. Currently, controlling the CO2 reduction pathways is still a challenging work. A thorough and accurate determination of products is of critical importance for the evaluation of electroreduction performance. Many groups have practically adopted the routine analysis of one or two products in either gas or liquid phase for evaluation of electrocatalytic efficiencies. However, to date, only very few studies have been focused on the analysis of reduction products, and more comprehensive and standard analysis methods are not yet reported in the literature. In this chapter, different analysis methods reported so far are summarized.
