I will review recent progress in CO2 reduction electrocatalysis toward sustainable chemicals. This will include a discussion of systems that enable the needed high rate of electroproduction in order to render capital costs acceptable. It will also include work on the catalysts and their electrolyte that are capable of producing a relatively high selectivity towards a desired product, such as for example ethylene. Overall I will look at further progress needed to achieve high CO2 utilization, and - crucially - to continue to increase energy efficiency on the path towards prospective technoeconomic viability. The approaches used will include computational studies as well as nanomaterials synthesis and in situ spectroscopies.
