Abstract

An electrochemical electrode comprising a tin-based catalyst, method of making, and method of use are provided. Catalyst particles are prepared which comprise tin deposits of about 0.1 nm to about 10 nm deposited onto carbon support. Preparing an ink comprising the catalyst particles and a binder enable an electrode to be prepared comprising the catalyst particles bound to an electrode substrate. The electrode may then be used in an apparatus and process to reduce carbon dioxide to products such as formate and formic acid at Faradaic Efficiencies up to 95 percent.
