Abstract
An electrocatalyst comprising bismuth nanodot-doped zinc materials is used for electrochemical reduction of carbon dioxide to formate. The electrocatalyst consists of bismuth nanodots dispersed on a zeolitic imidazolate framework-8 wherein the bismuth-zinc material is in the form of particles with a longest dimension of 200 to 1000 nm. The bismuth-zinc material is utilized in H cell, flow cell, and MEA cell applications for carbon dioxide reduction.
