REDUCTION OF CARBON DIOXIDE TO FORMIC ACID IN A SOLID POLYMER ELECTROLYTE (SPE) REACTOR

摘要

The research reports an investigation of an inherently clean and selective process for the electrocatalytic reduction of carbon dioxide to formic acid. The research evaluated electrocatalytic metalised (In, Pd, Pb, Pt, Pt/Ru, Cu) graphites for the reduction of carbon dioxide and unsupported metal deposited SPE electrode structures, using a range of membrane materials as alternatives to Nafion~R, including anion exchange membranes. Good yields of formic acid were produced with all catalysts, except Pt and Pt/Ru.
