Improved stability and selectivity of CuFe 2 O 4 -based catalysts for photoelectrochemical CO 2 -to-acetate conversion

The newly developed CuFe 2 O 4 -based catalyst demonstrated stable photoelectrochemical (PEC) CO 2 reduction to produce acetate with high selectivity exceeding 90%, thereby solving the stability issue involved in the conventional CuFeO 2 –based catalyst.
