A novel metal organic framework (MOF)-derived porous copper/zinc bimetallic oxide catalyst was developed for the photoreduction of CO2 to methanol at a very fast rate of 3.71 mmol gcat−1 h−1. This kind of photocatalyst with high activity, selectivity and a simple preparation catalyst provides promising photocatalyst candidates for reducing CO2 to methanol.

Abstract Here, we report a Cu-based metal-organic framework (Cu-DBC), constructed by the large π-conjugated ligand dibenzo-[g,p]chrysene-2,3,6,7,10,11,14,15-octaol and the square-pyramidal CuO5 nodes, as the photo-coupled electrocatalysts for CO2 reduction to CH4. Under visible light, it exhibits high performance for photocatalytic reduction of CO2 to CH4 with selectivity of 100% and rate of 1.04 μmol g-1 h-1, without additional photosensitizer. Importantly, at -1.4 V vs. RHE, it exhibits high performance for photo-coupled electroreduction of CO2 to CH4 with a Faradaic efficiency (CH4) of 93% and current density of 10.4 A g-1. Theoretical calculations, in-situ infrared spectroscopy investigation and Mott–Schottky measurements showed that the large conjugated ligand in Cu-DBC has the suitable lowest unoccupied molecular orbital (LUMO) to match well with the reduction potential of CO2/CH4 and serves as a photoswitch to regulate electron transfer pathway to the metal center, resulting highly selective photocatalytic reduction or photo-coupled electroreduction of CO2 to CH4.

Pd, Cu, and Zn trimetallic metal-organic framework electrocatalysts (PCZs) based on benzene-1,3,5-tricarboxylic were synthesized using a simple solvothermal synthesis. The as-synthesized PCZ catalysts exhibited as much as 95% faradaic efficiency towards CO, with a high current density, low onset potential, and excellent long-term stability during the electrocatalytic reduction of CO2.
