The development of a highly efficient catalyst for CO2 activation and selective conversion to methanol is critical to address the issues associated with the high thermal stability of CO2 and controllable synthesis of methanol.Cu-based catalysts have been widely studied because of the low cost and excellent perfor-mance in mild conditions.However,the improvement of catalytic activity and selectivity remains chal-lenging.Herein,we prepared hollow Cu@ZrO2 catalysts through pyrolysis of Cu-loaded Zr-MOF for CO2 hydrogenation to methanol.Low-temperature pyrolysis generated highly dispersed Cu nanoparticles with balanced Cu0/Cu+sites,larger amounts of surface basic sites and abundant Cu-ZrO2 interface in the hollow structure,contributing to enhanced catalytic capacity for adsorption/activation of CO2 and selective hydrogenation to methanol.In situ Fourier Transform Infrared Spectroscopy revealed the metha-nol formation followed the formate-intermediated pathway.This work would provide a guideline for the design of high-performance catalysts and the understanding of the mechanism and active sites for CO2 hydrogenation to methanol.
