The electrochemical CO2 reduction reaction (CO2RR) to methanol offers an eco-friendly approach to 

reducing carbon emissions while producing versatile liquid fuels and feedstocks. However, achieving 

high selectivity for methanol, especially at high current densities, remains challenging due to competing 

reactions that favor methane and hydrogen formation. Here, the tailored synthesis of Cu/Cu2P2O7-

based hybrid catalysts is reported for efficient and selective methanol production through the discharge

of lithium-ion batteries. The catalyst exhibits a Faradaic efficiency exceeding 50% in both H-cells and 

gas-diffusion electrode cells, achieving one of the highest reported methanol partial current densities of 

over 100 mA cm−2. Experimental and computational analyses reveal a synergistic effect between Cu

nanoparticles with a predominant (111) surface and Cu2P2O7 nanoparticles, which enhances selective 

methanol production via the HCOOH intermediate pathway. These findings provide insights into designing 

cost-effective electrocatalysts for selective methanol production.
