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 Cunanoparticles 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.
