Nanoconfinement Engineering over Hollow Multi-Shell Structured Copper towards Efficient Electrocatalytical C-C coupling

Chunxiao Liu et al.

Summary: The research found that Cu HoMSs structure has a high selectivity for C2+ products in CO2 electroreduction, and the C2+ Faradaic efficiency increases with the increase in shell numbers. Mechanistic studies show that superposition of Cu shells in HoMSs structure can increase the coverage of CO adsorbate, promoting carbon dimerization.
