Synergy of a CuO/C3N4 interface and CuO nanoparticles in the ethynylation of formaldehyde for 1,4-butynediol synthesis

Abstract

Catalysts made of CuO/Bi₂O₃ nanoparticles supported on g-C₃N₄ were synthesized using a MOF-derived strategy. The activation of CuO to CuCCCu species and stabilization of the catalyst were facilitated by the synergistic effect of the CuO/C₃N₄ interface and CuO nanoparticles, resulting in enhanced catalytic efficacy in the ethynylation of formaldehyde.
