研究目的
To develop efficient heterogeneous copper catalysts that can perform the green synthesis of conjugated 1,3-diynes under ligand- and base-free conditions.
研究成果
The prereduced CuFe2O4 is an effective heterogeneous catalyst for both thermocatalytic and photocatalytic oxidative homocoupling of terminal alkynes, with the photocatalytic efficiency at ambient temperature comparable to thermocatalysis at 120 oC. The LSPR effect of CuNPs contributes to the visible light-induced photocatalytic OHA.
研究不足
The gradual deactivation of the catalyst due to copper leaching in thermocatalytic OHA and oxidation of CuNPs in photocatalytic OHA.
