Abstract
Copper (Cu)-based nanoparticle catalysts have emerged as promising alternatives to noble metal catalysts due to their abundance and cost-effectiveness. However, challenges such as nanoparticle aggregation and oxidation hinder their reusability and overall performance. In this study, we present a highly efficient one-pot synthesis method for Cu-based core-shell catalysts through a combination of impregnation and in situ post-calcination. By incorporating hierarchically porous carbon structures in the core-shell configuration, we effectively mitigate agglomeration and complete oxidation of Cu nanoparticles. The resulting catalysts demonstrate outstanding catalytic performance and long-term stability in 4-nitrophenol reduction and benzyl alcohol oxidation reactions. Overall, our straightforward and rapid synthesis strategy offers a novel approach for fabricating Cu nanoparticle catalysts with exceptional activity and durability, paving the way for sustainable catalytic transformations.
