Stable Cu Catalysts Supported by Two-dimensional SiO₂ with Strong Metal-Support Interaction.

ABSTRACT: Cu-based catalysts exhibit excellent performance in hydrogenation reactions. However, the poor stability of Cu catalysts under high temperatures has restricted their practical applications. The preparation of stable Cu catalysts supported by SiO₂ with strong metal-support interaction (SMSI) has thus aroused great interest due to the high abundance, low toxicity, feasible processability, and low cost of SiO₂ . The challenge in the construction of such SMSI remains to be the inertness of SiO₂ . Herein, a simple and scalable method is developed to prepare 2D silica (2DSiO₂ ) supported Cu catalysts with SMSI by carefully manipulating the topological exfoliation of CaSi₂ with CuCl₂ and thereafter calcination. The prepared Cu-2DSi
