Abstract

In this work, we report the design and synthesis of a series of heterostructured SnO₂-CuO hollow microspherical catalysts (H-SnO₂(x)-CuO, x is the weight ratio of Sn/Cu) for the Rochow reaction. The microspherical catalysts with nanosheets and nanoparticles as building blocks were prepared by a facile one-pot hydrothermal method coupled with calcination. When tested for the Rochow reaction, the prepared H-SnO₂(0.2)-CuO composite exhibited higher dimethyldichlorosilane selectivity (88.2%) and Si conversion (36.7%) than the solid CuO, hollow CuO and other H-SnO₂(x)-CuO microspherical samples, because in the former there is a stronger synergistic interaction between CuO and SnO₂.
