Self-catalytic synthesis of CuO@SiO₂ nanocomposites under neutral condition and its catalytic performance

Herein, we reported a novel strategy to synthesize CuO@SiO₂ nanocomposites under neutral conditions with the self-catalysis effect of APTES and CuBA2 as proper precursor. No additional acid or alkali was required as catalyst during the entire process. On the other hand, the catalytic properties of CuO@SiO₂ composites were evaluated by catalyzing the reduction of 4-nitrophenol using NaBH4 as the reducing agent. The results revealed that the products exhibit excellent catalytic property and cycling performance.
