摘要

Faced with economic and environmental challenges, there is a growing demand for durable and efficient catalysts based on non-precious transition metals, which offer both high activity and excellent recyclability. This study focuses on the synthesis of zinc oxide (ZnO) nanoparticles via a hydrothermal method and their characterization using X-ray diffraction and scanning electron microscopy. Furthermore, the study investigates the optimization of reaction conditions and the application of these ligand-free nanocatalysts in the hydrosilylation of alkenes with various hydrosilanes. The silylated products were characterized by 1H, 13C, and 29Si NMR spectroscopy, confirming the successful and efficient conversion of alkenes. The results demonstrate that the catalysts exhibit stable performance even after multiple recycling cycles.
