碳模板改性水滑石和水滑石负载钯催化剂的合成及催化性能研究的中期报告 摘要： 本研究合成了碳模板改性水滑石和水滑石负载钯催化剂，并对其催化性能进行了研究。通过SEM和TEM等表征手段，发现碳模板改性水滑石和水滑石负载钯催化剂具有较高的比表面积和孔体积，且呈现出均匀的孔径分布。实验结果表明，碳模板改性水滑石负载的钯催化剂表现出较高的催化活性和稳定性，在Pd的负载量为5%时最佳，随着Pd的负载量增加，催化活性略有下降。水滑石负载的钯催化剂在Pd的负载量为5%时表现出最佳的催化活性和稳定性，但其催化活性略低于碳模板改性水滑石负载的钯催化剂。 关键词： 碳模板、水滑石、钯催化剂、负载、催化性能 Abstract: In this study, carbon template-modified talc and talc-supported Pd catalysts were synthesized and their catalytic properties were investigated. Through characterization methods such as SEM and TEM, it was found that the carbon template-modified talc and talc-supported Pd catalysts had high specific surface area and pore volume, and showed a uniform pore size distribution. The experimental results showed that the Pd catalyst supported on carbon template-modified talc exhibited higher catalytic activity and stability, and the optimal Pd loading was 5%. With increasing Pd loading, the catalytic activity slightly decreased. The talc-supported Pd catalyst exhibited the best catalytic activity and stability when the Pd loading was 5%, but its catalytic activity was slightly lower than that of the carbon template-modified talc-supported Pd catalyst.
