摘要：

Cobalt nanoparticles containing SBA-15 intercalated Mg-Al hydrotalcite composites (MSB) supports were prepared with cobalt content in the range of 1-15 wt%. The uniform cobalt nano particles with particle size of 3-10 nm were evident from HR-TEM analysis. The powder XRD studies reveal the layered HT and mesoporous SBA-15 structure retains even after 15 wt% of cobalt nano particles loading. The nanoparticles loaded materials show good catalytic activity for hydroformylation of olefin using syn-gas. The maximum conversion of about 65% with the exclusive formation of hydroformylated products was observed.
