Gold Supported on Aminosilane-Functionalized SBA-15 for Chemoselective Hydrogenation of Crotonaldehyde
Wuli huaxue xuebao
Three kinds of aminosilane (APTS: 3-aminopropyltrimethoxysilane, TPED: N- [3-(trimethoxysilyl)propylethylene]diamine, TPDT: trimethoxysilyl propyl diethylenetriamine) functionalized mesoporous SBA-15 molecular sieves (denoted APTS-SBA-15, TPED-SBA-15 and TPDT-SBA-15) were synthesized by post-grafting. Using the static interaction between the amino group and chloroauric acid followed by chemical reduction, the gold nanoparticles were immobilized into the channels of SBA-15.
