Biogenic silver nanoparticle impregnated hollow mesoporous silicalite-1: an efficient catalyst for p-nitrophenol reduction

AgNP impregnated hollow mesoporous silicalite-1 was synthesized using green carambola extract. AgNPs of 10-15 nm size were well dispersed mostly within the shell of hollow silicalite-1 which contained hierarchical porosity. The synthesized product showed enhanced catalytic efficiency for the reduction of p-nitrophenol.
