AgNP loaded mesoporous γ-Al2O3 samples were synthesized with
two loading percentages (5 and 10 wt% of Ag). Here, AgNO3 was
reduced by trisodium citrate using a molar ratio of AgNO3:trisodium
citrate 1:1. In a typical synthesis of mesoporous γ-Al2O3 with 5 wt.%
AgNP, 10 mL of aqueous solution containing 0.118 g AgNO3 was added
to 1.425 g synthesized mesoporous γ-Al2O3 in a round bottom flask
and allowed to soak for 24 h in a dark chamber with constant stirring
