Herein, silver was supported on mesoporous silica through a facile synthesis procedure, and characterized using various technics such as FT-IR, XRD, SEM, BET, and EDX. This efficient separable agent alongside aqueous H2O2 was applied to the oxidation of various olefines (1-octen, 1-hexene, cyclohexene, cyclooctene, styrene, and 1, 2-diphenylmethane) to 1, 2-diol under mild reaction conditions (65 ℃) with high conversion and excellent selectivity. The promoter exhibited excellent reusability and stability in the reaction medium.   Highlights Synthesis of new catalyst: Mesoporous silica based silver/H2O2 Selective oxidation of alkenes Recovery of catalyst Efficient catalyst for selective oxidation of olefins to 1,2-diols
