Abstract

The selective oxidation of olefins is a key academic and industrial research challenge. 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
