The Preparation of the Mn-Cr/SBA-15 Catalyst and its Ability to Selectively Oxidize Substituted Benzyl Alcohols

In this study, a Mn-Cr catalysts supported on self-synthesized SBA-15 for the oxidation of substituted benzyl alcohols using oxygen as the oxidant had been investigated. The mesoporous nature of SBA-15, characterized by its high specific surface area and regular pore structure, makes it an ideal carrier for catalysts with catalytic properties. Through careful optimization, an efficient Mn-Cr/SBA-15 catalyst had been developed, achieving a benzyl alcohol conversion rate of nearly 90% with a selectivity exceeding 98% towards benzaldehyde and its derivatives. Furthermore, the supported Mn-Cr catalysts exhibited remarkable stability, allowing for their reuse for at least five cycles without significant loss of activity or selectivity. These findings highlight the potential of Mn-Cr/SBA-15 catalysts as sustainable and effective options for the oxidation of substituted benzyl alcohols. The study contributes to the development of greener and more efficient oxidation processes in organic synthesis.
