A hierarchical honeycomb-structured Pd/MgO/Mg catalyst via microplasma electrolytic oxidation and cathodic etching for efficient green oxidation of hydrosilanes

Abstract

This work presents an “integrated preparation–structural reshaping” strategy, combining microplasma electrochemical oxidation (MPEO) with cathodic etching (CE) to fabricate a Pd/MgO/Mg catalyst with a hierarchical porous-honeycomb structure. This catalyst achieves high catalytic activity for the conversion of dimethylphenylsilane and triethylsilane, with TOFs of 15 561 h⁻¹ and 22 284 h⁻¹, respectively.
