Method & Evidence

AimCan entropy-stabilized high-entropy oxides (HEOs) with embedded metal alloys serve as effective bifunctional catalysts for the selective aqueous-phase hydrogenolysis of cellulose to ethylene glycol?
MethodExperimental research and chemical engineering
ProcedureA polyvinylpyrrolidone (PVP)-assisted sol-gel strategy was employed to synthesize a Pd/WMoAlNiSiOx catalyst. This involved embedding Pd nanoparticles and PdNi alloy domains within an entropy-stabilized high-entropy oxide (HEO) matrix. The catalyst's performance was evaluated for the selective conversion of cellulose to ethylene glycol under mild hydrothermal conditions (245°C, 4.5 MPa H2). Characterization techniques and kinetic studies were used to understand the catalytic mechanisms and performance enhancements.
