羟基巢介导的PtZn/TS-X催化剂构建及其高效催化丙烷脱氢
Construction of PtZn/TS-X catalyst mediated by hydroxyl nests and its high-efficiency catalytic performance for propane dehydrogenation
摘要
Abstract
Acid etching enables the enrichment of abundant hydroxyl nests on the surface of titanium silicalite(TS).These hydroxyl nests offer stable anchoring sites for the immobilization of active components,facilitating synergistic interaction with PtZn bimetallic species and enhancing propane dehydrogenation(PDH)catalytic performance.Based on this concept,in the present work,TS supports were etched using hydrochloric acid with varying concentrations,and a series of PtZn/TS bimetallic catalysts were fabricated via the co-impregnation method.The effects of acid concentration on the catalyst structure,surface properties,and PDH catalytic performance were systematically investigated.Comprehensive characterization results reveal that acid etching induces the formation of surface-enriched hydroxyl nest structures on TS supports.These structures act as efficient anchoring centers for PtZn species,leading to enhanced dispersion and increased exposure of metallic Pt0 species,thereby lowering the energy barrier for the PDH reaction.This study thus provides a feasible and rational strategy for the design of high-performance PDH catalysts.关键词
