Enhanced strong metal–support interactions between Pt and WO3–x nanowires for the selective hydrogenation of p-chloronitrobenzene

Abstract

WO_3–x nanowires with oxygen vacancies synthesized by a hydrothermal method were employed as supports to deposit Pt nanoparticles (NPs) via a deposition–reduction method with NaBH₄. The Pt/WO_3–x nanocomposites exhibit an excellent catalytic hydrogenation performance in the selective hydrogenation of p-chloronitrobenzene due to the interaction between Pt NPs and WO_3–x nanowires.
