Abstract
Abstract The introduction of dopant concentrations of Pt into supported AuPd nanoparticles, when used in conjunction with an evolved unspecific peroxygenase (UPO) from Agrocybe aegerita (PaDa‐I) is demonstrated to offer high efficacy towards the one‐pot selective oxidation of cyclohexane to KA oil (cyclohexanol and cyclohexanone), via the in‐situ synthesis of H 2 O 2 . The optimised AuPdPt/TiO 2 /PaDa‐I system achieves significant improvements over analogous AuPd or Pd‐only formulations or the use of commercially available H 2 O 2 , with this attributed to the increased rate of H 2 O 2 production by the chemo‐catalyst, which results from the electronic modification of Pd species via Pt incorporation, upon the formation of trimetallic nanoalloys.
