摘要：

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 H2O2. The optimised AuPdPt/TiO2/PaDa-I system achieves significant improvements over analogous AuPd or Pd-only formulations or the use of commercially available H2O2, with this attributed to the increased rate of H2O2 production by the chemo-catalyst, which results from the electronic modification of Pd species via Pt incorporation, upon the formation of trimetallic nanoalloys.
