Abstract High-entropy alloys (HEAs) have been intensively pursued as potentially advanced materials because of their exceptional properties. However, the facile fabrication nanometer-sized HEAs over conventional catalyst supports remains challenging, and design rational synthetic protocols would permit development innovative catalysts with a wide range potential compositions. Herein, we demonstrate that titanium dioxide (TiO 2 ) is promising platform for low-temperature synthesis supported CoNiCuRuPd HEA nanoparticles (NPs) at 400 °C. This process driven by pronounced hydrogen spillover effect on TiO in conjunction coupled proton/electron transfer. The NPs produced this work were found to be both active extremely durable during CO hydrogenation reaction. Characterization means various situ techniques theoretical calculations elucidated cocktail sluggish diffusion originating from synergistic obtained combination elements.
