Abstract

High entropy alloy (HEA) nanoparticles composed of five or more elements in nearly equimolar concentrations are gaining attention due to their excellent thermal, electrical and catalytic behavior [1]. The application of HEA as a heterogeneous catalyst in energy conversion applications exhibit substantially enhanced catalytic activity compared to noble metal (Au, Ag, Pt, Pd) based catalysts [2]. HEA/Graphene (HEA:G) composites with varied weight percentage ratios of HEA and graphene have shown remarkable catalytic behavior towards water oxidation and non-enzymatic urea detection [3-4]. This response is due to the synergistic effect of HEA in catalyzing the redox reaction and graphene in accelerating the electron transfer process. Hence HEA based composites can replace traditional metal-based catalysts and can bring a great revolution in energy storage and sensing applications. This work illustrates the electro-catalytic behavior of HEA:G towards enzyme-less oxidation of glucose.
