Unique dual responsive activity of a platinum nanozyme stabilized by a green solvent: deep eutectic solvents

Abstract

Cubical Pt nanozymes with a size distribution of 6–8 nm synthesized in and stabilized by eco-friendly choline chloride/glycerol deep eutectic solvent displayed outstanding catalytic performance in the oxidation of uric acid with an activation energy of 37.473 kJ mol⁻¹ and decomposition of en route generated H₂O₂. Significantly, the exploited one pot nanozyme cascade reaction has proven the novel uricase and peroxidase dual responsive enzyme mimetic activity of the ensuing Pt nanocubes unravelling future prime applications.
