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.
