Hollow N-doped carbon nanocages anchoring Ni–Ru bimetallic nanoparticles for enhanced peroxidase-like activity
Abstract
formation and uniform anchoring of Ni-Ru alloy NPs on the N-doped carbon framework. The resultant Ni/Ru@HNCs exhibit exceptional peroxidase-mimicking activity, efficiently catalyzing the oxidation of 3,3',5,5'-tetramethylbenzidine (TMB) to yield a vivid blue product (oxTMB). Capitalizing on this robust catalytic performance, a sensitive colorimetric sensing platform is established for the rapid and selective detection of tea polyphenols (TP). This work not only demonstrates a rational design of high-performance bimetallic nanozymes with precisely controlled structure and composition but also provides a versatile, scalable strategy for developing advanced enzyme-mimetic materials for biosensing and food safety applications.
