Nanozyme is a promising field that offers the substitution for natural enzymes using various *** nanoma-terials with peroxidase-like activity were *** them,transition metal chalcogenides were explored as promis-ing nanozymes due to their excellent enzyme-mimicking ***,ruthenium selenide has not been studied as a peroxidase mimic because of the difficulty for ***,we prepared ruthenium selenide nanomaterial with ordered mesoporous structure(P-RuSe_(2))employing KIT-6 silica as the *** composition and structure of P-RuSe_(2) were fully ***,its peroxidase-like activity was investigated.P-RuSe_(2) possessed excellent peroxidase-mimicking activ-ity,which catalyzed the oxidation of peroxidase substrates,including 3,3′,5,5′-tetramethylbenzidine,o-phenylenediamine,and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)in the presence of H_(2)O_(2).Moreover,P-RuSe_(2) exhibited higher peroxidase-like activity when compared with several representative nanozymes as well as bulk RuSe_(2).To demonstrate its potential applications,the colorimetric detection systems for H_(2)O_(2) and glucose were successfully constructed based on P-RuSe_(2) nanozyme.
