A template-free assembly of Cu,N-codoped hollow carbon nanospheres as low-cost and highly efficient peroxidase nanozymes

Abstract

Developing carbon-based materials with high catalytic performance and sensitivity has significance in the low-cost and highly efficient nanozymes. Herein, Cu,N-codoped hollow carbon nanospheres (CuNHCN) with highly active Cu-Nx sites were...

“…With the rapid development of nanomaterials, a variety of inorganic nanomaterials have attracted considerable attention in the field of catalysis. Since inorganic magnetic oxide (Fe 3 O 4 ) was reported to exhibit peroxidase-like activity in 2007, a large number of inorganic nanomaterials, including metal nanoparticles [ 24 , 25 , 26 ], carbon-based materials [ 27 , 28 ] and metal oxides [ 22 , 29 ], have been explored as enzyme mimics to design and build colorimetric platforms for the on-site detection of analytes. Zhao et al prepared CeO 2 -TiO 2 nanotubes with superior peroxidase-like activity for colorimetric detection of H 2 O 2 and glucose [ 30 ].…”
