Coral-shaped tin oxide incorporated graphitic carbon nitride nanosheets as peroxidase mimic for sensitive colorimetric and fluorescence quenching based detection of hydrogen peroxide

The enhanced peroxidase-like catalytic activity of coral-shaped graphitic carbon nitride (GCN) incorporated with tin oxide (SnO2) is here reported and applied for the sensitive and selective colorimetric detection of hydrogen peroxide (H2O2). The SnO2/GCN catalyzed the oxidation of 3, 3′, 5, 5′-tetramethylbenzidine, and H2O2 which resulted in the appearance/change of color in the visible range. The results of peroxidase-like activity showed that...
