Colorimetric Method Based on CeO2/CoOOH Nanozyme for Rapid Detection of Ascorbic Acid in Fruits by YUE Xiaoyue, WU Chaoyun, YAN Shuliang, FU Long, ZHAO Dianbo

“…CeO2/CoOOH showed good oxidase-like activity toward 3,3’,5,5’-tetramethylbenzidine (TMB), and could directly oxidize TMB to ox-TMB, which presented a clear blue color. Reversely, ascorbic acid (AA) could reduce ox-TMB to TMB, leading to a decrease in the absorbance of ox-TMB at 652 nm and a fading of the blue color. …”
