Colorimetric Method Based on CeO2/CoOOH Nanozyme for Rapid Detection of Ascorbic Acid in Fruits

In this study, cerium dioxide-modified cobalt oxyhydroxide (CeO2/CoOOH) nanomaterial was synthesized by a liquid-phase precipitation method. 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 blu...
