Abstract: A method for improving peroxidase-like activity of nanozyme and a product thereof are disclosed, which relate to the field of artificial enzymes in biochemistry. The method adopts a hydrogen peroxide solution with high concentration to treat the VO2(B) powder for obtaining a product with high peroxidase-like activity. Compared with the pure VO2(B) powder, the peroxidase-like activity of the product obtained by the method is increased by 4 to 12 times. The method provided by the present invention adopts raw materials with low cost and mild reaction conditions, is simple in operation and low in cost, which is conducive to batch preparation. The powder product obtained by the method is able to be applied to detect hydrogen peroxide, glucose, etc., and has great application prospects in biosensing, industrial wastewater treatment and sewage treatment.
