Abstract Cu-based copper nanoclusters have generated a great deal of interest based on for their fluorescent and catalytic properties. However, as heterogeneous catalysts, little attention has been given to the degradation of organic pollutants in Fenton-like reaction systems. Here, flower-like copper nanoclusters/flower carbon heterostructured microspheres were prepared by a onepot mixing template-based method. With Cu-based copper nanoclusters/carbon (CuNCs/C) composite as a Fenton-like catalyst, a CuNCs/C-H2O2 system was used to degrade Amido Black 10B (AB-10B). The effects of different factors on the degradation rate of AB-10B were studied. A 98.6% degradation ratio of AB-10B was reached for the CuNCs/C -H2O2 based Fenton-like reaction within 180 min under optimal experimental conditions. The CuNCs/C concentration was 0.06 g/L, the dosage of H2O2 was 25 mmol/L, the mass ratio of CuNCs and the carbon was 1:2, pH = 6.0, and the reaction temperature was 40.0 °C. The removal rate of AB10B on CuNCs/C decreased by less than 10% even after 6 catalytic cycles, which showed a remarkable reusability characteristic and high catalytic activity. Cu0 and Cu+ were found to co-exist in the catalysts and presented

1 Introduction The wastewater of printing and dyeing contains a wide range of synthetic dyes contaminants that must be treated to avoid environmental hazards (Holkar et al. 2016). Azo dyes, with at least one azo group (–N=N–), are one of the largest groups of synthetic dyes used in industrial applications because they are easy to use and provide clear and strong colors (Konstantinou and Albanis 2004). Amido black 10B (AB-10B) is an acidic synthetic dye containing two azo groups and is one of the commonly used azo dyes used in the dyeing process of different textile products. AB-10B is also used as a protein-containing stain and can damage human health with its high toxicity (Carvalho da Cruz Brambilla et al. 2019). However, AB-10B is resistant to decolorization, shows low bio-degr
