Zhongyuan Institute of Technology developed a new dye degradation catalyst

On July 2nd, the news came from Zhongyuan University of Technology, the project of “Three-dimensional skeleton in-situ construction of high-efficiency textile dye wastewater degradation technology research and application” hosted by Mi Liwei, Dean of the School of Materials and Chemical Engineering and Director of Advanced Materials Research Center. It passed the evaluation of the expert results organized by the Research Management Research Association of Henan Province. The expert group agreed that the project technology has reached the domestic leading level.

It is reported that the textile printing and dyeing industry is a major industrial wastewater discharger. It has become a difficult source of industrial wastewater at home and abroad due to its large color of dye wastewater, high content of organic pollutants, complex components and high biological toxicity.

The project evaluated by the results is based on in-situ growth technology, and a series of copper-based chalcogenides are constructed on the surface of the foamed copper of the three-dimensional network structure, which can realize the organic combination of the catalyst and the carrier. The compound uses the ion exchange method to regulate the active center of the multi-Fenton-Fenton catalyst, and increases the number and type of metal active sites on the catalyst surface. A new preparation process of high-efficiency dye degradation catalyst is proposed. The project achieves catalytic degradation of high-concentration and multi-component textile dye wastewater, and solves the problem of difficult catalyst recovery and recycling.
