AI Technical Summary

Technical Problem

In existing technologies, single-atom catalysts tend to agglomerate at high temperatures, leading to a decrease in catalytic performance. Furthermore, nano-cluster catalysts have low atomic utilization, making it difficult to simultaneously improve catalytic activity and stability.

Method used

By loading Pt onto the ZrW(OH)γ precursor and then subjecting it to calcination and high-temperature reduction, a Pt single-atom-W nanocluster island catalyst with a three-level hierarchical structure of support-nano-island-single atom is formed, ensuring that Pt single atoms are stably anchored on the tungsten nanocluster islands, thus forming a Pt1/Wn/ZrO2-x catalyst.

Benefits of technology

The stability and catalytic activity of Pt single atoms under high temperature conditions were improved. The vinyl chloride oxidation reaction showed good catalytic activity and thermal stability, making it suitable for industrial applications.
