Published in International Journal of Extreme Manufacturing, Prof. Zhang’s team from Harbin Institute of Technology comprehensively introduced the utilization of single atom catalysts within the field of gas sensing, proposing a new strategy to enhance the performance of gas sensors further.
This review primarily discusses the application of single-atom catalysts in the field of gas sensing. Specifically, it summarizes the structure and principles of semiconductor-based gas sensors and reviews the latest methods for preparing single-atom catalysts.
It also analyzes the mechanisms through which single-atom catalysts enhance gas sensitivity from two perspectives, providing a detailed overview of the performance of single-atom catalysts in gas sensing.
