Nano-catalysis provides many opportunities for chemical transformations, ranging from chemical manufacturing to energy conversion and storage. By far, mainly due to the recovery aspect, heterogeneous catalysis has received significant research attention, with its application covering approximately 80 percent of all catalytic processes.

In order to develop efficient nano-catalysts, it is of paramount importance to gain insights into fundamental properties, such as the coordination structures of the active centers, element-doping-induced electronic effects, and substrate–adsorbate interactions. However, owing to the limitation of the currently available characterization technologies and the diversity of active sites in heterogeneous nano-catalysts, the barrier hampering nano-catalysis has long existed because of the lack of an atomic level understanding of the mechanisms governing the catalytic processes. The nano-catalysis is faced with a major challenge to meet the needs of a sustainable society.

Over the last decade, modern catalysis has entered the golden era owing to the development of single-atom catalysts. With the characteristics of 100 percent dispersion and uniform active centers, the single-atom catalysts offer advanced opportunities for exploring the catalytic performances of metals. More importantly, the studies of the interatomic interactions between the single metal atom and the surrounding environment would shed light on the catalytic process over the multi-atom sites in nano-catalysts.

Recently, a comprehensive account paper on the design of modern heterogeneous catalysts was published in Chinese Journal of Catalysis by a team led by Professor Chen Chen from Tsinghua University, China. This account summarized their extensive investigation of the factors impacting nano-catalysis, along with the synthetic strategies developed to prepare innovative catalysts ranging from single-atom catalysts to nano-catalysts. The application of the catalysts covers electrocatalysis, photocatalysis, and thermocatalysis. The lead author, Chen said: “Our team has long been dedicated to investigating nano-catalysis and exploiting novel catalysts for chemical synthesis and energy conversion. We hope our studies will offer some useful guidelines for the researchers to achieve visible breakthroughs in catalysis science.”
