  • About author:Peikun Li (College of Chemical Engineering, Zhejiang University of Technology (ZJUT)) is currently pursuing his Master’s degree under the supervision of Professor Jinghui Lyu. His research is broadly centered on industrial catalysis, with an emphasis on the rational design and synthesis of advanced catalytic materials, catalytic reaction engineering, and the development of transition metal-based catalytic systems. He has a particular interest in zeolite, single-atom catalysts, and electrocatalytic processes, where he seeks to unravel structure-activity relationships and establish strategies for improving catalytic efficiency, selectivity, and long-term stability.
    Jinghui Lyu (College of Chemical Engineering, Zhejiang University of Technology (ZJUT)) received his B.S. in 2006 and Ph.D degree in 2014 from ZJUT under the supervision of Prof. Xiaonian Li. He worked as a technology and engineering researcher (2006-2008) and as a postdoctoral fellow (2014-2016), contributing to the industrialization of several lab-scale catalytic technologies. From 2019 to 2020, he was a visiting scholar at Western University, Canada. His research focuses on heterogeneous catalysis, particularly the design and application of porous materials and supported metal catalysts for green chemical processes, including selective hydrogenation, oxidation reactions, and continuous flow catalysis. He received First Prize of the National Ministry of Education Technological Invention Award for green catalytic hydrogenation processes, Second Prize of Zhejiang Provincial Science and Technology Progress Award and the Second Prize of the China Chemical Society Science and Technology Progress Award for contributions to the continuous and miniaturized chemical processes. The green hydrogenation process and catalyst, along with the related research on continuous and miniaturized chemical processes have already been industrialized. He has led multiple national research projects in China and successfully transferred patented catalytic technologies to industrial practice.

Abstract:

Selective hydrogenation is crucial in various chemical processes and environmental applications, where precise control of reactivity and selectivity is essential for the efficient production of high-purity products. Single-atom catalysts (SACs), with atomically dispersed metal sites, could bridge homogeneous and heterogeneous catalysis and have emerged as a transformative platform for highly efficient selective hydrogenation with minimal use of critical raw materials as catalysts. This review explores the latest advancements in this cutting-edge area. Specifically, we analyze the structure-activity relationships, such as catalytic properties and mechanisms that determine the reactivity and selectivity of such catalytic systems. Furthermore, we discuss challenges, including stability, synthesis scalability, coordination environment tuning, atomistic modeling, and mechanistic insights, while identifying research opportunities for optimizing SACs performance. If these challenges are addressed, SACs hold the potential to revolutionize selective hydrogenation processes, offering sustainable and highly efficient catalytic solutions for industrial applications.
