Scientific Development Research

Metal catalysts are regarded as the "heart" of the chemical and chemical engineering fields, providing essential driving force for enhancing reaction efficiency, promoting green chemical engineering development, and optimizing product selectivity. This article systematically elaborates on the fundamental concepts, classification, and characteristics of metal catalysts. It addresses challenges in their application, such as the scarcity of precious metal resources and insufficient understanding of catalytic mechanisms. Furthermore, it highlights their extensive applications in key areas including petrochemicals, fine chemicals, environmental protection, and energy conversion. The future development trends are also discussed, with a focus on the core objectives of advancing toward high activity, high stability, high selectivity, and intelligent design. This work aims to provide theoretical reference and practical guidance for the development and application of novel, efficient metal catalysts.
