Abstract：The utilization of natural energy to catalyze the conversion of low energy storage materials into clean fuels, catalytic reforming, hydrogenation, and oxidation to synthesize organic compounds, and improve the high added value of products, is currently an effective way of energy utilization. Ruthenium catalysts are inexpensive, have good reaction activity, selectivity, and stability, and play a significant role in fields such as petroleum refining, fine chemicals, and new energy. Combined with specific catalytic applications, supported ruthenium based composite catalysts are often prepared by coating ruthenium on the surface of materials, blending doping, coprecipitation, sol gel, hydrothermal doping, high-temperature blending melting and roasting reduction. Based on the practical applications of ruthenium based catalysts in recent years, elaborates the preparation methods and catalytic performance of supported catalysts were elaborocted, and the specific applications of supported ruthenium was summarized based on catalysts in ammonia synthesis, electrocatalytic hydrogen production, hydrogenation reactions, oxygen evolution reactions, and oxidation reactions.
