Zeolites possessing large specific surface areas, ordered micropores, and adjustable acidity/basicity have emerged as ideal supports to immobilize metal species with small sizes and high dispersities. In recent years, the zeolite‐supported metal catalysts have been widely used in diverse catalytic processes, showing excellent activity, superior thermal/hydrothermal stability, and unique shape‐selectivity. In this review, a comprehensive summary of the state‐of‐the‐art achievements in catalytic applications of zeolite‐supported metal catalysts are presented for important heterogeneous catalytic processes in the last five years, mainly including 1) the hydrogenation reactions (e.g., CO/CO2 hydrogenation, hydrogenation of unsaturated compounds, and hydrogenation of nitrogenous compounds); 2) dehydrogenation reactions (e.g., alkane dehydrogenation and dehydrogenation of chemical hydrogen storage materials); 3) oxidation reactions (e.g., CO oxidation, methane oxidation, and alkene epoxidation); and 4) other reactions (e.g., hydroisomerization reaction and selective catalytic reduction of NOx with ammonia reaction). Finally, some current limitations and future perspectives on the challenge and opportunity for this subject are pointed out. It is believed that this review will inspire more innovative research on the synthesis and catalysis of zeolite‐supported metal catalysts and promote their future developments to meet the emerging demands for practical applications. Recent research progress on the catalytic applications of zeolite‐supported metal catalysts for diverse reactions (e.g., hydrogenation reactions, dehydrogenation reactions, oxidation reactions, hydroisomerization, and selective catalytic reduction of NOx with ammonia) are comprehensively summarized. Some current limitations and future perspectives on challenges and opportunities for this subject are also highlighted.
