Improving the sintering resistance of noble metal particles in industrial catalysis and inhibiting the loss of noble metal particles in liquid phase catalytic reaction are the key factors to improve the stability of catalysts. At this report, Prof. Guozhu Chen firstly gave a brief introduction to his preliminary work. Then Prof. Guozhu Chen gave a detailed introduction to their lab's recent papers. These papers were mainly on Pt/CeO2 and CeO2/Pd@MIL-53(Al). Finally, Prof. Guozhu Chen also patiently answered questions from teachers and students.
