The development of highly active and long life Pt-based nanocatalysts is an urgent research task in the field of energy catalysis.Core-shell structured Pt catalysts can improve the utilization rate of Pt atom，which provides an effective route to achieve the above goal.The catalytic activity of Pt-based core-shell nanocatalysts is highly sensitive to the lattice strain，while the stability is closely related to the interaction of the core-shell interface.However，it is extremely difficult to manipulate the lattice strain of Pt shells in a controllable manner，making it difficult to optimize the catalytic activity through manipulating lattice strain.The existing approaches for preparing Pt-based core-shell nanocatalysts are difficult to accomplish good stability of the catalysts while maximizing the utilization of Pt metal.Approaches that can tune strains in a systematic way and construct strong interactions between core and Pt shell are the key to realize the practical application of Pt-based core-shell nanocatalysts.The strategy for improving the performance of Pt-based core-shell nanocatalysts was discussed，including shell thickness adjustment，morphology control，and strain manipulation.This work would provide guidance for the development of highly efficient fuel cell catalysts.
