The lattice strain
Splet27. avg. 2024 · Abstract Lattice strain plays a critical role in regulating the electronic structure and improving the performance of catalysts. Here, Ir−IrO 2 /C catalysts with different iridium content are obtained by annealing Ir/C in air. The growth of IrO 2 on Ir nanoparticles can form a core–shell structure and introduces strain at their interface. http://www.paper.edu.cn/scholar/showpdf/NUz2kN4IOTD0IxeQh
