Pt-based nanocatalysts are irreplaceable for proton exchange membrane fuel cells (PEMFCs), while the low reserves and high cost of Pt severely impede their commercialization. Tremendous efforts have been devoted to reduce the amount of precious metals and improve their electrocatalytic performance at the same time. Nanocatalysts with a hollow interior possess a large active area, high catalytic activity, good stability, and significantly reduce the amount of noble metal. The synthesis methods for their preparation are various, wherein the galvanic replacement reaction without additional procedure to remove the core, without the functionalization to the template surface and with ease of control, is the main method to prepare hollow structural nanocatalysts. We review the recent developments of hollow Pt-based nanocatalysts synthesized by the galvanic replacement reaction. The further challenges and developments of hollow Pt-based nanocatalysts are also discussed.
