Palladium nanocrystals can be structurally evolved into metastable nanoporous palladium with catalytic activity toward ethanol electrooxidation. The resultant palladium structure has bimodal pore distribution and a large electrochemically active surface, and its catalytic activity can be enhanced through the structural evolution of palladium nanocrystals. The proposed method is simple and based on an easy process that excludes treatments in high temperature, high vacuum, or inert gas environments, and is thus suitable for mass production of palladium electrocatalyst.

钯纳米晶体可以在结构上演变成亚稳态纳米多孔钯，对乙醇电氧化具有催化活性。所得钯结构具有双峰孔分布和较大的电化学活性表面，通过钯纳米晶体的结构演化可以增强其催化活性。该方法简单且工艺简单，无需在高温、高真空或惰性气体环境中进行处理，因此适用于钯电催化剂的大规模生产。更多信息可以在 Nakanishi 等人的通讯中找到。
