An ordered mesh of palladium with a thickness of about 3 nm was synthesized by a solution-based oxidative etching. The ultrathin palladium nanomeshes have an interconnected two-dimensional network of densely arrayed, ultrathin quasi-nanoribbons that form ordered open holes. The unique mesoporous structure and high specific surface area make these ultrathin Pd nanomeshes display superior catalytic performance for ethanol electrooxidation (mass activity of 5.40 Am g and specific activity of 7.09 mA cm at 0.8 V vs. RHE). Furthermore, the regular mesh structure can be applied to support other noble metals, such as platinum, which exhibits extremely high hydrogen evolution reaction (HER) activity and durability.
通过基于溶液的氧化蚀刻合成了厚度约为 3nm 的钯有序网格。超薄钯纳米网具有相互连接的二维密集排列的超薄准纳米带网络，形成有序的开口孔。独特的介孔结构和高比表面积使这些超薄 Pd 纳米网在乙醇电氧化中表现出优异的催化性能（在 0.8V 相对于 RHE 下，质量活度为 5.40Amg 和比活度为 7.09mAcm）。此外，规则的网格结构可用于支撑其他贵金属，如铂，其表现出极高的析氢反应 (HER) 活性和耐久性。
