Controlling the formation of nanosized branched nanoparticles with high uniformity is one of the major challenges in synthesizing nanocatalysts with improved activity and stability. Using a cubic-core hexagonal-branch mechanism to form highly monodisperse branched nanoparticles, we vary the length of the nickel branches. Lengthening the nickel branches, with their high coverage of active facets, is shown to improve activity for electrocatalytic oxidation of 5-hydroxymethylfurfural (HMF), as an example for biomass conversion.
控制纳米尺寸分支纳米粒子的形成，使其具有高度的均匀性，是合成具有提高的活性和稳定性的纳米催化剂的主要挑战之一。我们使用立方核六方支化机制来形成高度单分散的分支纳米粒子，并改变镍支的长度。研究表明，延长镍支的长度可以增加活性面的覆盖率，从而提高电催化氧化 5-羟甲基糠醛（HMF）的活性，HMF 是生物质转化的一个例子。
