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.

具有可调分支长度的多面支化镍纳米粒子，用于生物质的高活性电催化氧化。

控制具有高均匀性的纳米支化纳米粒子的形成是合成具有改进的活性和稳定性的纳米催化剂的主要挑战之一。利用立方核六角支化机制形成高度单分散的支化纳米颗粒，我们改变镍支化的长度。以生物质转化为例，延长镍分支及其高活性面覆盖率可以提高 5-羟甲基糠醛 (HMF) 的电催化氧化活性。
