Two paths diverged: Alcohol and aldehyde oxidation on NiOOH is achieved through two mechanisms. One involves chemical hydrogen atom transfer to Ni3+ sites while the other involves electrochemical hydride transfer to Ni4+ sites. It is examined how these pathways impact the oxidation of HMF and its oxidative intermediates, which functional group of HMF is oxidized first, and how tuning the potential of the Ni(OH)2/NiOOH couple affects the contributions of these two mechanisms.

NiOOH 上氢原子转移和氢化物转移对 HMF 的电化学氧化以及 NiOOH 组成的影响



两条路径不同:NiOOH 上的醇和醛氧化是通过两种机制实现的。一种涉及化学氢原子转移至Ni 3+位点,而另一种涉及电化学氢化物转移至Ni 4+位点。研究了这些途径如何影响 HMF 及其氧化中间体的氧化、HMF 的哪个官能团首先被氧化,以及调节 Ni(OH) 2 /NiOOH 电对的电位如何影响这两种机制的贡献。
