Abstract
AbstractThe exploration of efficient and environmentally friendly oxidation method is highly desirable to overcome the critical problems of poor selectivity and heavy metal contamination for the fine chemicals industry. Herein, a self‐supported three‐dimensional (3D) SeNi5P4 nanosheet electrocatalyst was rationally designed and fabricated. Benefiting from the synergistic effect of aminoxyl radical and mesoporous SeNi5P4/graphite felt (GF), an excellent performance of ≥98% selectivity and 33.12 kg (m−3 h−1) space–time yield was obtained for sterol intermediate oxidation with the enhanced mass transfer effect of the continuous flow system. The doping of anionic selenium and phosphorus modulated the electronic structure of SeNi5P4, and the oxyhydroxides generated by surface reconstruction accelerated the turnover of 2,2,6,6‐tetramethyl‐1‐piperidine N‐oxyl (TEMPO), thereby enhancing the intrinsic electrocatalytic activity. A scale‐up experiment was conducted with stacked‐flow electrolyzer demonstrated the application potential. This work provided an efficient synergistic electrocatalytic strategy to facilitate rapid electron and mass transfer for electrochemical alcohol oxidation and highlighted the potential for practical electrosynthesis applications.
