原文开头
Bromine-mediated electrochemical propane dehydrogenation by self-assembled ionic liquid-SnO2 hollow spheres Jiarui Yang1*, Zhihao Pei1, Bo-Chao Ye2, Wen-Hao Li3, Han Yan4, Deyan Luan1, Dingsheng Wang2*, Xiong Wen (David) Lou1* Conventional thermal propane dehydrogenation (PDH) faces several notable drawbacks, including high energy requirements, coking-induced catalyst deactivation, and the need for product separation. An electrocatalytic approach, using self-assembled ionic liquid (IL)–tin dioxide (SnO2) hollow spheres as the electrocatalyst, enables efficient PDH at ambient temperature. In this process, bromopropane formed in the anolyte from propane reacts with hydroxyl anions from the cathode to yield propene. The propene selectivity exceeds 98%, and the continuous production of high-purity (>99%) propene gas from the anolyte eliminates the need for downstream separation. …
