Abstract
AbstractBoth proton exchange membrane fuel cells and uranium‐based nuclear techniques represent two green and advanced energies. However, both of them still face some intractable scientific and industrial problems. For the former, established proton‐conduction materials always suffer one or another defect such as low proton conductivity, high activation energy, bad durability, or just small‐scale product; while for the later, there still lacks available adsorbent to selectively recover of UO22+ from concentrated nitric acid (>1 M) during the spent fuel reprocessing due to the deactivation of the adsorption site or the decomposition of adsorbent under such rigorous conditions. It is found that the above two issues can be well solved by the construction of sulfonic‐pendent vinylene‐linked covalent organic frameworks (COFs), since these COFs contain abundant sulfonic units for both intrinsic proton conduction and UO22+ capture through strong coordination fixation and vinylene linkage that enhances the stability up to 12 M nitric acid (one of the best materials surviving in 12 M HNO3).
