Dendritic silver self-assembly in molten-carbonate membranes for efficient carbon dioxide capture

In this work, the dendritic growth of silver within a supported molten-salt membrane was exploited to produce membranes with unparalleled carbon dioxide flux. Dendritic growth was evidenced using X-ray micro-CT and conductivity measurements. Multiple pore tubular membranes were fabricated, as well as randomly porous membranes. In both geometries, silver dendritic growth occurred and resulted in enhanced flux. A selection of the membranes provided agenda-setting carbon dioxide fluxes, and approached or bettered the permeance, selectivity and permeability requirements for economically-competitive carbon dioxide capture.<br>Look at the README file for description of data and processing etc.

本研究利用负载型熔盐膜（supported molten-salt membrane）内银的枝晶生长（dendritic growth）工艺，制备出具有前所未有的二氧化碳通量（carbon dioxide flux）的膜材料。通过X射线显微CT（X-ray micro-CT）与电导率测量，验证了枝晶生长现象的存在。本研究制备了多孔隙管状膜与随机多孔膜两类样品，在这两种膜结构中均发生了银枝晶生长，且该过程使二氧化碳通量得到显著提升。部分制备得到的膜材料展现出标杆性的二氧化碳通量，其透过率、选择性与渗透率均达到或优于具备经济竞争力的二氧化碳捕集应用的性能要求。
