In the coming year, we plan to build upon the success of last cycle by carrying out more hydrocarbon studies of this porous material NOTT-300 and one of its iso-structural framework materials, NOTT-302, which contains Indium metal centres. This study will include different loadings of C2D2, C2D4, C2D6 and CD4 to complete the comprehensive study of this hydrocarbon-host system. NPD data collected for different gas loadings is important to establish the detailed mechanism by which the adsorption sites are populated. This study is significant for the practical application of these materials to separate the mixture of hydrocarbons. In our experiment last cycle, we demonstrated not only the effectiveness of this method, but also the suitability of WISH for this type of experiment with its the low background and fast counting, which are essential for the location of gas adsorption sites.
