Confined water in Benzene Mesoporous Organosilica
In recent studies, we have shown that the physical properties of confined water, such as mobility and phase state, has a tremendous impact on the water-to-hydrate conversion in ordered mesoporous carbons[1]. Silica, however, is the basic component of rock where most hydrate is found. Therefore, we aim to study by INS the impact of silica polarity on the phase properties of confined water. To this end, we selected benzene mesoporous organosilica (BMO) because it is a model material that combines highly ordered pore structure with well-defined surface chemistry within cylindrical pores offering an ideal scenario to investigate confined fluids[2]. The water partially wets BMO due to the alternation between silanol and benzene groups on its surface[3]. This special feature dramatically changes the water behavior comparing to the well-known MCM-41 that exhibits merely silanol groups (uniform wetting). Therefore, we propose to measure in Lagrange: dry BMO and BMO loaded with water. Two water content will be carefully selected in order to ensure that water is in mesopores. [1] J. Phys. Chem.
