466930 Investigation of the Formation of Porous Boron Nitride and Its Application for Oil/Water Separation
This presentation will report the results of an in-depth investigation of the effects of the synthesis conditions on the formation of porous BN. Towards this goal, porous BN was synthesised via a bottom-up approach and then analyzed using a range of analytical techniques (i.e. N2 sorption, XRD, FT-IR, XPS, thermogravimetric analysis). It was found that the intermediate preparation had a large effect on the physical features of the resulting BN, and particularly its porosity with surface areas ranging from 400 to 1000 m2/g depending on the conditions. This dramatic change was assigned to the varying crystallinities of the intermediates which in turn impacted their thermal decomposition pattern and hence the formation of BN. Owing to it hydrophobic nature, BN can be used for the separation of oil and water. In order to provide a fundamental understanding of the nature of the interactions between hydrocarbons and the surface of BN, 2D BN nanosheets (BNNSs) were produced and molecular interactions were investigated using Scanning Tunnelling Microscopy (STM).
