This Master's thesis aims to document the research process into the synthesis of 2D AlPO4 via a liquid metal synthesis pathway. The synthesised 2D AlPO4 will then undergo qualitative and structural analysis, after which it will be characterised via advanced techniques to determine piezoelectric characteristics, as well as the exploration of the ability of the synthesised material to absorb heavy metals.
