White lead: A new naturally occurring 2D material

Abstract Atomic scale crystallographic structures of a quantum crystals depend on substrate, interfacial strain, defects, surface functionalities etc., which make it challenging to precisely control. To achieve high quality material, UHV conditions are prerequisite, makes costly. Naturally occurring 2D materials have tremendous significance in this regard. White lead, having weak interlayer coupling and easily found natural ores never been exfoliated. Keeping the novelty mind, one needs explore its physical as well chemical behaviour look out for appropriate applications. We first time, therefore, sonochemically exfoliated white established behaviour. also blended with graphene oxide explored gas sensing applications hybrid system be very selective NH 3 gas. naturally material; has time sensing.
