In the recent decades, two dimensional materials have drawn interest in a variety of fields. Their unique characteristics and the ability to exfoliate them have opened new ways for advance technologies. In the renewable energy domain, the layered 2D material nickel oxyhydroxide (β – NiOOH) is known as one of the best catalysts for the sluggish oxygen evolution reaction (OER), one of the two reactions that occurs in water splitting for producing hydrogen. Whereas the bonds in the intralayer region are strong, the weak Van Der Waals forces between the layers could cause versatile orientations between the layers arising from harsh chemical environments. By using theoretical methods, our research aims to understand how these interlayer arrangements could affect the OER and the amount of energy needed to split water. We
will also demonstrate the effects of mechanical changes on a bilayer heterostructure which is composed of nickel oxyhydroxide and graphene.
