This paper provides a comprehensive overview of the unique physical and chemical properties and structures of graphene. It delves into the exceptional electronic and mechanical properties of graphene that make it a promising material for various applications. The paper particularly focuses on the use of graphene in supercapacitors and sensing techniques, specifically gas sensors. In the realm of energy storage, the paper elucidates how the high surface area and excellent conductivity of graphene contribute to the superior performance of graphene-based supercapacitors. It further explores the mechanism of charge storage in these devices, highlighting the role of pore sizes in graphene sheets on capacitance. In the context of gas sensors, the paper discusses how the sensitivity of graphene's electronic properties to its surrounding environment enables its use in detecting different gases. The paper concludes with a discussion of the challenges and future prospects in harnessing the potential of graphene in these applications.
