Two dimensional materials are class of materials that demonstrated interesting properties of high surface area, high electrical, optical, and mechanical properties compared to the base materials. Among the two dimensional materials, graphene, MXene, and metal organic frame works (MOF) demonstrated a high activity in the different energy storage/conversion devices. We have successfully prepared these materials and investigated their activity in different types of fuel cells and supercapacitors. In microbial fuel cells (MFCs), doping of the carbon brush based anode resulted in improving the electrical conductivity and surface that resulted in 10 times increasing in the power output compared to the bare carbon brush. 

Also modifying the cobalt electrode with graphene resulted in a superior activity towards methanol oxidation in direct methanol fuel cell. Composite of the MOF and MXene were used to modify the electrodes of the supercapacitor resulted in a significant increase in the energy density of the device. Furthermore, two dimensional metal chalcogenides were successfully prepared and demonstrated a superior activity in direct urea fuel cell and high energy density supercapacitor. The outstanding performance of these materials was related to the high surface area, high porosity, and excellent mass transfer and charge transfer properties.
