Development of Nano and Supramolecular Materials

2D materials are ideal for constructing flexible electrochemical energy storage devices due to their great advantages of flexibility, thinness, and transparency. We have also focused on 2D materials, i.e. metal oxide (MO), metal hydroxide (MOH), metal (M), graphene oxide (GO) and reduced graphene oxide (rGO) nano sheets. We have aimed at development energy devices and catalysis by using 2D and its hybrid materials.
