MnO2 nanosheets grown on N

Abstract This work reports the design of layered MnO2 nanosheets grown on conductive frame of N-doped agaric derived porous carbon (N-) for asymmetric supercapacitors. The extremely high specific surface area of N- (2250 m2 g−1) provides a large contact area for MnO2. Meanwhile, the good retention of the unique three-dimensional pore structure of N- can effectively shorten the

Preparation and Characterisation of Polypyrrole

Polypyrrole (PPy) has been widely used as a sensing material in many studies as PPy gives out noticeable reactions towards varieties of vapours of acids, bases, alcohols, alkanes, and chemical warfare agent (CWA) simulants. However, due to dispersion and mechanical properties limitation, PPy in nanoparticles (PPy NPs) has been introduced. The combinations between PPy NPs and nanosized
