摘要：
Paratacamite doped Polypyrrole (PDPpy) is synthesized by wet chemical method employing CuCl2 as oxidant. BET, optical and structural analysis revealed mesoporous polymer doped with [Cu-2(OH)(3)Cl]. Electrochemical analysis of PDPpy in 0.01 M H2SO4 indicated excellent hydrogen storage ability and steady hydrogen evolution kinetics. The maximum capacity of hydrogen storage is found be 59.1 mAh/g via galvanostatic charge/discharge experiments. Optical studies confirmed the stability of the PDPpy after HER. Plausible mechanism for hydrogen storage and evolution is deduced from H-1 NMR and XPS analysis. Analogous studies have been carried out in Polypyrrole (Ppy) synthesized using FeCl3 and Ammonium per disulphate (APS) oxidants to understand the ability of hydrogen storage in the absence of paratacamite.
