Unusual energy storage and charge retention in Co-based metal–organic-frame…
Abstract. In this communication, we explore the cobalt based metal–organic-frameworks (Co-MOF) as a promising material for supercapacitors. The doctor bladed Co-MOF film exhibits a good pseudocapacitor behavior with the specific capacitance up to 206.76 F g-1. The electrochemical redox switching is reversible perfectly for a long run which leads to the loss of only 1.5% in capacitance fo…

Abstract: Nanocarbon/polyaniline (PANI) composites were prepared by in situ polymerization of aniline on carbon blacks (CB), carbon nanotubes (CNTs) and graphene nanosheets (GNSs). The GNS/PANI composite has the highest PANI content with high specific capacitance, low internal resistance as well as improved cycling stability and rate capability. Of the three, the GNS/PANI composite shows bett…

Abstract. Nitrogen-doped microporous carbons (N-MCs) were prepared by the carbonization of the polyvinylidene fluoride (PVDF)/melamine mixture without chemical activation. The electrochemical performance of the N-MCs was investigated as a function of PVDF/melamine ratio. It was found that, without additional activation, the N-MCs had a high specific surface area (greater than 560 m2/g) beca…

Abstract. Nano-porous oxide layers on the surface of 302-type stainless steel were synthesized by galvanostatic anodization process carried out at two current densities, 7 and 15 mA cm-2 for the time periods of 15 and 30 min. A relatively thinner (~300 nm) and compact oxide layer formed when anodization was performed at a current density of 7 mA cm-2. However, with increase in anodization…
