Facile synthesis of heteroatom doped graphene nanosheets is one of the recent trends in the development of energy storage materials like supercapacitors. Phosphorus doped graphene sheets (P-GNS) have been prepared using electrochemical method (EC), which is the most emerging technique for large scale synthesis. X-ray diffraction studies of as-electrochemically phosphorus doped graphene nanosheets (EC-P-GNS) synthesized show a shift towards lower 2h values due to functionalized graphene sheets. Scanning electron microscopy analysis of EC-P-GNS shows folded and twisted type graphene nanosheets and the average sheet thickness was measured to be 40 nm. High resolution-transmission electron microscopy depth profile confirms the presence of few layer transparent graphene with twisted type sheets. Fourier transform-infra red analysis of EC-P-GNS confirms the presence of functional groups in the doped graphene sheets. X-ray photoelectron microscopy analysis of EC-P-GNS shows 0.68 % phosphorus atomic doping which confirms the P-doping in graphene nanosheets. The electrochemical performance was analyzed using EC-P-GNS and shows good cycle performance compared to graphite. The electrochemical charge/discharge curves of EC-P-GNS give a high specific capacitance (Csp) of 290 F g -1 along with high energy density 43.75 Wh kg -1 . Based on the above merits including higher Csp, we hope that our EC-P-GNS would be a promising material for super capacitors. Further, the prepared single pot electrochemical anodic erosion strategy provides easy scale up for all heteroatoms doped graphene nanosheets synthesis.
The present study reports the synthesis of CeO2 nanoparticles using Fusarium solani. The biosynthesized CeO2 nanoparticles were subjected to different characterization techniques and also showed potential antibacterial and antibiofilm activities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
