Nitrogen doping has been an effective way to tailor the properties of graphene and render its potential use for various applications. Three common bonding configurations are normally obtained when nitrogen into graphene: pyridinic N, pyrrolic graphitic N. This paper reviews nitrogen-doped graphene, including synthesis methods introduce N characterization techniques examination configurations. Potential applications N-graphene also reviewed on basis experimental theoretical studies.
Abstract Electrochemical energy storage has emerged as one of the principal topics present‐day research to deal with high demands modern society. Accordingly, besides fuel cells and battery technologies, interesting challenging results have been observed in recent past, during materialization “supercapacitors” or “ultracapacitors”, which provoked a sharp increase inclination revisit this aspect renewable sustainable storage. Supercapacitor performances are largely dependent on electrode...
A three-dimensional interconnected graphene monolith was used as an electrode support for pulsed electrochemical deposition of platinum (Pt) nanoparticles. Pt nanoparticles with well-defined morphology and small size can be obtained by controlling electrodeposition potential time. Electrochemical characterization carried out to examine the electrocatalytic activity this monolithic towards methanol oxidation in acidic media. The results show that carbon material surface structure have a...

Abstract Dye‐sensitized solar cells (DSSCs) have gained increasing attention with regard to photovoltaic devices, because of their low cost and simple fabrication methods; they are mostly investigated in indoor light‐harvesting portable applications. The focus has been on three main parameters that is, lifetime, effectiveness. A DSSC consists four prominent components including a photoanode, photosensitizer, redox electrolyte, counter electrode. electrode is crucial component, which...
Rapid determination of trace antibiotics is critical for environmental monitoring and the ecosystem. In this study, a sensitive selective electrochemical sensor ciprofloxacin (Cip) detection by anodic stripping voltammetry Cu2+ designed. Zr(IV)-based metal–organic framework (MOF) NH2–UiO-66 reduced graphene oxide (RGO) composites are used as working electrodes, which have large surface area with porous structure high electrical conductivity. Because Cip can form stable composite due to...
Abstract Alongside rare‐earth metals, Ni, Fe, Co, Cu are some of the critical materials that will be in huge demand thanks to growth clean‐energy sector.
