Prussian blue-assisted one-pot synthesis of nitrogen-doped mesoporous graphitic carbon spheres for supercapacitors

Abstract

One-pot synthesis of nitrogen doped mesoporous graphitic carbon spheres with dispersed metal oxide nanoparticles using a single temperature treatment step serves as one of the big challenges in materials research.

Facile Synthesis Strategy from Sludge-Derived Extracellular Polymeric Substances to Nitrogen-Doped Graphene Oxide-Like Material and Quantum Dots

“…The textural property of N-GO was characterized by N 2 adsorption and desorption measurements. The N 2 adsorption/desorption isotherms of N-GO present a type-IV isotherm as the classification of the International Union of Pure and Applied Chemistry (Figure A). − The surface area calculated from the Brunauer–Emmett–Teller (BET) curve indicates a surface area of 71.424 m 2 g –1 and pore volume of 0.14 cm 3 g –1 (Figure B), which is similar to the reported values of GO . N-GO exhibits an average pore width of 8.02 nm, indicating that N-GO allows for the adsorption of accessible molecules onto the surface and into the pore.…”

Facile and environmentally friendly synthesis of ultramicroporous carbon spheres: A significant improvement in CVD method

“…Carbon spheres (CS) ranging in size from nanometers to micrometers have received considerable attention over the past decade due to their outstanding role in some applications such as energy storage and conversion, catalysis, gas adsorption and storage, drug and enzyme delivery, and water treatment [1][2][3]. So far, several pathways have been developed for the synthesis of CS, [4] including nanocasting with silica spheres as hard templates, [5] hydrothermal carbonization of carbohydrates [6], chemical vapour deposition (CVD) [7,8], modified Stöber synthesis [9], soft-templating methods [10][11][12], plasma [13],…”

Nitrogen–phosphorus doped graphitic nano onion-like structures: experimental and theoretical studies

“…They reported GNOs with diameters ranging from 200 to 600 nm. Graphitic materials have been doped with nitrogen, 18 boron, 19 sulfur, 20,21 beryllium, 22 and phosphorus. 23,24 The doping in graphitic materials can improve their electrochemical activity taking advantage of the different electronegativity of the dopants, which can polarize the adjacent atoms.…”
