Carbon black-intercalated reduced graphene oxide electrode with graphene oxide separator for high-performance supercapacitor
We present a general study on a high performance supercapacitor based on intercalated reduced graphene oxide with carbon black nanoparticles. Graphene oxide sheets were synthesized by oxidation and exfoliation of natural graphite and were reduced using hydroiodic acid in the presence of carbon black nanoparticles. Graphene paper was fabricated by one-step procedure via simultaneous reducing and...
متن کاملMechanism of ion adsorption to aqueous interfaces: Graphene/water vs. air/water.
The adsorption of ions to aqueous interfaces is a phenomenon that profoundly influences vital processes in many areas of science, including biology, atmospheric chemistry, electrical energy storage, and water process engineering. Although classical electrostatics theory predicts that ions are repelled from water/hydrophobe (e.g., air/water) interfaces, both computer simulations and experiments ...
متن کاملFabrication of ultrathin graphene oxide-coated membrane with hydrophilic properties for arsenate removal from water
Terms and conditions of current drinking water quality standards, including reducing the maximum arsenic concentration from 50 μgl-1 to 10 μgl-1 and predicted stricter standards in future, reveals the necessity for development of new technologies. This study aimed to prepare and evaluate a new nanocomposite membrane using graphene oxide (GO) thin layer to remove arsenic (v) from water. To fabri...
متن کاملStrengthening of Graphene Aerogels with Tunable Density and High Adsorption Capacity towards Pb2+
Graphene aerogels (GAs) with high mechanical strength, tunable density and volume have been prepared only via soaking graphene hydrogels (GHs) in ammonia solution. The density and volume of the obtained GAs are controlled by adjusting the concentration of ammonia solution. Although volume of the GAs decreases with increasing the concentration of ammonia solution, its specific surface area maint...
متن کاملSupport effects in the adsorption of water on CVD graphene: an ultra-high vacuum adsorption study.
Experimental data for water adsorption on CVD (chemical vapor deposition) graphene/SiO2 and graphene/Cu studied under ultra-high vacuum (UHV) conditions are discussed, focusing on support effects and hydrophobicity. Under UHV, it seems that graphene wettability is inversely related to wetting properties of the support. Graphene is not transparent to water wetting on the supports studied here.
