Nitrogen-doped graphene with high nitrogen level via a one-step hydrothermal reaction of graphene oxide with urea for superior capacitive energy storage
Nitrogen-doped graphene nanosheets (NGS) with the nitrogen level as high as 10.13 atom% were synthesized via a simple hydrothermal reaction of graphene oxide (GO) and urea. N-doping and reduction ofExpand
Structure and adsorption properties of sewage sludge-derived carbon with removal of inorganic impurities and high porosity.
Purified sludge carbon (PSC) with removal of inorganic 'impurities' (Si, Al, etc.) is prepared from sewage sludge and is superior to SC and comparable to commercial activated carbon for rhodamine B and phenol adsorption capacity. Expand
From coconut shell to porous graphene-like nanosheets for high-power supercapacitors
Sheet-like graphitic carbon with a porous structure can provide low-resistant pathways and short ion-diffusion channels for energy storage, and thus is expected to be an excellent material forExpand
Carbothermal synthesis of ordered mesoporous carbon-supported nano zero-valent iron with enhanced stability and activity for hexavalent chromium reduction.
This study suggests that nZVI/OMC has the potential for remediation of heavy metal pollution in water and has the advantage in removal efficiency and reusability in comparison to nZ VI/C, OMC and n ZVI. Expand
Effects of simultaneously doped and deposited Ag on the photocatalytic activity and surface states of TiO2.
It could be found that the impurity bands and abundant surface states were introduced into the interfacial layer of TiO2 because of Ag simultaneously doping and depositing, which could improve the absorption capability for visible light of the photocatalysts. Expand
Preparation and Characterization of Stable Biphase TiO2 Photocatalyst with High Crystallinity, Large Surface Area, and Enhanced Photoactivity
Stable porous TiO2 photocatalysts, with higher photocatalytic activity than Degussa P25, were synthesized via a hydrothermal process using cetyltrimethylammonium bromide as the template, followed byExpand
Photoinduced charge property of nanosized perovskite-type LaFeO3 and its relationships with photocatalytic activity under visible irradiation
Abstract In this paper, ABO 3 -type perovskite LaFeO 3 nanosized photocatalysts were synthesized by a sol–gel method, using citric acid (HOOCCH 2 C(OH)(COOH)CH 2 COOH) as complexing reagent and La(NOExpand
Ordered mesoporous black TiO(2) as highly efficient hydrogen evolution photocatalyst.
The facile synthesis of ordered mesoporous black TiO2 (OMBT) materials, which exhibit excellent photocatalytic hydrogen evolution performances and can extend the photoresponse from ultraviolet to visible and infrared light regions and exhibit a high solar-driven hydrogen production rate. Expand
Cost-effective large-scale synthesis of ZnO photocatalyst with excellent performance for dye photodegradation.
Zinc oxide with excellent photocatalytic performance for the photodegradation of dyes (superior to Degussa P25 TiO(2)) could be easily prepared in large quantity by direct calcination of zinc acetateExpand
Effect of surface species on Cu-TiO2 photocatalytic activity
Abstract The Cu-TiO 2 nanoparticles with different Cu dopant content were prepared by sol–gel method. The structure of the as-prepared catalysts and the surface species of Cu-TiO 2 were determinedExpand
