متن کاملReduced graphene oxide-TiO2 nanocomposite as a promising visible-light-active photocatalyst for the conversion of carbon dioxide
Photocatalytic reduction of carbon dioxide (CO2) into hydrocarbon fuels such as methane is an attractive strategy for simultaneously harvesting solar energy and capturing this major greenhouse gas. Incessant research interest has been devoted to preparing graphene-based semiconductor nanocomposites as photocatalysts for a variety of applications. In this work, reduced graphene oxide (rGO)-TiO2 ...
متن کاملPalm Shell-based Activated Carbon for Removing Reactive Black 5 Dye: Equilibrium and Kinetics Studies
Activated carbon derived from biomass waste, namely palm shell, was evaluated as a potential adsorbent for the removal of Reactive Black 5 dye (RB5) from an aqueous solution. This work focused on the equilibrium isotherms and the kinetics of the adsorption process. Batch adsorption tests were conducted to determine the effects of various parameters, such as contact time, RB5 concentration, adso...
متن کاملApplication of TiO2–zeolite as photocatalyst for photodegradation of some organic pollutants
Immobilization of catalysts on the surface of some inert supports makes therecovering step easier. Because of the specific physicochemical properties, zeolites are good candidate as catalyst supports. In this study, zeolite X was synthesized by natural kaolin and TiO2 was incorporated into zeolite phase by impregnation method. Degradation of Safranin Orange, methylene blue and 2,4–di...
متن کاملEvaluation of efficiency of copper-nickel ferrite nanoparticles loaded onto multi-walled carbon nanotubes in activation of peroxymonosulfate for degradation of reactive black dye 5 from aqueous solutions
Background and Aim: The development of industry has recently led to the release of 2 × 105 tons of colored wastewater into the environment. The presence of these solutions due to their toxicity and carcinogenic potential can be a threat to human health. The aim of this study was to investigate the efficiency of MWCNTs-CuNiFe2O4 nanocomposite in activating peroxymonosulfate (PMS) for degradatio...
