Photodegradation of Rhodamine B over Biomass-Derived Activated Carbon Supported CdS Nanomaterials under Visible Irradiation
A family of new composite materials was successfully prepared through the deposition of as-synthesized CdS nanomaterials on lotus-seedpod-derived activated carbon (SAC). The SAC supports derived at different activation temperatures exhibited considerably large surface areas and various microstructures that were of great importance in enhancing photocatalytic performance of CdS@SAC composite mat...
متن کاملBiofuel Production and Kinetics Study of Catalytic Microwave Pyrolysis of Douglas Fir Pellet over Activated Carbon Supported Metal Catalyst
The presented study aims to improve the quality of bio-oils by catalytic upgrading of pyrolysis bio-oil from microwave pyrolysis of biomass using transition metal modified activated carbon (AC) catalyst. A central composite experimental design (CCD) was used to optimize the reaction conditions for high quality bio-oil production. The effects of reaction temperature and reaction time on product ...
متن کاملSelective catalytic reduction of sulfur dioxide by carbon monoxide over iron oxide supported on activated carbon
The selective reduction of sulfur dioxide with carbon monoxide to elemental sulfur was studied over ACsupported transition-metal oxide catalysts. According to the study, Fe2O3 /AC was the most active catalyst among the 4 AC-supported catalysts tested. By using Fe2O3 /AC, the best catalyst, when the feed conditions were properly optimized (CO/SO2 molar ratio = 2:1; sulfidation temperature, 400 ◦...
متن کاملConversion of biomass-derived sorbitol to glycols over carbon-materials supported Ru-based catalysts.
Ruthenium (Ru) supported on activated carbon (AC) and carbon nanotubes (CNTs) was carried out in the hydrogenolysis of sorbitol to ethylene glycol (EG) and 1,2-propanediol (1,2-PD) under the promotion of tungsten (WOx) species and different bases. Their catalytic activities and glycols selectivities strongly depended on the support properties and location of Ru on CNTs, owning to the altered me...
متن کاملSynergistic effect between defect sites and functional groups on the hydrolysis of cellulose over activated carbon.
The chemical oxidation of activated carbon by H2 O2 and H2 SO4 is investigated, structural and chemical modifications are characterized, and the materials are used as catalysts for the hydrolysis of cellulose. Treatment with H2 O2 enlarges the pore size and imparts functional groups such as phenols, lactones, and carboxylic acids. H2 SO4 treatment targets the edges of carbon sheets primarily, a...
