ABSTRACT: Photocatalytic CO2 reduction by H2O and/or H2 reductant to selective fuels over Cu-promoted In2O3/TiO2 photocatalyst has been investigated. The samples, prepared via a simple and direct sol-gel method, were characterized by XRD, SEM, TEM, XPS, N2 adsorption-desorption, UV–vis diffuse … Continue reading →

Abstract: Global economic development intensifies the consumption of fossil fuels which results in increase of carbon dioxide (CO2) concentration in the atmosphere. The technologies for carbon capture and utilization to produce cleaner fuels are of great significance. However, phototechnology provides … Continue reading →

ABSTRACT: Photocatalytic CO2 methanation using H2O vapors and/or H2 reductants over nickel (Ni) and indium (In) promoted TiO2 nanocatalysts has been investigated. The physical–chemical characteristics of the catalysts, prepared through a sol–gel method with different Ni and In doping levels, … Continue reading →

ABSTRACT: The side products of biomass and bio-fuel industry have shown potential in producing carbon catalyst. The carbon cryogel was synthesized from lignin-furfural mixture based on the following details: 1.0 of lignin to furfural (L/F) ratio, 1.0 of lignin to … Continue reading →

ABSTRACT: There are many advantages associated with the use of hydrogen as clean fuels, thus there is a need to search for good hydrogen adsorbents. Activated carbon (AC) from various sources has been tested as hydrogen adsorbents, with the exception … Continue reading →

Abstract: Gas phase dehydration of glycerol to acrolein over a series of supported HSiW on ZrO2 and nano-sized gAl2O3 catalyst has been investigated. The characterization results revealed that impregnation of g-Al2O3 nanoparticles increased the specific surface area, pore diameter, and … Continue reading →

ABSTRACT: The photocatalytic reduction of CO2 with H2 over nickel (Ni) and indium (In) co-doped TiO2 nanocatalysts in a monolith photoreactor has been investigated. The structure and properties of catalysts, prepared via modified sol–gel method with different metal-doping levels, were … Continue reading →

Abstract: Experimental and theoretical studies were performed to evaluate the existence of internal and external mass transfer limitations in the gas phase glycerol dehydration to acrolein over supported HSiW catalyst. In the experimental method, the internal and external diffusions were … Continue reading →

ABSTRACT: The study on immobilized titania (TiO2) nanoparticles semiconductor on stainless steel mesh for photocatalytic conversion of CO2 and CH4 has been investigated. Properties of commercial and calcinated photocatalysts on mesh surface were characterized using UV–vis spectra, BET, FESEM and … Continue reading →
