Abstract: In this study a monolith photoreactor was compared with a cell type for testing photocatalytic CO2 reduction with H2 as a reducing agent. The monolith channels were dip-coated with TiO2 nanoparticles and were characterized using XRD, SEM, BET and UV–Vis spectroscopy. The … Continue reading →

Abstract: In this study, the performance of montmorillonite (MMT) modified TiO2nanocomposites for photocatalytic CO2 reduction with CH4 in a continuous monolith photoreactor has been investigated. The MMT modified TiO2 nanocomposites were dip-coated over monolith channels and were characterized by XRD, SEM, TEM, XPS, … Continue reading →

Abstract: A series of Fe/HY zeolite catalysts with different FeCl3 weight percent (5, 10 and 15%) on HY zeolite have been synthesized in this study. All the catalysts were characterized by XRD, FESEM, N2 physisorption, FTIR, TGA, NH3-TPD and IR-pyridine. The performance … Continue reading →

Abstract: Indium (In)-doped titanium dioxide (TiO2) nanoparticles were synthesized using a controlled sol–gel method. The structures and properties of the catalysts were characterized by XRD, FE-SEM, TEM, XPS, BET, UV–vis and PL spectroscopy. Indium, present over the TiO2 in metal state, … Continue reading →

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 →
