Mesoporous nano Ni-Al2O3 catalysts were prepared by using Pluronic P123 (P123) and fatty alcohol polyoxyethylene ether (AEO-7) as structure directing agents (SDAs), applied for CO2 methanation in a continuously stirred tank reactor (CSTR). Compared with NiAl-A AEO-7 SDA NiAl-N without SDA, NiAl-P possesses ordered mesopores, high Ni dispersion, large metal surface area amounts of adsorbed CO2, ...

In this research, Carbon-doped TiO2 nano-photocatalyst is synthesized via sol-gel technique and photo-catalytic degradation of phenol has been studied under ultraviolet and visible light irradiation in a fluidized bed reactor. Various techniques are used to characterize TiO2 nano-photocatalyst such as X-Ray Diffraction, Fourier transform infrared spectroscopy,  Energy Disp...
