The Effect of Fe-Loading and Calcination Temperature on the Activity of Fe/TiO2 in Phenol Degradation
In this research work, iron modified titanium dioxide photocatalyst was synthesized by the sol-gel method. The catalyst is characterized by FT-IR, XRF, and TGA techniques. Since the activity of Fe/TiO2 is highly affected by the loading of Fe, our major purpose of this work was focused on the role of this factor. Moreover, the effect of calcination temperature, which was also of h...

متن کاملRoom Temperature Oxidation of Al-Cu-Fe and Al-Cu-Fe-Cr Quasicrystals
We have investigated formation of oxides on quasicrystalline and crystalline alloy surfaces of similar composition, in different oxidizing environments. This includes a comparison between a quaternary orthorhombic approximate of Al-Cu-Fe-Cr quasicrystal and the ternary AI-Cu-Fe quasicrystalline and crystalline phases. We noted that each sample showed the following common trends: preferential ox...
متن کاملHexavalent chromium removal from a simulated wastewater using Fe(II) modified bentonite
Background and Objective: Hexavalent chromium is reported to be highly toxic, mutagenic and carcinogenic; hence treatment of water and wastewater contaminated with this element by low-cost and environmentally friendly methods is of great importance. Therefore the aim of present study was to evaluate the efficiency of Fe(II) modified bentonite for hexavalent chromium removal from a simulated was...
متن کاملA hierarchical Fe/ZSM-5 zeolite with superior catalytic performance for benzene hydroxylation to phenol.
We report the one-step synthesis of a highly active hierarchical Fe/ZSM-5 zeolite catalyst with a strongly improved lifetime in the selective hydroxylation of benzene to phenol with nitrous oxide; compared to the best Fe/ZSM-5 catalyst, the turnover number after 24 h on stream is almost four times higher.
