Synergetic Effect of Fe2O3 Doped-CeO2 Nanocomposites Prepared via Different Techniques on Photocatalytic Desulfurization of Heavy Gas Oil

Autor: Manar S. Radwan, Wael A. Aboutaleb, Ahmed M. A. El Naggar, Shymaa S. Medany, Mohamed R. Shehata

Publikováno v: Arabian Journal for Science and Engineering.

The photocatalytic performances of three Fe2O3–CeO2 nanocomposites were investigated toward the sulfur removal from a petroleum heavy gas oil (HGO) sample. The three composites were prepared by three different routes namely; auto-combustion, post-p

Increased production of hydrogen with in situ CO

Autor: Mohamed S A, Darwish, Ahmed M A, El Naggar, Asmaa S, Morshedy, Nils, Haneklaus

Publikováno v: Environmental science and pollution research international. 28(3)

One of the chief challenges in hydrogen production through the photocatalytic splitting of water is to employ an efficient photocatalyst that has an absorption edge at the range of long wavelengths. In this study, composite structures made of differe
