Valuable information about the local environment of the aluminum nucleus can be obtained
through 27 Al Nuclear Magnetic Resonance (NMR) parameters like the isotropic chemical …

The hydrocarbon era1 began at the end of the 19th century, as a result of the discovery of oil
fields in the United States and together with the development of internal combustion …

To solve the aggregation problem of TiO 2 nanomaterials and improve the catalytic
efficiency, F-doped TiO 2/exfoliated bentonite (TF/EB) composite was prepared by …

The objective of this work is to investigate the surface acidity of γ-Al2O3 after modification
and its application in reducing coke formation in the fluid catalytic cracking (FCC) process. γ …

Recently, efforts have been made to synthesize large-pore, multidimensional zeolite
frameworks as a basis for new catalysts to improve various hydrocarbon conversions. A new …

Amorphous materials—magnesium oxide fluoride with hydroxy groups—of high surface
area were prepared for the first time by a soft sol–gel method involving initial fluorination and …

Solid-state NMR methods have been used to determine the mechanism for the fluorination
reaction of CHClF2 on alumina. The initial stages of fluorination lead to the formation of …

Nano-Ga/Al-ZSM-5 zeolites are synthesized by the in situ isomorphous substitution method
(I-series) and a secondary synthesis method in a Ga (NO3) 3/NH4F solution (S-series). The …

Nanomaterials are increasingly being used to improve the properties and functions of
common building materials. A new type of self-cleaning cement incorporating TiO 2 …
