Trapping of BTX compounds by SiO2, Ag–SiO2, Cu–SiO2, and Fe–SiO2 porous substrates

Chemosphere, 2010
Adsorption isotherms of BTX aromatic hydrocarbons (benzene, toluene, and p-xylene) on pristine (SiO2) and metal-doped (Ag-SiO2, Cu-SiO2 and Fe-SiO2) mesoporous and microporous substrates were measured and interpreted. These adsorbents were synthesized by the sol-gel procedure and their BTX sorption isotherms were obtained by the gas chromatographic ...

Reduction processes in Cu/SiO2, Co/SiO2, and CuCo/SiO2 catalysts

Catalysis Today, 2012
Abstract Cu/SiO 2 , Co/SiO 2 , and bimetallic CuCo/SiO 2 catalysts have been synthesized and their reduction behavior characterized by TPR, in situ XRD, and in situ XANES. In Cu/SiO 2 , a two step reduction process, CuO → Cu 2 O → Cu 0 , occurred. Two forms of the intermediate Cu 2 O with different degrees of reducibility were observed. Addition

Preparation of (Ni–B)/SiO2, Ni/SiO2 and NiO/SiO2 nanocomposites

Journal of Non-Crystalline Solids, 2003
Abstract In this work we report composites of nickel–boron (Ni–B)/SiO 2 , Ni 3 B/SiO 2 , Ni/SiO 2 and NiO/SiO 2 . As precursor of the nickel compounds, we used nanometric amorphous Ni–B alloy particles. The nanometric Ni–B particles were prepared by aqueous chemical reduction and studied by transmission electron microscopy (TEM), differential ...

The structure of CaO–SiO2 and PbO–SiO2 glasses

Physics and Chemistry of Glasses: European Journal of Glass Science and Technology Part B, 2022
Whereas the cybotactic theory and thermodynamic modelling have proved invaluable tools in understanding the structures and properties of alkali silicate glasses, questions have been raised as to their validity for alkaline earth and related glasses such as PbO–SiO2.
