Kinetic Study and Equilibrium Isotherm Analysis of Nickel (II) Adsorption onto Alginate-SBA-15 Nanocomposite

The present work was undertaken to evaluate the feasibility of nickel (II) removal from aqueous solution by adsorption onto a biopolymer adsorbent. The adsorbent was prepared using modification of mesoporous silicate SBA-15 with alginate biopolymer (alginateSBA-15) by encapsulation method. Morphological structure of the obtained nanocomposite adsorbent was characterized by XRD, scanning electro...

Hydrogen and oxygen adsorption stoichiometries on silica supported ruthenium nanoparticles

Treatment under H2 at 300 °C of Ru(COD)(COT) dispersed on silica yields 2 nm ruthenium nanoparticles, [Rup/SiO2], according to EXAFS, HRTEM and XPS. H2 adsorption measurements on [Rup/SiO2] in the absence of O2 show that Ru particles adsorb up to ca. 2 H per surface ruthenium atoms (2H/Rus) on various samples; this technique can therefore be used to measure the dispersion of Ru particles. In co...

Silica-Supported Palladium-Based Catalysts for Clean Synthesis

Research into supported palladium complexes is described. The complexes are immobilised on porous silica supports using both grafting and templated sol-gel techniques. The resultant complexes are efficient catalysts for various C-C bond forming reactions, including Heck, Suzuki and allylic substitution. The catalysts are stable and can be easily recovered and reused, making them suitable for cl...

Silica-Supported Palladium Particles with Infrared Reflection-Absorption Spectroscopy

The coadsorption of nitric oxide and carbon monoxide on Pd( loo), Pd( 11 l ) , and a model silica-supported palladium catalyst has been investigated with infrared reflection-absorption spectroscopy (IRAS) in the temperature range 100-500 K. The palladium surfaces were in equilibrium with a 1 X l P Torr equimolar mixture of CO and NO during the FT-IRAS studies. The structure and coverage of the ...
