n- and isoalkane adsorption mechanisms on zeolite MCM-22
Article Abstract:
Low-coverage adsorption properties of linear and branched alkanes on zeolite MCM-22 were determined using the chromatographic technique at temperatures between 420 and 540 K. The results revealed that adsorption enthalpy and entropy of linear alkanes vary in a nonmonotonic way with carbon number and the adsorption behavior of alkanes was rationalized on the basis of the pore geometry.

Synthesis of high-quality MCM-48 mesoporous silica using Gemini surfactant dimethylene-1,2-bis(dodecyldimethylammonium bromide)
Article Abstract:
High quality ordered cubic mesoporous silica is prepared through the S(super +)I(super -) route by using the Gemini surfactant with the short spacer group as structure-directing agent and sodium silicate as precursor. The findings indicate that the pore structure of the resulting mesoporous silica belonged to the cubic structure.

Transition metal modified TiO2-loaded MCM-41 catalysts for visible- and UV-light driven photodegradation of aqueous organic pollutants
Article Abstract:
A number of transition metal incorporated MCM-41 mesoporous molecular sieves with Si/Me = 80 have been synthesized by a hydrothermal method. The catalytic performances have been correlated with the UV-vis spectrum of each synthesized catalyst to reveal the specific role played by each metal ion.
