An FTIR study of zeolite theta-1

Article Abstract:

The acidic properties of two samples of zeolite Theta-1 (Si/Al = 25 and 50) were studied as the propensity to form hydrogen bond with several probes. The adsorption of small molecules at a nominal temperature of 77 K leads to bathochromic shifts in OH stretching vibration of the Si(OH)Al groups close to the medium-pore zeolites observed with ZSM-5 and H-MOR.

Templated synthesis of carbon materials from zeolites (Y, beta, and ZSM-5) and a montmorillonite clay (K10): physical and electrochemical characterization

Article Abstract:

Combinations of zeolite and montmorillonite clay templates with acrylonitrile, furfuryl alcohol, pyrene and vinyl acetate precursors are used for the synthesis of low-temperature carbon materials. The results indicate that the formation of the SEI layer during lithiation is affected by the NaY zeolites that impart properties on the carbon materials.

A theoretical investigation of the methylation of methylbenzenes and alkenes by halomethanes over acidic zeolites

Article Abstract:

The reactivity of chloromethane, bromomethane, and iodomethane over acidic zeolite catalysts was probed, using the methylation of ethene, propene, and toluene as model reactions. A weak trend in reactivity was found among the halomethanes, indicating the following order of reactivity: MeI > MeBr > MeCl.

Methane, Methylation
