Modeling of supramolecular ordering and physiochemical properties in cyclohexane-ethanol mixtures

Article Abstract:

The quasichemical model of the nonideal associated solution (QCNAS) was used to analyze the excess thermodynamic functions and permittivity of cyclohexane-ethanol mixtures in the entire range of compositions and in a wide temperature range. The results show that a relatively low fraction of cyclic nonpolar alcohol aggregates essentially influences the properties of cyclohexane-ethanol solution as whole and, in particular dielectric properties of dilute solutions.

Reforming of oxygenates for H(sub 2) production: Correlating reactivity of ethylene glycol and ethanol on Pt(111) and Ni/Pt(111) with surface d-band center

Article Abstract:

The dehydrogenation and decarbonylation of ethylene glycol and ethanol was studied using temperature programmed desorption on Pt(111) and Ni/PT(111) bimetallic surfaces. The reforming activity was correlated with the d-band center of the surface and displayed a linear trend for both ethylene glycol and ethanol, with activity increasing as the surface d-band center moved closer to the Fermi level.

Highly active TiO(sub 2)N photocatalysts prepared by treating TiO(sub 2) precursor in NH(sub 3)/ethanol fluid under supercritical conditions

Article Abstract:

The N-doped TiO(sub 2) layer was prepared by pretreating the TiO(sub 2) precursor in the NH(sub 3)/ ethanol fluid under supercritical, denoted as TiO(sub2)N(SC). The activity of the TiO(sub 2)N(SC) first increased and then decreased with the increase ind the N-content.
