The ECSA of Pt-Ru/MWCNT (566.63 ± 2.9 cm2/mg) was higher than Pt/MWCNT (484.38 ± 2.2 cm2/mg), possibly was due to the formation of homogeneous Pt-Ru NPs and stronger bonding of MWCNTs with Pt-Ru NPs. In addition, the onset potential of Pt-Ru/MWCNT (0.105 ± 0.02 V) ...
[duplicate] We know that methanol is slightly more acidic than water, because water's ability to donate a proton as an acid is reduced due to extensive hydrogen bonding. [...] [...] It is very clear that methoxi.. Distillation of methanol and water - Temperature Change We tried the ...
The activity is mainly affected by the bonding strength of COads, and the binding energy of COads can be regulated by the electronic effect.(2)M-COads + 2OH−→ M + CO2 + H2O + 2e− Alternatively, OHads can be generated either on or around noble sites, and COads could react with...
This is the result of the chemical nature of the molecules, their sizes, and the relative strengths of the dispersive interactions in small pores in comparison with hydrogen bonding to surface functional groups.doi:10.1080/00268970110110815SALAME, ISSA I....

In the sorption and pervaporation processes, the polymer active centers of a membrane are able to interact with components of liquid mixture by means of van der Waals, dipole–dipole, and ion–dipole forces, or through hydrogen bonding30. Quantitatively, the polymer‒penetrant interaction can be...
the O atom of the hydroxy group and the empty, anti- bonding orbital localized on the Si dimer. The strength of the orbital interaction can be estimated by the perturbative analysis of the Fork matrix in the NBO basis, and the energy ...
FTIR was used to gain bonding information and associated functional groups of the synthesized materials in the 450–4000 cm−1 range, Fig. 1 (b). For all the samples, the broad and strong peaks at 3447 and 1632 cm−1 are attributed to the OH stretching vibration and bending mode, res...
