Surface-chemical study of an aqueous mixture of alpha-sulfolauric acid salts with cationics

The physicochemical properties of an aqueous mixture of alpha-sulfolauric acid (H2LS) and its various salts, including sodium alpha-sulfolaurate (NaHLS), triethanolammonium alpha-sulfolaurate (TeAHLS) with a cationic surfactant, decyltrimethylammonium bromide (DeTAB), have been investigated. The surface activities of H2LS and its salts were enhanced greatly in the mixed systems; e.g. for a 1:1 mixed solution, the cmc and gammacmc can be reduced from 1.4 ¡Á 10-2 mol dm-3 and 45 mN m-1 to 5 ¡Á 10-4 mol dm-3 and 24 mN m-1 respectively. The effect of inorganic electrolytes (NaBr and HBr) on the surface activity and the molecular interactions between the two surfactants in the mixed adsorption layer and micelles have been studied systematically. It was found that the phase separation concentrations (PSCs) of the mixed surfactant solutions are greater than the cmcs. For 1:1 NaHLS-DeTAB solution, PCS/cmc = 3.2. It is also revealed that, unlike the common anionic-cationic mixture, e.g. C10H21SO4Na-DeTAB, the mixed micellar solution is thermodynamically stable up to 3 ¡Á cmc.

The surface activities of H2LS and its salts were enhanced greatly in the mixed systems; e.g. for a 1:1 mixed solution, the cmc and gamma(cmc) can be reduced from 1.4 x 10-2 mol dm-3 and 45 mN m-1 to 5 x 10-4 mol dm-3 and 24 mN m-1 respectively.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: N,N,N-Trimethyldecan-1-aminium bromide, you can also check out more blogs about2082-84-0

Efficient electroreduction of CO2 on bulk silver electrode in aqueous solution via the inhibition of hydrogen evolution

Electrochemical CO2 reduction provides a desirable pathway to convert greenhouse gas into useful chemicals. It is a great challenge to reduce CO2 efficiently in aqueous solution, especially on commercial bulk metal electrodes. Here, we report substantial improvement in CO2 reduction on bulk silver electrode through the introduction of ionic surfactant in aqueous electrolyte. The hydrogen evolution on the electrode surface is greatly suppressed by the surfactant, while the catalytic ability of silver towards CO2 reduction is maintained. The Faradaic efficiency for CO is greatly enhanced from 50% to 95% after the addition of this low-cost surfactant. This study may provide new pathways towards efficient CO2 reduction through the inhibition of proton reduction.
