It was suggested that basicity and weak acidity are intrinsic features of the clay structure, while medium and strong acidities are induced by the exchangeable cation.doi:10.1016/j.tca.2006.07.019A. AzzouzD. NistorD. MironA.V. UrsuR. Hausler...

Fluorine-doped tin oxide (TEC15, Hartford, IN) was pat- terned through a wet-etching method (H2 evolution reaction between zinc powder and hydrochloric acid), followed by an overnight base bath-soaking (5 wt% NaOH in ethanol). A compact TiO2 layer was deposited by a spray pyrolysis of ...
Herein, three types of model Ce2(SO4)3-CeO2 catalysts with distinct interfaces are constructed to reveal the effect of acid-redox interaction on NH3-SCR performance. That is, SO42-/CeO2-VS (vapor sulfation of ceria) with strong acid-redox interfacial contact, SO42-/CeO2-WI (wet ...
Before fixation in methanol:acetic acid (3:1), leaves were incubated for 2,5 h in 2 mmol/l 8- hydroxyquinoline. Fixed plant ma- terial was macerated in an enzyme mixture consisting of 2 % (w/v) cytohelicase (Sigma), 2 % (w/v) cellulase from Aspergillus niger (Sigma-Aldrich), 4...
(TPD) curve for the Fe–Mn/Al-SBA-15 catalyst and Fe–Mn/SBA-15 catalyst. The desorption peaks at 100–250, 280–330, and 380–500 °C were attributed to desorption of physisorbed NH3, NH3bound to weak Brønsted acid sites, and NH3bound to strong Brønsted and Lewis acid sites,...
The doping of Ce significantly enhanced NH3 adsorption from weak, medium and strong acid sites, reduced the crystallinity of α-Fe2O3 in ARM, optimized the specific surface area and broadened the active temperature window, which increased the NOx conversion rate by an average of nearly 20% ...
Non-covalent interactions (NCIs) are present in complexes formed between two or more Lewis acids and Lewis bases. In fact, those interactions are commonly named by the Lewis acid [1]. On the one hand, a Lewis base (LB) or a LB motif is associated with a region of space where there ...
