Distribution of the acid–base strengths of various ion-exchanged montmorillonites was assessed through thermal programmed desorption (TPD) of NH 3 and CO 2. Accurate acid–base measurements can be achieved via deconvolution of perfectly symmetrical peaks, under optimal carrier gas throughput and ...
However, acid-base neutralization also occurs. Such as, chicken is easily infected by Salmonella, which metabolizes protein to produce acidic H2S etc.(Chen et al., 2023, Lu et al., 2020, Rosniawati et al., 2021). This causes acid-base neutralization of the headspace gas, so evaluating ...
and density functional theory (DFT) calculations to address their intercage transfer and possible roles of BAS strength. The results presented in this study will provide the basis for the rational design of more efficient and robust Cu-zeolite catalysts for NH3-SCR. ...
Recently, great attention has been paid to Ceria-based materials for selective catalytic reduction (SCR) with NH3 owing to their unique redox, oxygen storage, and acid-base properties. Two series of bimetallic catalysts issued from Titan... M Jawaher,A Hanan,E Reinhard,... - 《Catalysts》 被...
Note, that signal strength is reduced in centromeric regions. Signals in centromeric regions are due to sequences occurring in association with both, CenH3 in the centromere and H3K9me2, e.g. sequences of Beetle4. The signals may be also due to the presence of H3K9me2 in active ...
(B-CeS), sufficient acid sites with strong intensity were generated on CeO2modified with surface sulfates (S-CeS). In addition, due to electron-withdrawing effect from S=O in sulfate species, NH3oxidation over S-CeS was greatly suppressed, providing an additional contribution to enhanced ...
Thus, the charge flow shifted from NH3 (a base) to OTX3 (an acid). The largest contribution was from the orbital interaction between Lp(N) and Molecules 2019, 24, 10 8 of 13 σ*X-O in 6-OXH3-fulvene···NH3 (X = Si and Ge), while it was from that between Lp(N) and σ...
[56] innovatively introduced metal chlorides, such as anhydrous MgCl2, NiCl2, MnCl2, and ZnCl2, into a binary Res/EG system to prepare ternary DESs, and the NH3capacity notably increased owing to the cooperating hydrogen bonding and Lewis acid–base interactions. In particular, the NH3absorption...
Answer to: Classify the compounds given below as a strong acid, weak acid, strong base, or weak base: Sr(OH)2 , HCN, HClO4, CsOH, NH3, H2SO3, HI...
Adding Pd meshed with C, N element to TiO2 based NFs might contribute to generation of Lewis acid sites and Brønsted acid sites, which have been recently shown to enhance NH3 adsorption-desorption ability; Pd NPs could increase the quantity of adsorbed O2 on the surface of TiO2 based NFs,...
