On the other hand, when pH is higher than the PZC of Cys-δ-FeOOH, the surface of Cys-δ-FeOOH is negatively charged, and more functional groups are available for metal cation binding due to deprotonation, resulting in the electrostatic attraction between in l-cystine on the surface of ...
Here, MII is a divalent cation, MIII is a trivalent metal cation, x is the molar ratio of the trivalent cation [MIII/(MIII + MII)], and An− is a gallery anion with charge n [4,5,6]. LDHs have received widespread attention in diverse applications, including in catalysis [7]...
This is in contrast to the prevailing view that cytochrome P-450 acts as a redox catalyst to generate an Fe(V)-oxo species or an Fe(IV)-oxo cation radical as the reactive intermediate. 展开 DOI: 10.1002/ijch.198800003 年份: 1987
8a). This can be explained by the fact that hydrous zirconia acts as both a cation exchanger and an anion exchanger (Clearfield et al., 1994). After adsorption, these peaks disappeared and two new characteristic peaks of P2s and P2p emerged, indicating that phosphate was adsorbed on the ...
In nanostructured oxides, the point defects concern the presence of dopant and/or the vacancies of cation or oxygen. In proportion to the number of defects, gap states are introduced by vacancy defects. Diffuse reflectance was used (BTFO/NFO ) nanocomposites to in study the optical properties ...

Hydrotalcites of formula Mg6(Al,Fe)2(OH)16(CO3)路4H2O formed by intercalation with the carbonate anion as a function of divalent/trivalent cationic ratio have been successfully synthesised. The XRD patterns show variation in the d-spacing attributed to the size of the cation. Raman and ...
Metallic iron (Fe0) has shown outstanding performances for water decontamination and its efficiency has been improved by the presence of sand (Fe0/sand) and manganese oxide (Fe0/MnOx). In this study, a ternary Fe0/MnOx/sand system is characterized for it
(OER), and the doping of Fe has been demonstrated to be an effective approach to improving the performance7,8. However, whether the activity could be further enhanced in a synergetic manner by incorporating other defects, such as anion and cation vacancies, has not been reported. We believe ...
