Oxidation State is the net charge that is carried by an atom due to the presence of extra electrons or the absence of its electrons. So, the charges denote the number of bond pairs it can make with others. The oxidation state of a molecule is the sum of the oxidation states of the ...
36,37or CH3I, while previous energy-dispersive spectroscopy19and X-ray photoelectron spectroscopy38results show that the atomic ratio of I to Pb for the beam-induced decomposition product is ~2, suggesting it to be PbI2instead of CH3I. Thus, the C–H bend signal in the final byproduct lik...
the total number of possible atomic configurations is given by 2n, wherenis the number of sites labeled by 12345678, i.e., resulting on 28 = 256 possible configurations for each alloy. However, the 256 atomic configurations can be organized in\(J=22\)symmetry equivalent classes ...

The standard formula for 2DPs can be represented as (A′)m(A)n−1BnX3n+1, where A’ is a bulky organic cation (such as an aliphatic or aromatic alkylammonium) that functions as a spacer between the inorganic sheets, and n is the number of inorganic layers held together. The ...
number of Cu2+in the double six-membered ring (6MRs). Such copper species contribute to a high NH3-SCR activity. Nevertheless, all materials show comparable activity in NH3-SCR up to 350 °C. Above 350 °C, NO conversion decreased for Cu-SSZ-13(2–4) due to side reaction of NH3...
N and M represent the number of the measured Ψ–Δ pairs and the fitting parameters, respectively and σΨexp and σ△exp represent the standard deviations of Ψ and Δ experimental data points, respectively. In the equation, the prefactor comprises 2N due to the inclusion of the two ...
The isolated VO4 units consist of one terminal V=O bond and three bridging V-O-Ti bonds, as shown in Figure 1a. As the coverage increases, the number of V-O-V bridges per V increases. In practical application, the vanadium species mainly exists in the form of polyvanadate, as shown ...
1015cm−3acceptor concentration implies that the generation rate of photo-generated carriers does not change with acceptor densities under the incident of the same photon number39. With increasing the acceptor doping concentration, the Fermi energy level of the hole decreases and henceVocincreases, ...
From the molecular design point of view for the NH3-SCR catalyst, the denitrification catalyst needs to have suitable acid-base and redox properties23,24. There are a large number of hydroxyl structures on the surface of SBA-15 MMS. Doping with Al can increase the acidity of the molecular ...
