Particularly, the number of carbon atoms bonded to the nitrogen atom affects the pKa of the amine site, resulting in greater CO2 binding strength. In addition, the proportions of carbamate anion, ammonium cation, and (bi)carbonate species in the solvent vary according to various factors such as...
Surface strategies for catalytic CO2 reduction: from two-dimensional materials to nanoclusters to single atoms. Chem. Soc. Rev. 48, 5310–5349 (2019). This article summarizes the surface modification strategies for low-dimensional catalysts applied in heterogeneous photocatalytic CO2 reduction. Article ...
1d, the reduction peaks in H2-TPR were attributed to the reduction of the Mo-O species on Mo2N. It was noticed that even at 950 °C, the H2 consumption was still found, demonstrating that part of the oxygen atoms was strongly coordinated with Mo atoms and were very hard to be ...
This clearly indicates the presence of basicity on H-form acidic zeolites. The number of lattice oxygens of H-form zeolites located around Al in (AlO4) units was affected by the environment of the central Al atoms in the framework of the zeolites. Consequently, the number of base sites ...
The carbon atoms could also coordinate with the surface oxygen atoms to prevent the formation of oxygen vacancies. To verify the superior CO2RR catalytic activity of oxidative In sites, the corresponding reaction free energy diagram of In2O3 and In was depicted in Fig. 1h30. The adsorption ...
Role of Cu oxide and Cu adatoms in the reactivity of CO2 on Cu(110). Angew Chemie Int Ed. 2024;63: e202405554. https://doi.org/10.1002/anie.202405554. Article Google Scholar Jia H, Du T, Li Y, Wang H, Yue Q, Zhou L, Wang Y. Preparation of catalyst for CO2 hydrogenation ...
Valence-shell electron pair repulsion is a theory based on the number of electrons surrounding the central atom.Answer and Explanation: Carbon dioxide has a linear molecular geometry. The central atom of carbon dioxide is carbon, which is doubly bonded to the two oxygen atoms. It is......
SCE. PyH+'s procliv- ity to regain its aromaticity drives HT from the hydridic C- H bond of PyH2 to the carbon atoms of CO2, HCOOH and OCH2 to form reduced products and to recover the aro- matic PyH+ (or Py) catalyst. This mirrors the aromatization driving force several of us...
Calculated electrostatic potentials of (c) In2O3 (111) and (d) Nb2O5 (100) slabs. The yellow, green, and purple spheres represent In, Nb, and O atoms, respectively. e The formation of In2O3/Nb2O5 S-scheme heterojunction, and the proposed charge transfer and separation mechanism. ...
resulting in hybrid properties between the two materials making it possible to navigate through the descriptor space. Multi-metallic catalysts could be formed by doping a substrate with a different metal e.g. in the form of single atoms73, forming an overlayer74, forming homogeneously mixed high ...
