Molecular geometry is the three-dimensional representation of a compound's structure based on the bond formed and lone pairs (nonbonding electrons). Valence-shell electron pair repulsion (VSEPR) and Lewis dot structure are theories involved in predicting the molecular geometry of a compound. Valence...

Photoelectrochemistry (PEC) presents a direct pathway to solar fuel synthesis by integrating light absorption and catalysis into compact electrodes. Yet, PEC hydrocarbon production remains elusive due to high catalytic overpotentials and insufficient sem

Therefore, the crystalline core-amorphous shell structure facilitates the charge carrier spatial separation, which enhances the excited-state Lewis basicity and acidity of the Ti(III)-[O]-Ti(IV)-OH, namely the ES SFLP, by the trapped electrons and holes. This ES SFLP not only enhances ...
This compound can be classified as a poly-cyclic poly-Frustrated Lewis Pair (FLP) system, as it presents more than one Lewis Acid/Lewis Base pair on its surface, making the capture of several carbon dioxide molecules possible. Two scenarios were considered to fully characterize the capture of ...
By evaluating the results of extended X-ray absorption fine structure (EXAFS), we found that Au-S bonding decreased over the course of the reaction and became imperceptible over ∼90 min of operation (Figures 3A and 3B). The Au-Au distance decreased from the initial Au2S during catalytic ...
