Only the third type of electrons could initiate the hydrogen evolution reaction. As an auxiliary ingredient, a cocatalyst considerably inhibits the first two behaviors of electrons, thereby protecting the electrons from participating in reduction reactions.(1)...
The migration of photogenerated electrons and holes in the wall of g-C3N4 NTs was accelerated in reverse to bypass recombination center in an external magnetic field to improve the photocatalytic activity. The critical thickness of g-C3N4 NTs wall is 72 nm for separating and impelling the ...

in which i, η, α, n, F, i0, T, and R respectively stand for the current density, overpotential, transfer coefficient, number of electrons exchanged, Faraday constant, exchange current density, temperature, and gas constant. One can simplify Eq. (10) on the basis of the anodic/cathodic...
(e−) on the surface of the photocatalyst to become ‘excited’ in the valence band (VB), causing them to move to the conduction band (CB). Simultaneously, a positive hole (h+VB) is formed on the valence band. Electrons and holes are excited and migrate to the surface of ...

In recent years, nanostructured TMDs with a large number of exposed active edge sites have been proved to be one of the most competitive candidates for HER. Compared with other TMD structures, such as nanosheets and nanoflowers, QDs with a diameter of less than 20 nm show more edge sites...
Allen electronegativity is defined as the average one-electron energy of the valence shell electrons for the ground state free atoms [44]. Thus, the values of the Allen electronegativity can be obtained from the spectroscopic data. The variations of Allen electronegativity mismatch for HEAs are 8...
