First-principles calculations were carried out to explore the surface energies and electronic properties of α-Fe2O3 surface slabs. Further, to enhance the photocatalytic activity of Fe2O3, an alternative effective strategy was to examine Fe2O3-based heterostructures.

Electrons in HOMO consisted of O2p from TiO2 could be directly excited to LUMO composed by the hybridized orbital from GLM and TiO2 under irradiation. The well-separated electron–hole pairs induced an enhanced photocatalytic activity of TiO2/GLM.

We have investigated the effect of uniform plane strain on the electronic properties of monolayer 1T-TiS2using first-principles calculations. With the appropriate tensile strain, the material properties can be transformed from a semimetal to a direct band gap semiconductor.

Surface energies of strained Cu surfaces were studied systematically using first-principles methods. Results showed that the strain-stabilization of Cu surface was anisotropic and strongly related to the strain distribution. This strain-induced approach could be used as an effective way to engineer the surface energies of metals.
