Zn12O12 Cluster‐Based Materials with Enhancing Visible Light Absorption by Doping Alkaline Earth Metal Atoms: A First‐Principles Prediction

“…[17][18][19][20][21][22] Due to its superior chemical stability, excellent photoelectric properties, and ecofriendly nature, it has important potential applications in the field of photocatalysis. [23][24][25][26][27] However, the wide bandgap of ZnO prevents it from absorbing visible light and limits its photocatalytic effect. Therefore, enhancing its visible light absorption through bandgap reduction is an important contemporary issue.…”

Lutetium-Doped ZnO to Improve Photovoltaic Performance: A First-Principles Study

“…In light of the above discussion, it is important that an in-depth understanding of the fundamental properties of Lu-doped ZnO, such as charge transfer and spectral changes, be achieved from a theoretical perspective to gain insight into the mechanism of Lu doping effects on ZnO. Density functional theory (DFT) has a wide range of applications in computational materials science, providing a valuable standard tool for predicting the electronic and optical properties of materials. − In recent years, various researchers have utilized DFT to analyze the physical properties of ZnO-doped systems, such as electrical properties, optical properties, magnetic properties, etc. It is now well established from a variety of studies that the results of the DFT calculations for the material match the experimental results, validating the reliability of the DFT.…”

Doping regulates pyro-photo-electric catalysis to achieve efficient water splitting in Ba1−xSrxTiO3 through solar energy and thermal resources

“…1,2 Since Fujishima and Honda used n-type semiconductor TiO 2 to achieve the decomposition of aqueous hydrogen in 1972, 3 photoelectrochemical (PEC) water splitting based on semiconductors has been considered to be an important way to develop renewable hydrogen. In recent years, some n-type semiconductors such as WO 3 , 4 Fe 2 O 3 , 5 ZnO, 6,7 and BaTiO 3 8 have been used for photoelectrochemical water splitting. However, a limited light response range, low carrier separation and utilization efficiency are still the bottleneck of large-scale applications.…”
