Pressure-induced structural phase transition and vacancy filling in titanium monoxide TiO up to 50 GPa
TL;DR: In this article, the authors demonstrate that high-pressure could be a clean strategy to tune the vacancies in oxides with a high cationic vacancy content, which can enhance the mobility of atoms in the lattice under pressure and lead to the pressureinduced amorphization and recrystallization.

Enhanced polysulfide conversion through metal oxide-support interaction in MnOx/MXene
Congying Song,Congying Song,Qing Yan,Tianran Zhang,Haibin Lin,Hualin Ye,Qiaofeng Yao,Shengliang Zhang,Yang Li,Guiling Wang,Jim Yang Lee +10 more
TL;DR: In this paper, MnOx/MXene composites were used as a model system using the chemical activity of MXene to invoke an interfacial interaction with manganese oxide.
Journal ArticleDOI
Chlorinating CeO2 at surface oxygen vacancies to promote their selectivity in oxidative dehydrogenation of propane to propene
TL;DR: In this article, the authors demonstrate that HCl treatment can controllably chlorinate CeO2 at surface oxygen vacancies and tightly regulate the content of surface oxygen vacancy (OS) structure-property studies reveal that the decreased ratio of OS quasi-linearly promotes the C3H6 selectivity in oxidative dehydrogenation of propane (ODHP).

Carbon quantum dots functionalized g-C3N4 nanosheets as enhanced visible-light photocatalysts for water splitting
Gen Li,Jiaming Huang,Niuniu Wang,Jiale Huang,Yanmei Zheng,Guowu Zhan,Qingbiao Li,Qingbiao Li +7 more
TL;DR: In this article, the carbon quantum dots (CQDs) functionalized g-C3N4 (CCN) by a simple thermal polymerization method, and the CQDs serving as a photosensitizer can enlarge the absorption range of visible light of composite material.
Journal ArticleDOI

Electrochemical Photolysis of Water at a Semiconductor Electrode
Akira Fujishima,Kenichi Honda +1 more
TL;DR: Water photolysis is investigated by exploiting the fact that water is transparent to visible light and cannot be decomposed directly, but only by radiation with wavelengths shorter than 190 nm.
Journal ArticleDOI
