Visible-Light Photocatalysis with Mullite-Type Bi2(Al1- xFex)4O9: Striking the Balance between Bandgap Narrowing and Conduction Band Lowering
(American Chemical Society, 2018-09)
The rich crystal chemistry of mullite-type Bi2M4O9 (M = Fe, Al, Ga) offers multiple potential applications. In particular, the strong absorption of visible light shown by Bi2Fe4O9 has led to an influx of research on its ...
Unraveling the quantum dynamics origin of high photocatalytic activity in nitrogen-doped anatase TiO2: time-domain ab initio analysis
(Royal Society of Chemistry, 2020-12)
A wide bandgap and short-lived charge carrier constitutes two major issues for restricting anatase titanium dioxide (TiO2) photocatalytic activity in the ultraviolet light region of the solar spectrum. Interestingly, ...
Light emission from hydrogenated and unhydrogenated Si-nanocrystal/Si dioxide composites based on PECVD-grown Si-Rich Si oxide films
(Institute of Electrical and Electronics Engineers, 2006-12)
Hydrogenated and unhydrogenated Si-nanocrystal/Si dioxide (Si-nc/SiO2) composites were obtained from SiyO1-y (y=0.36, 0.42) thin films deposited by plasma-enhanced chemical vapor deposition. The unhydrogenated composites ...
Robust edge states induced by electron-phonon interaction in graphene nanoribbons
(American Physical Society, 2018-07-17)
The search of new means of generating and controlling topological states of matter is at the front of many joint efforts, including band-gap engineering by doping and light-induced topological states. Most of our understading, ...
Photocatalytic and biocidal activities of novel coating systems of mesoporous and dense TiO2-anatase containing silver nanoparticles
(Elsevier, 2014-10)
Here we describe the development of novel nanostructured coating systems with improved photocatalytic and antibacterial activities. These systems comprise a layer of SiO2 followed by a layer of mesoporous or dense TiO2-anatase, ...
