New phenothiazine-based organic dyes with two anchoring groups at 3,7 positions and systematic alkyl chains on nitrogen were prepared. Their TiO(2)-Pt composites showed excellent photo-catalytic activities in visible light-induced water splitting. Interestingly, phenothiazine dyes with longer alkyl chains showed better stability in catalytic systems.

New Zr(IV)- and Hf(IV)-based metal-organic framework photocatalysts, termed VNU-1 and VNU-2 (where VNU = Vietnam National University), were synthesized and their resulting structures fully characterized. By employing a highly π-conjugated linker, namely 1,4-bis(2-[4-carboxyphenyl]ethynyl)benzene, the optical absorption properties were effectively red-shifted into the visible light region. This ...

We report one dimensional (1D) MoS2 nanosheet/porous TiO2 nanowire hybrid nanostructures synthesized by a simple hydrothermal method, leading to an enhanced specific surface area (66 m(2) g(-1)). These 1D hybrid nanostructures as co-catalysts exhibit high activity in visible light photocatalytic hydrogen evolution reaction (HER) with an enhanced hydrogen generation rate of 16.7 mmol h(-1) g(-1).

[Cu5(OH)4(H2O)2(A-α-SiW9O33)2](10-) (1) was tested as the first copper-containing polyoxometalate catalyst for O2 production via visible light-driven water oxidation. Multiple experiments confirm that 1 is an active and dominant catalyst during water oxidation.

The spin-polarized plane-wave pseudopotential method, based on density-functional theory, has been used to calculate the electronic band structures and the optical absorption spectra of nitrogen-doped and oxygen-deficient anatase TiO2. The calculated results are in good agreement with our experimental measurements. These ab initio calculations reveal that the optical absorption of nitrogen-dope...

A highly efficient and chemoselective method for the synthesis of diaryl disulfides is developed via a visible light-promoted coupling of readily accessible arenediazonium tetrafluoroborates and CS2. This practical and convenient protocol provides a direct pathway for the assembly of a series of disulfides in an environmentally friendly manner with good to excellent yields.

A novel multiresponsive function of monoclinic BiVO(4) has been put forward for the first time, and loosely packed monoclinic BiVO(4) nanoellipsoids with many exposed crystal planes have been designed and synthesized in order to improve their smart multiresponses to visible light, trace gas and temperature.

A circular holographic display that consists of phase-only spatial light modulators is used to reconstruct images in visible light from digital holograms recorded under infrared (10.6 μm) illumination. The reconstruction yields a holographic digital video display of a three-dimensional ghostlike image of an object floating in space where observers can move and rotate around it.

A mild and efficient one-pot visible light-induced method has been developed for the allylic oxidation. The oxidation of allylic systems has played a prominent role in this context as possibly the most widely applied C–H functionalization, owing to the utility of enones. The allylic C–H oxidation is relatively simple and predictable, even on a preparative scale, because active species generated...

Previous works reported that linear optics could be used to observe sub-wavelength features with a conventional optical microscope. Yet, the ability to reach a sub-200 nm resolution with a visible light remains limited. We present a novel widely-applicable method, where particle trapping is employed to overcome this limit. The combination of the light scattered by the sample and by the trapped ...
