Herein, we first report a photocatalytic OCM using CO2 as soft oxidant for C2H6 production under mild conditions, where an efficient photocatalyst with unique interface sites is constructed to facilitate adsorption and activation, while concurrently boosting CH4 dissociation. As prototype, the Au quantum dots anchored on oxygen‐deficient TiO2 nanosheets are fabricated, Au‐Vo‐Ti activation collectively disclosed by in situ Kelvin probe force microscopy, quasi X‐ray photoelectron spectroscopy...

A new liquid crystalline dithienothiophene dimer cap-functionalized with 3,4,5-tris-n-dodecyloxyphenyl groups (1) has been synthesized. The absorption spectrum blue-shifts 7 nm, while the fluorescence red-shifts 95 nm in thin film respect to that solution, suggesting H-aggregate formation may occur and molecules are cofacially aligned solid state. Compound 1 self-organized into highly ordered, long-range 2-dimensional nanopatterns on oriented pyrolytic graphite; their structures were...

We used solvent−vapor treatment methods to determine nanoscale phase separation and thus tailor the charge mobility of poly(3-hexylthiophene)/fullerene (P3HT/C60) blend films. The nanowires obtained by chloroform vapor are rich in C60, whereas 1,2-dichlorobenzene (DCB) P3HT. treated blends offer far superior hole transport than untreated blends, which is attributed a three-dimensional network containing C60 or P3HT nanowires. Meanwhile, electrically bicontinuous morphology realized...

It has been proven that the raw wastewater, secondary effluent and even reclaimed water may have toxic effects on aquatic organisms. In present study, fractionation procedures combined with bioassays using luminescent bacteria were conducted to identify fractions contributed acute long-term toxicity of municipal wastewater. Solid phase extraction was used divide dissolved organic matter from wastewater into three fractions, including non-polar, medium-polar polar fraction. Among these...

Developing sustainable routes for the synthesis of zeolites is still a vital and challenging task in zeolite scientific community. One typical examples aluminosilicate EU-1 zeolite, which not very efficient environmental-unfriendly under hydrothermal condition due to use large amount water as solvent. Herein, we report route without solvent first time. The physicochemical properties obtained are characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM),...

As early as 1988, Yamamoto and colleagues demonstrated the first example of an asymmetric carbonyl-ene reaction aldehydes using organoalumnium complex (Tetrahedron Lett. 29, 3967). Subsequently, a large body work on this has appeared with particular focus glyoxolates substrates. In present study authors apply chiral N,N′-dioxide-nickel(II) to wide range glyoxal derivatives well various aryl aliphatic alkenes. A very number examples is provided demonstrate scope generality system. Products...
