Strain-Induced Photocatalytic H Production over BiVO in Pure Water without Any Cocatalyst.

In this study, BiVO nanosheets (BiVO-NS) were prepared by a facile hydrothermal method. It is found that sonication-induced strain can effectively promote the H production over BiVO-NS in the presence of pure water without any cocatalysts. With the assistance of the sonication, the H production over BiVO-NS is 1.

Characterization, stability and antioxidant activity of curcumin nanocomplexes with soy protein isolate and pectin.

Curcumin (Cur) has antioxidant, anti-inflammatory and other biological activities, but its poor stability, low water solubility and other defects limit the application. Herein, Cur was nanocomposited with soy isolate protein (SPI) and pectin (PE) for the first time and its characterization, bioavailability and antioxidant activity were discussed. The optimal encapsulation process of SPI-Cur-PE was as follow: the addition amount of PE was 4 mg, Cur was 0.

Amino-functionalized MIL-125(Ti) for photodenitrification of pyridine in fuels coordination activation by unsaturated Ti centers.

Due to their explicit structure, metal-organic frameworks (MOFs) have been supposed to be credible platforms to research the micro-mechanism of heterogeneous photocatalysis. In this study, amino-functionalized MOFs (MIL-125(Ti)-NH (denoted as MTi), UiO-66(Zr)-NH (denoted as UZr) and MIL-68(In)-NH (denoted as MIn)) with three different metal centers were synthesized and applied for the denitrification of simulated fuels under visible light irradiation, during which pyridine was used as a typical nitrogen-containing compound. The results showed that MTi had the best activity among the above three MOFs, and the denitrogenation rate increased to 80% after 4 h of visible light irradiation.

Spatial Separation of Electrons and Holes among ZnO Polar {0001} and {101̅0} Facets for Enhanced Photocatalytic Performance.

Spatial separation of electrons and holes is critical for improving their photocatalytic performance, which is ascribed to the suppressed photoinduced carriers' recombination among facets. In this work, the ZnO-Au-MnO heterogeneous nanostructure photocatalyst was prepared by photodepositing Au and MnO on the ZnO polar {0001} and {101̅0} crystal facets, respectively. The photocatalytic performance of ZnO-Au-MnO was higher than ZnO and ZnO-Au for the degradation of rhodamine B dye under UV light irradiation.

Spatial variation of volatile organic compounds and antioxidant activity of turmeric ( L.) essential oils harvested from four provinces of China.

The objective of this study was to investigate the spatial variation of volatile organic compounds and antioxidant activity of turmeric essential oils (TEOs) harvested from four provinces of China. The major chemical components of these TEOs were analyzed using headspace solid-phase micro-extraction gas chromatography-mass spectrometry. More than forty volatile organic compounds in TEOs were identified, which accounted for 82.
