Enhanced photoelectrocatalytic performance for degradation of dimethyl phthalate over well-designed 3D hierarchical TiO/Ti photoelectrode coupled dual heterojunctions.

A novel A/R-TiO NSs/NRs photoelectrode was constructed through electrodeposition of anatase TiO nanosheets (A-TiO NSs) with highly exposed {001} facet onto the 1D upright rutile TiO nanorods (R-TiO NRs). At first, A/R-TiO NSs/NRs exhibited enhanced adsorption of dimethyl phthalate (DMP) due to the specific recognition between Lewis acid sites of {001} facet and Lewis basic DMP. NH-TPD and Py-IR revealed that the Lewis acidity on the {001} facet of A-TiO NSs was much stronger than that of R-TiO NRs, demonstrating superior adsorption capacity to DMP.

Analysis on the difference of skin surface lipids during blue light therapy for acne by lipidomics.

Acne is a chronic inflammatory skin disease of the sebaceous glands of the hair follicles, caused by a variety of factors and tends to recur, causing skin damage and psychological stress to patients. Blue light (415nm) is a popular physical therapy for acne, however, studies on the effects of blue light on skin surface lipids (SSL) have not been exhaustively reported. So, we want to investigate the difference in SSL before and after acne treatment with blue light and to reveal the potential mechanism of acne treatment with blue light from the lipid level.

construction of 3D TiO photoelectrode with multilevel facet heterojunctions towards the efficient removal of bisphenol A.

An innovative three-dimensional (3D) TiO2 photoelectrode with multilevel facet heterojunctions (FHs) is rationally designed based on in situ 1D rutile TiO2 nanorods with top {111} facets on a Ti mesh substrate. The 3D configuration composed of nanosheets and nanorods is provided with large specific area. The stepped band structure of the multilevel FH gives further impetus to spatial charge separation.

Efficient photocatalytic removal of phthalates easily implemented over a bi-functional {001}TiO surface.

It is stubborn to remove the lowly concentrated phthalic acid esters (PAEs) that usually coexist with other highly concentrated but low-toxic pollutants in municipal sewage. Herein, we report a novel strategy for completely removing the PAEs over a bi-functional {001}TiO surface (with highly exposed {001} facet), which not only serve as functional sites to specifically adsorb the target PAEs pollutants, but also contribute to an enhanced oxidation ability. The adsorption behavior of PAEs on {001}TiO is analyzed deeply through kinetic experiments combining with in situ ATR-FTIR spectroscopy and theoretical calculations.
