Unveiling the biointerfaces characteristics and removal pathways of Cr(Ⅵ) in Bacillus cereus FNXJ1-2-3 for the Cr(Ⅵ)-to-Cr(0) conversion.

Although less toxic than hexavalent chromium, Cr (Ⅲ) species still pose a threat to human health. The Cr (Ⅵ) should be converted to Cr (0) instead of Cr (Ⅲ), which is still involved in biological detoxification filed. Herein, for the first time, it was found that Cr(Ⅵ) can be reduced into Cr(0) by Bacillus cereus FNXJ1-2-3, a way to completely harmless treatment of Cr(Ⅵ).

Selective Bonding Effect of Heterologous Oxygen Vacancies in Z-Scheme CuO/SrFeTaO Heterojunctions for Constructing Efficient Interfacial Charge-Transfer Channels and Enhancing Photocatalytic NO Removal Performances.

An interfacial structure is crucial to the photoinduced electron transport for a heterostructure photocatalyst. Constructing an interfacial electron channel with an optimized interfacial structure can efficiently improve the electron-transfer efficiency. Herein, the rapid electron-transfer channels were built up in a CuO/SrFeTaO heterojunction (CuO/SFTO) based on the selective bonding effect of heterologous surface oxygen vacancies in the SFTO component.

CoAl-layered double hydroxide nanosheets as an active matrix to anchor an amorphous MoS catalyst for efficient visible light hydrogen evolution.

CoAl-layered double hydroxide nanosheets (CoAl-NSs) could serve as an active matrix to effectively anchor amorphous MoSx nanoparticles with high dispersion and the formation of an additional active "CoMoS" phase. The resulting CoAl-NSs/MoSx catalyst showed 13 times higher H2 evolution activity than free MoSx nanoparticles from an erythrosin B-triethanolamine (ErB-TEOA) system under visible light.

Thiomolybdate [MoS] nanocluster: a molecular mimic of MoS active sites for highly efficient photocatalytic hydrogen evolution.

Thiomolybdate [MoS] nanoclusters, as a molecular mimic of MoS edge sites, showed high efficiency in catalyzing photochemical H evolution from a molecular system of Ru(bpy)Cl-ascorbic acid (HA) under visible light irradiation (≥420 nm), providing a turnover number of 1570 and an initial turnover frequency of 335 h for H evolution based on the [MoS] catalyst.
