Magnetic Chitosan/ZrO Composites for Vanadium(V) Adsorption while Concurrently being Transformed to a Dual Functional Catalyst.

Spent adsorbents for recycling as catalysts have drawn considerable attention due to their environmentally benign chemistry properties. However, traditional thermocatalytic strategies limit their applications. Here, we developed an enhanced photocatalytic strategy to expand the range of their applications.

The whole-genome assembly of an endangered Salicaceae species: Chosenia arbutifolia (Pall.) A. Skv.

Background: As a fast-growing tree species, Chosenia arbutifolia has a unique but controversial taxonomic status in the family Salicaceae. Despite its importance as an industrial material, in ecological protection, and in landscaping, C. arbutifolia is seriously endangered in Northeast China because of artificial destruction and its low reproductive capability.

Complete chloroplast genome sequencing of five species and its application in the phylogeny and taxonomy of the genus.

In this study, whole chloroplast genomes of five species (, , , 'Hakuro Nishiki', and ) were sequenced. These chloroplast genomes were 155 ,605, 155, 763, 155, 552, 155, 538, and 155 ,550 bp in length, harboring 131 genes (77 unigenes), 37 tRNA genes, 8 rRNA genes, and 86 mRNA genes, respectively. The genes , , , , , , and were under positive selection among the 21 species.

Rodlike AgI/AgMoO Heterojunctions with Enhanced Visible-Light-Driven Photocatalytic Activity.

Novel AgI/AgMoO heterojunctions were prepared by reacting AgMoO microrods with an aqueous KI solution at room temperature. The composite materials, compared with neat AgI and AgMoO, showed much higher activities in the photocatalytic degradation of aqueous rhodamine B, methyl orange, tetracycline hydrochloride, and levofloxacin solutions under visible-light irradiation. The structures, morphologies, and other physicochemical properties of AgI, AgMoO, and AgI/AgMoO composites were studied via various characterization techniques.

Titanium dioxide and cadmium sulfide co-sensitized graphitic carbon nitride nanosheets composite photocatalysts with superior performance in phenol degradation under visible-light irradiation.

In this work, TiO-CdS-gCNNSs heterojunction photocatalysts were successfully synthesized. CdS was deposited on the surface of gCNNSs via electrostatic attraction; TiOC, TiOCO and TiON bonds were produced in TiO-CdS-gCNNSs, strengthening the interaction between TiO and gCNNSs. The TiO-CdS-gCNNSs photocatalyst showed excellent photocatalytic activity for phenol degradation under visible-light irradiation, which was higher than that of CdS-gCNNSs, CdS-TiO and TiO-gCNNSs.
