Construction of High‐Nuclear Cu_xS_y Nanocrystalline Catalyst from High‐Nuclear Copper Cluster

Abstract

A multi‐nuclear copper sulfide CuxSy with micro‐snowflake structure derived from a known four‐core copper cluster C28H36Cl6Cu4N4O5 was fabricated by hydrothermal method in mild condition. The growing process of the snowflake structure experienced from particles, to sheets and flowers, which depended on the reaction time. The prepared materials of high‐nuclear copper sulfide in different shapes were taken as catalysts for methylene blue and rhodamine B degradation. The degradation degree of the methylene blue reached up to 97.7% after 13 minutes and it needed 16 minutes for that of the rhodamine B up to 98.2%, which demonstrated that the snowflakes‐like CuxSy exhibited excellent photo‐catalytic property. Moreover, the high stability of the catalysts was confirmed by cycle experiments and SEM images.

Heterostructural NiCo2O4 Nanocomposites for Nonenzymatic Electrochemical Glucose Sensing

“…So far, various nanomaterials have been widely explored. Nano metals such as Ag, Au, Pt, Ni and Co [22][23][24][25][26], metal oxide such as CuO, ZnO [27][28], conducting polymers such as polypyrrole (PPy), polyaniline (PANI) [29][30] and conducting carbo-naceous materials like rGO, C-dots [31][32] have been used as non-enzymatic glucose sensors. However, the application of nanomaterials in non-enzymatic glucose sensors is limited by some factors.…”

Characterization of the Poplar R2R3-MYB Gene Family and Over-Expression of PsnMYB108 Confers Salt Tolerance in Transgenic Tobacco

“…The identification of R2R3-MYB gene family in poplar was performed according to a previous study (Chen et al, 2019). We downloaded the amino acid sequence of poplar protein from the Phytozome database (Tuskan et al, 2006;Goodstein et al, 2012).…”

Donor–Acceptor Copolymers with Rationally Regulated Side Chain Orientation for Polymer Solar Cells Processed by Non-Halogenated Solvent

“…39 – 46 Additionally, processing the PSCs with non-halogenated/green solvents is another essential prerequisite for their commercial applications. 47 – 52 Therefore, it is of vital significance to construct cost-effective, high-performance and green solvent processable polymer donors with low-cost starting compounds and shorted synthesis steps.…”
