Size-Tunable Hydrothermal Synthesis of SnS(2) Nanocrystals with High Performance in Visible Light-Driven Photocatalytic Reduction of Aqueous Cr(VI)
SnS2 nanocrystals with adjustable sizes were synthesized via a hydrothermal method from the aqueous solution of common and inexpensive SnCl4·5H2O, thioacetamide and citric acid, simply by varying the reaction temperature and reaction time. The structures, Brunauer–Emmett–Teller (BET) specific surface areas and optical properties of the resultant SnS2 nanocrystals were characteri...

Improvement of photocatalytic activity of high specific surface area graphitic carbon nitride by loading a co-catalyst
Graphitic carbon nitride (g-C3N4) was synthesized by heating melamine and was then treated with sodium hydroxide solution under a hydrothermal condition to obtain g-C3N4 with a large specific surface area (HSSA). HSSA shows higher photocatalytic activity for decomposition of acetaldehyde than that of original g-C3N4. HSSA was modified with RuO2 as a co-catalyst by the impregnation method...

A facile one-pot route for preparing cellulose nanocrystal/zinc oxide nanohybrids with high antibacterial and photocatalytic activity
Cellulose nanocrystal/zinc oxide (CNC/ZnO) nanohybrids were prepared through citric acid/hydrochloric acid hydrolysis of commercial microcrystalline cellulose (MCC), and simple precipitation with zinc nitrate aqueous solution [Zn(NO3)2·6H2O] via one-pot green synthesis, in which preparation and modification of CNCs were performed simultaneously and the obtained CNCs with carboxyl groups cou...

Use of electrospinning to directly fabricate three- dimensional nanofiber stacks of cellulose acetate under high relative humidity condition
Unique structure-controllable three-dimensional (3D) nanofiber stacks of cellulose acetate (CA) were fabricated successfully by simply increasing relative humidity (RH) during the electrospinning process. It is found that once the RH exceeding 60 %, 3D flocculent nanofiber stacks would grow on the flat plate collector toward the needle tip without using special assisting apparatus or preparing spe...

Facile extraction of thermally stable cellulose nanocrystals with a high yield of 93% through hydrochloric acid hydrolysis under hydrothermal conditions
A facile approach for extracting cellulose nanocrystals (CNCs) was presented through hydrochloric acid hydrolysis of cellulose raw materials under hydrothermal conditions. The influences of preparation parameters, such as reaction time, reaction temperature, and acid-to-cellulose raw material ratio, and different neutralization methods on the yield, microstructure and properties w...

[J Mater Chem A]Indacenodithiophene: A Promising Building Block for High Performance Polymer Solar Cells
Harvesting energy directly from sunlight using photovoltaic technology has become an essential component of future global energy production. Although silicon-based inorganic materials have still played a dominant role in the market, problems for inorganic materials-based solar cells mainly lie in (1) high cost of production and technical difficulties in the fabrication of large-ar...

The Hierarchical Structure of Water-Assisted Injection Molded High Density Polyethylene: Small Angle X-ray Scattering Study
Journal of Applied Polymer Science，2012，125（3）：2297~2303
High density polyethylene (HDPE) was molded by a new polymer processing method, that is, water-assisted injection molding (WAIM), and its hierarchical structure was studied by two-dimensional small angle X-ray scattering (SAXS). For comparison, the hierarchical structure of HDPE molded by conventional...

(ACS Sustain. Chem. Eng.) Hexahydro-s-triazine: A Trial for Acid-Degradable Epoxy Resins with High Performance
Hexahydro-s-triazine (HT) derivatives are acidsensitive compounds. 4,4′,4″-(1,3,5-Hexahydro-s-triazine-1,3,5-triyl) tris(N-(2-aminoethyl) benzamide) (HT-A) bearing three amino groups was synthesized as a curing agent to prepare the acid-degradable epoxy resin. The chemical structures of HT-A and its precursor were confirmed by 1H NMR and 13C NMR. The synthesized HT-A, as well as the commer...

32. High-performance conductive materials based on the selective location of carbon black in poly(ether ether ketone)/polyimide matrix
A novel high performance conductive material with excellent comprehensive properties was prepared by melt-blending, and its performances were adjusted by controlling the selective location of carbon black (CB) in poly(ether ether ketone) (PEEK)/thermoplastic polyimide (TPI) matrix. With increasing the CB loadings, the morphology of PEEK/TPI blends changed from sea-island to co-continuous structure...
