【Applied Catalysis B】Fabrication of hollow mesoporous SiO 2-BiOCl@ PANI@ Pd photocatalysts to improve the photocatalytic performance under visible light
A facile method was developed to synthesize a series of hollow mesoporous SiO2-BiOCl@PANI@Pd (HBPP) photocatalysts with super adsorption performance, plasmonic effect and fast interfacial charge migration. The samples were characterized by XRD, FETEM, FT-IR, XPS, DRS, etc. Photocatalytic degradation of methyl orange (MO) by HBPP composites was investigated.
Results showed that the photoca...

【Chemical Engineering Journal】Preparation of lipase/Zn3(PO4)2 hybrid nanoflower and its catalytic performance as an immobilized enzyme
A facile and rapid method is reported in this paper to prepare a novel immobilized enzyme named lipase/Zn3(PO4)2 hybrid nanoflower. The growth mechanism of the nanoflower has been studied in detail and can be described as the following four steps: crystallization and coordination, in-situ precipitation, self-assembly, size growth. Addition amount of lipase, reaction temperature and stirring...

【J. Phys. Chem. C】Tunable Permittivity in High–Performance Hyperbranched Polyimide Films by Adjusting Backbone Rigidity
Currently, low-dielectric polyimides (PIs) such as fluorinated or porous PIs exhibit a low-dielectric property but have undesirable mechanical and/or thermal properties. Therefore, it is crucial to find a more considerate method that could lower the permittivity, while maintaining or improving the mechanical and thermal properties. Herein, a series of hyperbranched (HB) PI films were synthes...

High-Performance Visible-Light-Driven SnS(2)/SnO(2) Nanocomposite Photocatalyst Prepared via In situ Hydrothermal Oxidation of SnS(2) Nanoparticles
SnS2/SnO2 nanocomposites with tunable SnO2 contents were prepared via in situ hydrothermal oxidation of SnS2 nanoparticles in 0.375–4.5 mass% H2O2 aqueous solutions at 180 °C for 0–12 h. The structure, composition and optical properties of the as-prepared SnS2/SnO2nanocomposites were characterized by X-ray diffraction, transmission electron microscopy, high-resolution transm...

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...

[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...

Synthesis and photocatalytic performance of yttrium-doped CeO2 with a porous broom-like hierarchical structure
In this study, yttrium-doped CeO2 with a broom-like porous hierarchical structure was successfully prepared by a simple template-free hydrothermal method with cerium nitrate hexahydrate and yttrium nitrate hexahydrate as original materials. Through systematic experiments, the different effects of doping concentrations on characteristics of the ceria were examined in detail and the optimal doping r...

(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...

41. Microporous polyimide networks constructed through a two-step polymerization approach, and their carbon dioxide adsorption performance
Based on a dianhydride monomer 2,5- bis(3,4- dicarboxyphenoxy)-4''''''''''''''''-phenylethynyl biphenyl (PEPHQDA) containing a crosslinkable phenylethynyl pendant group, microporous polyimide networks (HBPI-CRs) were prepared through a two- step pathway combining polymerization and crosslinking reactions. Specifically microporous features such as surface morphology, microporous structure and unifo...
