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...

Thiophene hydrodesulfurization on clean and sulfur covered MoP(001): Theoretical survey of the positive effect of sulfur deposition on the catalytic performance.
Molybdenum phosphide (MoP) has been extensively experimentally shown to possess high and surprisingly increasing hydrodesulfurization (HDS) activities during the HDS process. In order to understand the HDS mechanism, we investigate the HDS of thiophene on clean and single-sulfur-atom-modified MoP(001) using self-consistent periodic density functional theory (DFT). Thiophene strongly prefers flat...

A planar dithiafulvene based sensitizer forming J-aggregates on TiO2 photoanode to enhance the performance of dye-sensitized solar cells.
A newly planar dithiafulvene sensitizer (DTF-C4) trending to form J-aggregates on the surface of mesoporous TiO2 by simply rinsing with a poor solvent acetonitrile was synthesized. We further show that the self-assembled J-aggregates optimized the TiO2surface utilization, enhanced the light harvesting ability by broadening and red-shifting the absorption, and suppressed the electron recombinatio...

[Compos. Sci. Technol.]Development of wave-transparent, light-weight composites combined with superior dielectric performance and desirable thermal stabilities
In this paper, a novel interfacial compatibilizer of soluble epoxy-terminated poly (p-phenylene-2, 6-benzobisoxazole) precursor (epoxy-prePBO) was synthesized to modify bisphenol A cyanate ester (BADCy) resin via copolymerization. Compared to PBO fibers/BADCy wave-transparent composites, the obtained PBO fibers/epoxy-prePBO modified BADCy (PBO fibers/PBO-co-BADCy) wave-transparent composite with...

(Macromolecules) Vanillin-derived High-performance Flame Retardant Epoxy Resins: Facile Synthesis and Properties
Lignin derivative vanillin when coupled with diamines and diethyl phosphite followed by reaction with echichlorohydrin yields high-performance flame retardant epoxy resins. Biorenewable and environment-friendly flame retardant alternatives to bisphenol A epoxy resins (having plenty of applications such as coatings, adhesives, composites, etc.) have captured great attention due to their ecologica...

High performance poly(N-aryleneindole ether) containing pyridine units as a novel acid response fluorescent detector
A novel high-performance polyindole containing a pyridine ring (P1)was successfully prepared by the catalyst-free nucleophilic substitution polycondensation of 4-hydroxyindole with 2,6-difluoropyridine via a C?N and C?O coupling reaction process. This semirigid polyindole P1 exhibits good thermal stability, and it can be dissolved well in common organic solvents. Fluorescent spectral studies ind...

Synthesis of High-Performance Polymers via Copper-Catalyzed Amination of Dibromoarenes with Primary Aromatic Ether Diamines
In this paper, we introduce three high-performance polymers with similar structures, poly(imino ether ketone) (PIEK)s, which are synthesized by the ligand free copper-catalyzed C-N cross coupling reaction of aryl halides and primary aromatic diamines at moderate temperature. The influence of the solvents, base, temperature, and catalyst ligands on the polycondensation reaction is investigated. T...
