•Novel polyimide-bound tris(2-thenoyltrifluoroacetonato)lanthanide(III) complexes (CMPI-Phen–Ln(TTA)3 (Ln=Eu, Sm)) were prepared.•CMPI-Phen–Ln(TTA)3 (Ln=Eu, Sm) exhibit excellent luminescent properties.•The 5% weight loss temperatures of CMPI-Phen and CMPI-Phen–Eu(TTA)3 are above 280 °C.Novel polyimide-bound tris(2-thenoyltrifluoroacetonato)lanthanide(III) complexes (CMPI-Phen–Ln(TTA)3) (Ln=Eu, Sm and TTA=2-thenoytrifluoroacetonato) were successfully prepared through the coordination reaction between 1,10-phenanthroline-functionalized polyimide (CMPI-Phen) and Ln(III)(TTA)3·2H2O (Ln=Eu, Sm). The products were characterized by Fourier transform infrared spectroscopy (FT-IR), 1H nuclear magnetic resonance (1H NMR), elemental analysis, inductively coupled plasma (ICP), thermo gravimetric analysis (TGA), and luminescence spectrometry. Fluorescence spectra revealed that CMPI-Phen–Ln(TTA)3 (Ln=Eu, Sm) in solid state exhibit an intense red and orange-red fluorescence of corresponding Eu(III) and Sm(III) under ultraviolet excitation, suggesting their potential application as luminescent materials. In addition, both CMPI-Phen and CMPI-Phen–Eu(TTA)3 have high thermal stability and their 5% weight loss temperatures are above 280 °C.

•Network-like polyimide/silica composite microspheres with a high SiO2 content.•Suspension polymerization method.•The 5% weight loss temperature of them was at about 503 °C.•A semi-interpenetrating network had formed.A typical of network-like polyimide/silica composite microspheres with a high SiO2 content was successfully prepared by a suspension polymerization method. The microstructure, morphology, surface composition and thermal property were characterized by infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and thermogravimetric analyzer (TGA), respectively. The results showed that the size of PI/SiO2 composite microspheres with 20–25 μm presented rough surface and an interpenetrating network had formed inside the spheres. The temperature of 5% weight loss was at about 503 °C, having higher thermal stability than pure PI.

•Successfully fabricated mesoporous TiO2 thin film on Al wire by sol-gel method with EISA.•Ni supported on this film and exhibits good methanation performance.•Investigate the decomposition temperature of template agent F127 in TiO2 precursor system.Mesoporous TiO2 film on Al wire was fabricated by sol-gel method with evaporation induced self assembly (EISA) process using F127 as templating agent in the mixed solution of ethanol and Tetra-n-butyl Titanate. The Ni/TiO2 film catalyst supported on Al wire was prepared by impregnation and the catalytic performance on methanation was carried out in a titanium alloy micro-reactor tube. It was shown that anatase mesoporous TiO2 film was prepared in this conditions (1 g F127,calcined at 400 °C and aged for 24 h), which has specific surface area of 127 m2 g−1 and narrow pore size distribution of 5.3 nm. Low calcined temperature (300 °C) cannot transfer film to anatase and decompose F127 completely. Ni/TiO2 film on Al wire catalyst was proved to be active in CO methanation reaction. And the CO conversion reaches 99% and CH4 selectivity close is to 80% when the reaction temperature is higher 360 °C.

•Amino ILs modified magnetic core/shell nanocomposite was synthesized.•The adsorbent possesses mesoporous structure and multiple active adsorption sites.•The adsorbent exhibited high adsorption capacity and rapid adsorption rate.•The adsorbent can be easily separated from solution by a magnet.Amino ionic liquids modified superparamagnetic mesoporous core/shell nanocomposite (Fe3O4@nSiO2@mSiO2@DHIM-NH2) was synthesized to remove orange II and amaranth from water. Due to the multiple active sites of the introduced ionic liquids, the adsorbent presents superior adsorption performance and instantaneous adsorption capacity. The maximum adsorption capacities are reached at pH 2 due to the protonation of amino groups, which are 153.06 and 84.40 mg g−1 for orange II and amaranth, respectively. The good stability, rapid adsorption kinetics, large adsorption capacity, and high separation efficiency make Fe3O4@nSiO2@mSiO2@DHIM-NH2 an efficient adsorbent for removing anionic contaminant from water.The excellent adsorption performance for removing anionic dyes was achieved by amino ionic liquids-modified Fe3O4@nSiO2@mSiO2 mesoporous core/shell nanocomposite.Download full-size image
