Stable and efficient SnO2 electrodes are very promising for effectively degrading refractory organic pollutants in wastewater treatment. In this regard, we firstly prepared Ti3+ self‐doped urchin‐like rutile TiO2 nanoclusters (TiO2‐xNCs) on a Ti mesh substrate by hydrothermal and electroreduction to serve as an interlayer for the deposition of Sb−SnO2. The TiO2‐xNCs/Sb−SnO2 anode exhibited a high oxygen evolution potential (2.63 V vs. SCE) and strong ⋅OH generation ability for the enhanced amount of absorbed oxygen species. Thus, the degradation results demonstrated its good rhodamine B (RhB), methylene blue (MB), alizarin yellow R (AYR), and methyl orange (MO) removal performance, with the rate constant increased 5.0, 1.9, 1.9, and 4.7 times, respectively, compared to the control Sb−SnO2 electrode. RhB and AYR degradation mechanisms are also proposed based on the results of high‐performance liquid chromatography coupled with mass spectrometry and quenching experiments. More importantly, this unique rutile interlayer prolonged the anode lifetime sixfold, given its good lattice match with SnO2 and the three‐dimensional concave–convex structure. Consequently, this work paves a new way for designing the crystal form and structure of the interlayers to obtain efficient and stable SnO2 electrodes for addressing dye wastewater problems.

A linear polystyrene-isopropenyl phosphonic acid (PS-IPPA) copolymer was newly synthesized by free radical reaction in solution with isopropenyl phosphonic acid (IPPA) and styrene. Zirconium poly(styrene-isopropenyl phosphonate)-phosphate acid (ZPS-IPPA) was also synthesized. The benzene rings of ZPS-IPPA were hydroxylated and then further reacted with Mn(salen)Cl. Thus the heterogeneous catalyst, Mn(salen) axially immobilized onto ZPS-IPPA was synthesized. These substances were characterized by IR spectra, X-ray diffraction (XRD), SEM, TEM, NMR, thermogravimetric analysis, and AAS. The catalyst showed good activity to epoxidation of styrene, which is close to that of the corresponding homogeneous catalyst. Copyright © 2008 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Stable and efficient SnO 2 electrodes are very promising for effectively degrading refractory organic pollutants in wastewater treatment. In this regard, we firstly prepared Ti 3+ self-doped urchin-like rutile TiO 2 nanoclusters (TiO 2-x NCs) on a Ti mesh substrate by hydrothermal and electroreduction to serve as an interlayer for the deposition of Sb-SnO 2 . The TiO 2-x NCs/Sb-SnO 2 anode exhibited a high oxygen evolution potential (2.63 V vs. SCE) and strong ⋅OH generation ability for the enhanced amount of absorbed oxygen species.

CuO@Al nanothermites with Al shell and CuO core were successfully fabricated via a simple self-assembly route. The composition and morphology of CuO@Al nanothermites were analyzed by x-ray diffraction and field-emission scanning electron microscopy in detail. When the equivalence ratio was 1.0, the heat output of CuO@Al nanothermites reached 1252 J g -1 , which was significantly larger than that of the Al/CuO prepared by ultrasonic mixing. The greatest heat output of CuO@Al nanothermites reached 1860 J g -1 , demonstrating outstanding exothermic properties, which ascribed to their unique core-shell structure. This study provides a new strategy about the design and advancement of highly exothermic nanothermites.
