The effect of preparation conditions on the performance of Ni-based catalysts was investigated for glycerol steam reforming. La 0.7 Ce 0.3 NiO 3 mixed oxides were synthesized using different solution concentrations and calcination temperatures by a co-precipitation method. Brunauer–Emmett–Teller, inductively coupled plasma, X-ray diffraction, temperature-programmed reduction, field emission scanning electron microscopy, CO 2 -temperature-programmed desorption, thermal gravity analysis, and Raman spectroscopy were performed to characterize the catalysts. With an La 2 NiO 4 phase at lowest solution concentration, a catalyst precursor included an LaNiO 3 phase instead of La 2 NiO 4 at other solution concentrations. At a low calcination temperature of 700 °C, it was found that the smaller particle size of CeO 2 incorporated more lanthanum and higher surface basicity, and the La 2 O 2 CO 3 phase could effectively inhibit and eliminate coking leading to the better performance of catalysts.

Silicon with high theoretical specific capacity is one of the most promising candidates for lithium-ion battery anode materials. However, due to its low electrical conductivity, large volume expansion and unstable...

Use NH4F as the electrolyte, prepared TiO2 nanotubes which orderly arranged by anodic oxidation. CdS was load to the TiO2-nanotubes by using chemical deposition method, then controlled size of CdS particles and uniformly load had been found when the EDTA-2NA was mixed in. The structure and morphology of TiO2 nanotubes and modified TiO2 nanotubes were observed by SEM. Use humic acid as simulate pollutant, investigate the efficiency of the CdS / TiO2nanotubes photocatalytic oxidation of organic compounds .The results show that CdS modified TiO2nanotubes arrays after added EDTA-2NA, the degradation rate of humic acid increased from 57.1 % to 85.4 % after illumination.

This article provides a low cost and green environmental preparation method to produce a high performance of stannum-carbon lithium battery anode material. The advantage of this method is not only for improving the performance and stability comparing with the stannum-carbon lithium battery, but also show a way for the industrial scale for the applications at the same time. This paper provides a reasonably designed hybrid composite as lithium ion battery anode that shows a reversible capacity of 440 mAh g À 1 after 500 cycles at 1.0 A g À 1 . This result is mainly attributed to the nanocrystallization of stannum and the introduction of expansion space by combination of wheat flour nature properties and redox process.
