2018年10月5日 · Well-defined aluminum phosphate hollow microspheres (AlPO4-HMs) of uniform size were synthesized via homogeneous precipitation using polystyrene (PS) as the template. The as-prepared AlPO4-HMs were characterized by FESEM, TEM, XRD, FTIR and N2 adsorption/desorption.

AlPO4 exhibits the highest reversible capacity (220.4 mA h g-1 after 50 cycles at 0.1C), best cycling performance (capacity retention of 74.4% after 50 cycles at 0.1C) and rate capability (175.3...

Microporous triclinic AlPO4-34, known as APO-Tric, serves as an excellent water adsorbent in thermal energy storage, especially for low temperature thermochemical energy storage.

用X射线衍射形貌法研究了AlPO4晶体中的微观缺陷。 在所研究的晶体中,主要晶体缺陷是生长层,沉淀物和位错。 位错密度在晶体表面附近最大,晶体中部较低。 位错主要起源于热应力和由沉淀物或生长层所造成的晶格畸变。 多数位错的柏氏矢量是b= (a+c)型,部分的是b=a [2110]。 分析了晶体缺陷与生长条件之间的关系。 控制生长过程中的温度波动,特别是晶体出炉时的冷却速度,对提高晶体完美性是重要的。 The microscopic defects in AlPO4 crystals have been studied by means of …

2020年10月1日 · AlGaPO 4 molecular sieve becomes more hydrophilic and has stronger acidity at both Brönsted and Lewis acid sites. Aluminophosphate molecular sieves are recognized as very promising materials for catalysis, adsorption, and separation. This study presented an attempt to synthesize LTA-type AlPO4 and AlGaPO4 molecular sieves by an ionothermal method.

2022年12月15日 · By combining several techniques such as in situ heating X-ray diffraction (XRD), scanning electron microscopy (SEM) and nuclear magnetic resonance (NMR), we explored the formation mechanism of AlPO 4 during the synthesis process of NASICON-type Li 1.5 Al 0.5 Ti 1.5 (PO 4) 3 (LATP) electrolyte and we showed the effects of the annealing ...

2015年12月11日 · Microporous zeolite-like aluminophosphate AlPO4-34 is a very promising material for water-adsorption-based thermal energy storage. To obtain better understanding of the dehydration of this material, a detailed variable-temperature nuclear magnetic resonance (NMR), X-ray diffraction (XRD), and first-principle The Creative World of Porous Materials

2003年1月21日 · Find more information on the Altmetric Attention Score and how the score is calculated. We have used several solid-state NMR techniques in conjunction with powder X-ray diffraction (XRD) and FT-Raman spectroscopy to characterize the structures of the intermediate phases of AlPO 4 -11 molecular sieve synthesis.

The surface of layered LiNi1/3Co1/3Mn1/3O2 was coated with AlPO4 by co-precipitation method and followed by heat treatment. The prepared samples were characterized by XRD and SEM. The samples...

2011年10月18日 · Powder X-ray diffraction (PXRD) patterns of as-synthesized products were recorded on a Bruker-D8 diffractometer with Ni-filtered CuKa radiation (step size of 0.02°, count times = 6°/min, 2θ range = 3–35°). The morphology of crystals was observed on a SHIMADZU SS-550 scanning electron microscope.
