Ultrathin Nanowires—A Materials Chemistry Perspective

2009

The recent years have seen an explosive interest in one‐dimensional nanostructures1, as testified by the number of citations this field has accrued; as customary, its blossoming was enabled by chemical breakthroughs that allowed the reproducible and affordable synthesis of such structures.2, 3 The limitations of those syntheses was in the diameter of the nanowires that it could produce (hardly < 10 nm), and in the use of expensive and low‐yield techniques, such as chemical vapor deposition (CVD). This paper attempts to summarize the very recent chemical breakthroughs that have allowed the production of ultrathin nanowires, often in solution, and often in gram‐scale quantities. By no means is this a comprehensive coverage of the field, which can in part be found in other excellent reviews1, 2, 4–6 but a selection of those contributions that we feel would most help put this emerging field in perspective. We will review the various synthetic strategies, their pros and cons, and we will give our best guesses as to the future directions of the field and what we can expect from it.

“…In addition, both pure and rare earth-ion doped ceria find potential applications as oxygen ion conductors in solid oxide fuel cells, gate oxides in metal oxide semiconductor devices and ultraviolet (UV) blocking materials in UV shielding (Yu et al 2005;Miki et al 1990;Tsunekawa et al 2000). Nanostructured CeO 2 has been prepared by various methods (Sathyamurthy et al 2005;Yin et al 2002;Taniguchi et al 2008;Godinho et al 2007).…”

Structural studies and luminescence properties of CeO2:Eu3+ nanophosphors synthesized by oxalate precursor method

et al. 2014

A novel synthesis strategy to prepare CeO 2 :Eu 3? nanophosphors and its luminescence behavior is reported. Different structural characterization techniques such as X-ray diffraction, transmission electron microscope and thermogravimetric analysis reveal that thermal decomposition of oxalate precursor is an effective pathway to produce rare earth oxide nanocrystals. Optical characterizations of the CeO 2 :Eu 3? were done by UV-Visible absorption, photoluminescence excitation and emission spectra. The presence of structural defects and their role on the band gap and luminescence were discussed on the basis of absorption and emission studies.

“…Lykhach [13,14] also found that CeO 2 activation led to the rapid formation of carbonate and surface carboxylates. Meanwhile, various 1D and 2D CeO 2 nanostructures, [15][16][17] including nanorods, [18] nanowires, [19] nanotubes, [20,21] nanobelts [22,23] and other morphologies [24][25][26][27][28] had been synthesized via the thermal decomposition of CeCO 3 OH precursors, which was often prepared by solution precipitation, [29] sol-gel, [30] microemulsion, [31] sonochemical, [32] hydrothermal methods. [33] However, these synthetic processes usually were complicated with high synthesis cost due to the expensive templates and additives.…”

Three morphology controllable CeO 2 crystals were successfully synthesized via the thermal decomposition of CeCO 3 OH precursors, which was newly prepared on the basis of a simple and template-free hydrothermal reaction between CeCl 3 solution and a CO 2 -storage material (CO 2 SM). In the formation processes of three CeCO 3 OH precursors, the CO 2 SM could be newly used as raw material and structural director. Meanwhile, the results presented the wider pH values (5.24-8.35) for isoelectric point of CeCO 3 OH precursors. After the CeCO 3 OH precursors were isolated, the filtrate could be recycled to absorb CO 2 again and prepare CeCO 3 OH precursors with two special polymorphs. Three as-prepared CeO 2 crystals by annealing three CeCO 3 OH precursors at 500 8C for 4 h showed the maximum adsorption amounts of 23.5, 18.7 and 20.5 mg/g for 8% CO 2 /N 2 mixture. As a result, this work provided the wider pH values for isoelectric point of CeCO 3 OH precursors and a simple method for the preparation of CeO 2 crystals with a short time and CO 2 adsorption properties.
