Hydrothermal growth of well-aligned TiO2 nanorod arrays: Dependence of morphology upon hydrothermal reaction conditionsLI Yuxianga,ZHANG Meia,GUO Mina,and WANG Xidongb a Department of Physical... nanorod arrays (TNAs) were prepared on pretreated quartz substrates via hydrothermal method.The effect of the different preparation conditions on the growth morphologies of TNAs was systematically......
, Changsha 410083, China) Abstract: Silver-tin oxide powders were synthesized by the hydrothermal method with Ag(NH3)2+ solution and Na2SnO3 solution as raw materials and Na2SO3 as reductant... and the coprecipitation of silver and tin oxide is reached by the hydrothermal method. The silver-tin oxide composite powders have mainly flake shape of about 0.3 μm in thickness and there exists homogeneous......
of the particulate Zn5(CO3)2(OH)6 to ZnO whiskers. The presence of minor amount of EDTA in the hydrothermal solution promotes the one dimensional growth of ZnO whiskers, leading to the formation of ZnO whiskers... nanostructures[4-5]. The solution-based hydrothermal methods have also been used for the synthesis of 1D ZnO. Compared with the vapor phase methods, the hydrothermal method has some distinctive advantages......
