Hydrothermal method on preparation nano-meter micro-porous Ni _xZn(_1-x)Fe₂O₄ crystals

Nanometer micro-porous Ni_xZn_(1-x) Fe ₂O₄ power was synthesized by hydrothermal method. This is first time to apply template to the synthesis. The structure, characteristics and crystal appearance are studied further by XRD, DSC, TEM, etc. It is found that nanometer micro-porous crystal is well-crystallized, well-degree of dispersion and smaller than 100nm in diameter. Moreover, tri-ethylamine can be used to be a ideal template in this synthesis, and the first time it is reported in our country. The synthesis mechanism is also preliminary discussed in this paper.
