简介：空CuO-CeO2-ZrO2nano粒子被作为反溶剂把甲醇用作溶剂和supercritical二氧化碳与supercritical反溶剂仪器准备。二个关键因素(即，压力和温度)被调查探索催化剂结构和药品化学药品性质的效果(即，形态学，减少的性质，氧存储能力和特定的表面区域)。产生材料与X光检查衍射(XRD)被描绘，高决定传播电子显微镜学(HRTEM)，Brunauer-Emmett-Teller(赌注)，氢温度规划了减小(H2-TPR)和氧存储能力(振荡)测量分别地。试验性的结果证明更低的温度支持了空结构nano微粒的生产。粒子形态学也显著地变化了，即稳固的构造然后首先被转移到空结构回到稳固的建设。为获得空nano粒子的最佳的条件在45点被决定
