提出拓扑化学行为概念,把对化合物性质最具影响力的因素归纳为拓扑生长力和拓扑阻滞力。根据该原理,利用价电子轨道能量对价电子距离矩阵进行修正。研究表明OET(轨道能量拓扑指数)对镧系元素和锕系元素的物理化学性质具有良好的应用，尤其是对尚未借助QSPR(定量结构性质关系)手段进行研究的光谱性质。LOO CV(留一法交叉检验)的结果验证了模型的良好稳定性和预测能力,采用的检验参数有：PRESS/SSY，S...

Cu-MCM-41介孔分子筛中不同价态铜上的吸附性能研究（Adsorption Behavior of Copper with Different Valences States in Cu-MCM-41）
Cu-MCM-41 介孔材料 CO吸附 C2H4吸附 吸附量热 红外光谱

合成了不同铜含量的Cu-MCM-41，高温还原后仍具有良好的介孔结构。孔壁中的铜容易被H2还原为Cu(0)。通过在氦气流中加热，可以导致孔壁中的Cu(II)还原为Cu(I)。MCM-41中不同价态的铜具有不同的吸附性能：Cu(0)强烈吸附O2，吸附热高达427 kJ·mol-1；Cu(I)在室温下几乎不吸附O2，表明Cu(I)在室温下较稳定；而Cu(I)在对CO与C2H4的吸附中，除了CO的吸附热...
