采用原位XRD、激光Raman光谱和TPR(程序升温还原)技术研究了CuO(w,%)/CeO2-Al2O3催化剂中CuO物种的存在形式及其CuO物种的迁移. 低温焙烧(300 ℃)催化剂, CuO以高分散和晶相两种形式存在于CeO2-Al2O3载体表层. 随着焙烧温度的升高, CuO开始从表层向CeO2内层迁移. 处于内层的CuO部分以晶相形式存在, 部分与Al2O3载体反应生成CuAl2O4. ...
运用电化学阻抗谱(EIS)、Raman光谱和XRD研究了石墨负极在1 mol/L LiPF6-EC∶DEC∶DMC电解液中的电化学循环扫描过程. EIS研究结果表明, 在电化学循环扫描4~10周范围内, SEI膜(固体电解质相界面膜)电阻随循环扫描周数增加近似线性增长, 但石墨负极/电解液界面总阻抗由于电荷传递电阻的降低而减小. Raman光谱研究结果表明, 在经历电化学循环扫描后, 活性材料表层...
以氯化醇钛盐表面反应法制备系列TiO2/SiO2,根据XRD，Raman和DRS表征分析，载体表面具有分子级分散的锐钛矿型TiO2微晶粒子和非晶TiOx物种。与本体TiO2相比，TiO2/SiO2的吸收带边显著蓝移，能隙增大为3.96 eV。当金属M(M：Pd, Cu和Ni)负载于TiO2/SiO2表面，可使其光吸收域扩展到可见光区，并引起吸收带边红移。相对Pd的负载，Cu, Ni的负载对TiO2...
采用原位XRD和激光Raman光谱等技术对CuO/Al2O3系列催化剂高温下的表面组成和体相结构的变化进行研究.结果表明,随着焙烧温度升高,CuO首先与载体Al2O3发生固相反应生成CuAl2O4.CuAl2O4层能阻止外层CuO进一步向载体Al2O3扩散,从而使部分CuO稳定在CuO/Al2O3催化剂的表层.
