The bimetal-bearing (CePt or LaPt) 12.tungstophosphoric acid (H3PW12.40 (PW)) catalysts supported on dealuminated USY zeolite (DUSY) were prepared by impregnation and characterized by XRD, BET, IR, and H2.chemisorption. Their catalytic activities were tested in the hydroisomerization of n-heptane with a continuous atmospheric fixed-bed reactor. After the steam treatment combined with the acid leaching, as well as the supporting with PW and the bimetals, the DUSY support retains the Y zeolite porosity and the PW well keeps its Keggin structure in catalysts. The doping of Ce into the catalysts enhances the dispersion of Pt on the catalyst surface. The Pt-bearing PW catalysts doped with Ce or La, especially Ce, exhibit much higher catalytic activity and selectivity than the catalysts without dopants at lowered reaction temperatures. At the optimal reaction conditions, i.e., the reaction temperature of 2.0℃ and WHSV of 1.4 h1, the catalyst with a Pt loading of 0.4%, PW loading of 10% and a molar ratio of Ce to Pt of 15:1 shows a conversion of n-heptane of 70.3% with a high selectivity for isomerization products of 94.1%.

In order to solve the serious leaching problem of supported heteropoly acid catalysts in polar reaction media, 12.molybdophosphoric acid encapsulated in the supercage of Cs^＋-exchanged Y zeolite was prepared by the ＂ship in the bottle＂ synthesis. The influence of ion-exchange conditions and the synthesis parameters on the encaosulation of PMo12.were investigated. The obtained solid sample was characterized by X-ray diffraction （XRD）, 31p magic angle spin nuclear magnetic resonance （MAS NMR） and Fourier Transform Infrared Spectroscopy （FT-IR）, and its catalytic activity in the esterification of acetic acid and n-butanol was tested. The ion-exchange time, concentration of aqueous Cs^＋ solution, pH value, and amount of Mo added in the synthesis mixture were revealed to influence the encapsulation very remarkably. Under the optimal conditions, 12.molybdophosphoric acid could be successfully encapsulated in the supercage of CsY zeolite, and the samples showed considerable catalytic activity and excellent reusability in the esterification reaction.

锂电池体系中负极表面固态电解质界面相(SEI)对锂电池性能起到至关重要的作用。然而,SEI结构和化学组成复杂,其形成机理至今仍未完全阐明,阻碍了锂电池的发展和应用。本文从方法学角度出发,采用表面增强拉曼光谱(SERS)“借力”策略,通过优化银纳米粒子的结构并借助其外来表面局域等离激元共振作用,开展以EC-DMC为溶剂的碳酸酯类电解液体系中SEI成膜过程的原位研究。为了确保可靠的原位SERS测试,我们设计了一种三电极体系气密拉曼电池。我们利用原位SERS方法,在纳米银电极上获得了SEI成膜过程的组成和结构信息。研究表明,SEI随电位变化呈现出双层结构,其中内层由薄且致密的无机组分构成,外层由疏松的有机组分构成。同时,研究发现LEMC是EC还原的主要成分,而不是LEDC,且金属锂参与的化学反应在形成稳定SEI中的起到关键作用。此外,锂发生沉积后,由于锂与银的合金效应导致其介电常数发生变化,从而削无法进一步增强SEI的拉曼信号。本文为深入理解负极表面SEI的形成及演变过程提供依据,并为今后开展锂电池体系相关界面过程的原位研究提供借鉴。
