    Recovery of stoichiometry of Ta2O5 prepared by KrF excimer laser CVD from tantalum methoxide using microwave discharge of oxygen gas
    摘要:
    A flow of oxygen gas activated by passing through a microwave discharge plasma in a 100 and 200 W field was introduced into a deposition cham ber for tantalum oxide deposition by KrF laser photolysis of Ta(OCH3)(5), and the change of the non-stoichiometry of deposit was examined under the laser condition of 120 Hz and 200 Jm(-2). The stoichiometry of the deposit could be improved to a value of about 90% under the condition of rather low supply rate of Ta(OCH3)(5) (100 mg h(-1)). An effect of post-treatment laser following chemical vapour deposition (CVD) by KrF laser and/or microwave discharge of oxygen gas was also investigated, and it was found that activated oxygen species formed by KrF laser irradiation in an oxygen gas atmosphere which passed through a microwave discharge was effective in enhancing the oxidation of non-stoichiometric tantalum oxide prepared by KrF laser CVD.

  • Lewis Acid Strength of Interfacial Metal Sites Drives CH <sub>3</sub> OH Selectivity and Formation Rates on Cu‐Based CO <sub>2</sub> Hydrogenation Catalysts

    formation rates in CO2 hydrogenation on Cu‐based catalysts sensitively depend on the nature of the support and the presence of promoters. In this context, Cu nanoparticles supported on tailored supports (highly dispersed M on SiO2; M=Ti, Zr, Hf, Nb, Ta) were prepared via surface organometallic chemistry, and their catalytic performance was systematically investigated for CO2 hydrogenation to CH3OH. The
    铜基催化剂在CO 2加氢中CH 3 OH的生成速率敏感地取决于载体的性质和促进剂的存在。在这种情况下,通过表面有机金属化学方法制备了负载在定制载体上的Cu纳米颗粒(M在SiO 2上高度分散; M = Ti,Zr,Hf,Nb,Ta),并系统地研究了它们的催化性能,用于CO 2加氢成CH。3 OH。路易斯酸位点的存在增强了CH 3OH形成速率,可能是由于Cu纳米颗粒外围的甲酸和甲氧基表面中间体的稳定化所致,这是由路易斯酸强度的度量和表面中间体的检测所证明的。表面中间体的稳定取决于路易斯酸M位点的强度,该位点由吡啶吸附焓和与O配位的OCH 3的13 C化学位移来描述。这些化学位移在这里被证明是路易斯酸强度和CO 2氢化反应性的分子描述。
