| 摘 要： | 为了有效地从生物质衍生的乙酸中获得高氢气产率,通过水热法合成了一系列的NiMnY催化剂并用于乙酸自热重整(ATR)过程中,并采用X射线衍射(XRD)、N2吸附-脱附测试、H2程序升温还原(H2-TPR)探究催化剂中的内在联系。在Ni0.39Mn0.61YO3.11±δ催化剂中,经焙烧后形成了类钙钛矿型(Ni,Mn)YO3物相;经氢气还原后,转化为含有Mn O、Y2O3和高分散Ni纳米粒子的热稳定的Ni-Mn-Y-O物种。Ni0.39Mn0.61YO3.11±δ具有高效稳定的产氢催化性能,乙酸转化率高达100%,氢气产率达到2.68 mol_(H2)·molHAc-1。

| Abstract: | To effectively achieve high hydrogen yield from biomass-derived acetic acid(HAc),a series of NiMnY catalysts were prepared by hydrothermal method and tested in auto-thermal reforming(ATR)of HAc.X-ray diffraction(XRD),N2 adsorption-desorption test and H2-temperature-programmed reduction(H2-TPR)were carried out to explore the internal relationship within these NiMnY catalysts.Over the Ni0.39Mn0.61YO3.11±δcatalyst,perovskite-like(Ni,Mn)YO3 phase was formed after calcination,and converted into thermostable Ni-Mn-Y-O species after reduction in H2,along with the highly dispersed nickel nanoparticles.As a result,over the promotedNi0.39Mn0.61YO3.11±δcatalyst,a stable catalytic performance with high HAc conversion(100%)and hydrogen yield(2.68 mol_(H2)·molHAc-1)was recorded,showing potential for hydrogen production. |
