| 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Ni 0.39Mn0.61YO3.11±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MnO、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 H 2 ·mol HAc-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±δ catalyst, perovskite-like (Ni, Mn)YO3 phase was formed after calcination, and converted into thermostable Ni-Mn-Y-O species after reduction in H 2, along with the highly dispersed nickel nanoparticles. As a result, over the promoted Ni0.39Mn0.61YO3.11±δ catalyst, a stable catalytic performance with high HAc conversion (100%) and hydrogen yield (2.68 molH 2 ·mol HAc -1) was recorded, showing potential for hydrogen production. |
