Effects of reduction temperature and content of Pd loading on the performance Pd/CeO2 catalyst for CO oxidation

引用

Chinese Chemical Letters 2019年第6期30卷 1153-1156页

作者： Yue Yan Huaxi Li Zhanghui Lu xuewen wang Rongbin Zhang Gang Feng Key Laboratory of Jiangxi Province for Environment and Energy Catalysis College of Chemistry Nanchang University Nanchang 330031 China College of Chemistry and Chemical Engineering Jiangxi Normal University Nanchang 330022 China

The content of noble metal loading and the reduction process of the catalysts are important factors influence the economic indicator and catalytic performance for industrial catalysis. In the present work, Pd/CeO2NT (Pd supported on the CeO2 nanotubes) catalysts are prepared with the hydrothermal synthesized CeO2NT and glutathione (GSH) reduced Pd nanoparticles via impregnation. The content of Pd loading as well as the catalysts reduction temperature are optimized to the CO oxidation reduction. Our results show that the best Pd loading is 1.5%Pd/CeO2NT. The catalysts reduced at 350 ℃ for 2 h prior to catalytic reaction perform the best toward CO oxidation, which reaches completely CO conversion at 70 ℃. The XRD, Raman, H2-TPR, TEM, BET and XPS characterization reveal that the excellent catalytic performance of 350 °C 1.5%Pd/CeO2NT sample can be attributed the high Pd^0 species and oxygen vacancy in the sample, which are important factors influence the activity of the catalysts.

在求解作业车间调度问题(job-shop scheduling problem, JSP)的局部搜索算法中,构造移动执行后的邻域解严重影响了局部搜索算法的计算效率.为此,基于拓扑排序和工序最大弧数的相关理论,提出了调度解拓扑排序的划分方法,实现了邻域解拓扑排序的构造;并在邻域解的拓扑排序中,准确地识别了邻域解中头和尾时间发生改变的工序集合,从而实现了邻域解的快速、动态构造.实验结果表明:相比于目前的邻域解构造方法,所提出的邻域解的动态构造方法,在计算速度上有着明显优势,且能够显著地节省计算时间.
