. The plateaus of LaNi 4.7 Al 0.3 and MlNi 4.5 Al 0.5 alloys were both lifted and inclined, the width of p c t curve was shorted, the absorbed hydrogen content was reduced drastically after poisoning.... The reasons of poison was analyzed through XPS and XRD. Keyword: carbon monoxide; hydrogen storage alloys; poisoning; Received: 1999-07-01 近年来......
Preparation and research on poisoning resistant Zr-Co based hydrogen storage alloysLI Hualing, WANG Shumao, JIANG Lijun, ZHANG Lidong, LIU Xiaopeng, and LI Zhinian Research Institute of Energy... by hydrogen mixed with CO, CO2, etc, which decreases the hydrogen storage property sharply. Zr-Co based hydrogen storage alloys with good poisoning resistance were prepared by alloying, fluorinating......
Sulfur poisoning and regeneration of MnOx-CeO2-Al2O3 catalyst for soot oxidation李亨烈,刘爽,翁端Laboratory of Advanced Materials, Department of Materials Science and Engineering, Tsinghua University摘 要:MnOx-CeO2-Al2O3 mixed oxides were prepared by impregnating manganese and cerium precursors on alumina powders via a sol- gel deposition method. The oxide......
