| 1 | Modes of occurrence of arsenic in high-arsenic coal by extended X-ray absorption fine structure spectroscopy显示文摘The concentration ranges of As and Sb in six Late Permian high-arsenic coals collected from Xingren and Xingyi, Guizhou Province are 94.1 μg·g -1-3 2 and 8 1 μg·g -1-120 μg·g -1, respectively. Based on the mineralogical analysis, no arsenic and arsenic-bearing minerals are detected in these samples and arsenic occurs in coal macerals. By extended X-ray absorption fine structure(EXAFS) spectroscopy, we have found that arsenic in these high-arsenic coal samples coordinates with oxygen; the coordination number of As with oxygen for these samples is 4 except one sample(H-9) for which the coordination number of As is 3. Therefore, arsenic in these high-arsenic coals does not occur in sulfide minerals, but occurs in arsenate or arsenite phase, and the preponderance of As is in arsenate of As 5+. | Fenghua Zhao Deyi Ren Baoshan Zheng Tiandou Hu Tao Liu | 1998 | Chinese Science Bulletin1998，43，19： | 7 |

| 14 | Annealing crystallization and catalytic activity of ultrafine NiB amorphous alloy显示文摘Annealing crystallization of ultrafine NiB amorphous alloy prepared by the chemical reduction method was studied by DTA, XRD and XAFS techniques. The XRD and XAFS results have revealed that the crystallization process of ultrafine NiB amorphous alloy proceeds in two steps. First, ultrafine NiB amorphous alloy is crystallized to form metastable nanocrystalline Ni3B at an annealing temperature of 325℃. Second, the nanocrystalline Ni3B is further decomposed into crystalline Ni at 380CCC or higher tempera ture, the local structure around Ni atoms in resultant product is similar to that in Ni foil. It was found that the catalytic activity of nanocrystalline Ni3B for benzene hydro-genation is much higher than that of ultrafine NiB amorphous alloy or crystalline Ni. The result indicates that the active sites of nanocrystalline Ni3B for benzene hydrogena-tion are composed of both Ni and B with proper geometry configuration. | WEI Shiqiang LI Zhongrui ZHANG Xinyi CHEN Changrong LIU Wenhan WANG Xiaoguang HU Tiandou XIE Yaning LIU Tao | 2001 | Chinese Science Bulletin2001，46，6： | 0 |
