| 摘 要： | 氮氧化物(NOx )严重威胁人体健康和生态环境。随着火电行业烟气NOx 初步实现超低排放，非电行业烟气NOx 排放控制成为重中之重。NH3 选择性催化还原NOx 是最有效的NOx 控制技术。非电行业烟气含有SO2 、碱性物质以及重金属等杂质，易导致催化剂中毒失活。针对NOx 净化催化剂低温活性不足、SO2 中毒、碱金属中毒以及复合中毒等关键难题，文章综述了各类低温抗中毒NOx 净化催化剂的研究进展，总结了提高催化剂的低温活性、抗SO2 中毒、抗碱金属中毒以及抗复合中毒的策略。文章为开发低温抗中毒NOx 净化催化剂提供了研究思路，为推进NOx 净化催化剂在非电行业烟气NOx 净化中的实际应用提供理论指导。

| Abstract: | Based on the two intrinsic properties, zero resistance and perfect diamagnetism, superconductors have great potential inthe application of energy, public transportation, and medical area. A large number of scientists devote to this field. Moreover, thestudy of the superconductivity and behind microscopic mechanism have also boosted the progress of the strongly correlated systemin condensed matter as well as the quantum mechanics. So far, ten scientists have been awarded the Nobel Prize on Physics due totheir contributions related to the study of superconductivity. In this paper, we will mainly discuss a minor quantum matter, the vortex,which is closely related to the macroscopic superconducting properties. This microscopic vortex matter can travel us around theunique properties of superconductivity and the frontier applications. |
