前文报导了用二氧化钛和氧化了的铁粉的混合物作催化剂,在常温、常压下、用水作氢源,空气作氮源,利用近紫外光作能源,模拟兰绿藻等的光合固氮,把分子氮固定下来,并还原为氨。本文报导的是一种能利用可见光的、含有钼等杂质的硫化镉和前文相似的铁粉混合作催化剂,在常温、常压下,通过~(15)N 的同位数实验,以及绿光和红光的实验,证明它的确在可见光下可以用水作氢源,空气作氮源,固定分子氮并还原为氨。如果稍加聚光,在太阳光下,每克催化剂每小时的产率在100微克分子以上。文中也初步探讨了形成机理。
Previously reported using a mixture of titanium dioxide and oxidized iron powder as a catalyst at room temperature and atmospheric pressure, using water as a hydrogen source, air as a nitrogen source, the use of near ultraviolet light as an energy source to mimic green algae photosynthetic nitrogen fixation, Molecular nitrogen is fixed and reduced to ammonia. This article reports a visible light, containing molybdenum and other impurities of cadmium sulfide and similar iron powder mixture as a catalyst, at room temperature, atmospheric pressure, by ~ (15) N isotope experiments, as well as green and The experiment of red light proves that it can indeed use water as a hydrogen source, air as a nitrogen source, and fix molecular nitrogen and reduce it to ammonia under visible light. If lightly concentrated, the yield per gram of catalyst per hour under sunlight is above 100 micromolar. The paper also initially discussed the formation mechanism.
