In a previous communication,we had reported the result of under the direction of the electron theory of catalysis of photosynthesis,with the compound of titanium dio- xide power and oxidizing iron powder as catalyst,water as hydrogen source,air as nitrog- en source and near ultraviolet light as energy source to reduce dinitrogen to ammonia under the common temperature and pressure.Bnt,so far as we know,on the surface of the earth,not only about half of the quantity of sunlight is visible light and the quantity of ultraviolet is small,but also the photonic energy of ultraviolet light is bigger than that of visible light.Therefore,any possibilty of finding some catalysts which can fulfil the dinitrogen fixation and reduce it to ammonia in the visible light would have great significan- ce both in theory and in practice.We prepared a series of catalysts.One of those is a ca- dmium sulfide containing 10% molybdenum compounding with iron powder as reported prev- iously. We proved that this catalyst can use the dinitrogenof air as nitrogen source with ~(15)N_2- enriched air.We also found this catalyst can use the visible light,until red light as ener- gy source when the green or red light is used iuthe monochromatic light experiment respe- ctively. When we used sunlight directly or used a lens to aggregate sunlight to irradiate sam- pies,the product yield of ammonia were about 26 and 110 μ mol/gram catalyst·hour res- pectively.
