1978年,我们曾报道了在光合作用催化电子理论指导下,用二氧化钛和特殊制备的铁粉的混合物为催化剂,在常温、常压下,用水作氢源,空气作氮源,应用近紫外光固定分子氮还原为氨的结果、由于照在地球表面的太阳光差不多一半是可见光,同时紫外光的每个光子的能量均比每个可见光光子的能量大,因 In 1978, we reported that under the guidance of the theory of photosynthesis catalytic electrons, with a mixture of titanium dioxide and specially prepared iron powder as a catalyst, under normal temperature and pressure, using water as a hydrogen source, air as a nitrogen source, the application of near ultraviolet light As a result of the reduction of the fixed molecular nitrogen to ammonia, since almost half of the sunlight striking the Earth’s surface is visible light and the energy of each photon of ultraviolet light is greater than that of each visible photon,
