美国加利福尼亚大学的G.N.Schrauger等人利用太阳光通过催化过程,将氮与水合成氨的工作首获成功。图1所示的这个反应过程,就是所谓利用太阳光从取之不尽的氮与水直接合成高能量的氨和肼。这可以说曾是化学家的理想。N_2(g)+3H_2O(1)hv→TiO_2金属氧化物2NH_3(g)+1.5O_2.△G~(298)=183kcal/mole(千卡/克分子) G.N.Schrauger, University of California, the United States, the use of sunlight through the catalytic process, nitrogen and water ammonia first successful work. The reaction process shown in Figure 1 is the direct use of sunlight to synthesize high-energy ammonia and hydrazine directly from inexhaustible nitrogen and water. This can be said to have been the ideal chemist. N 2 (g) + 3H 2 O (1) hv → TiO 2 metal oxide 2NH 3 (g) + 1.5O 2 · ΔG 298 = 183 kcal / mole
