A method for catalytic ammonia synthesis under concentrated solar energy and related catalysts. The method includes placing a catalyst in a reaction apparatus, feeding nitrogen and hydrogen into the reaction apparatus, and controlling a surface temperature of the catalyst to reach about 300&#xb0; C. to 550&#xb0; C. under irradiation of concentrated sunshine, to synthesize ammonia. The catalyst includes an amorphous and electron-rich black nano TiO(0&#x3c;z&#x3c;2) with a disordered surface serves as a carrier material, and an elemental nano-crystal of Fe or Ru serves as an active ingredient. The active ingredient is loaded on the carrier material. Sunshine is used as the energy during ammonia synthesis reaction, and light in the whole wave band can be utilized sufficiently. Ammonia can be synthesized under solar energy with a high efficiency, and no fossil energy or electrical energy is needed. A synergetic catalytic effect of optical energy and thermal energy can be obtained.
