Description
Technical Field
The invention belongs to the field of preparation and technology of photocatalytic materials, and particularly relates to transition metal doped defect-rich molybdenum disulfide, a preparation method thereof and application thereof in photocatalytic nitrogen fixation.
Background
Nitrogen (N) in the atmosphere2) Fixation to ammonia (NH)3) Is one of the most fundamental natural processes for the survival of all living beings and humans. The source of ammonia depends mainly on biological nitrogen fixation and industrial synthesis of ammonia. Wherein the industrial synthetic ammonia (Haber-Bosch method) lays the foundation of modern agriculture and greatly promotes the progress of modern civilization. However, this method requires high temperature (400 ≡ 600 ℃), high pressure (20-50MPa) to achieve dissociation of N ≡ N. And the reaction process needs to consume H2At the expense, this consumes 1-2% of the global energy costs. Therefore, in view of the concept of sustainable development, it is necessary to develop an eco-friendly synthesis method with low energy dependence to replace the Haber-Bosch method for ammonia synthesis. It is widely believed that the photochemical synthesis of ammonia by using solar energy as power has great potential. However, extensive studies have shown that photocatalytic NRR processes suffer from low photocatalytic quantum efficiency due to nonpolar N ≡ N bonds and higher bond energies (≈ 945 kJ/mol).
