“…However, the extreme chemical inertness, high ionization energy and low electron affinity energy of N 2 molecules make the photocatalytic ammonia synthesis process extremely challenging. 23,101,102 Among all the photocatalysts used for ammonia synthesis, the highly efficient and stable BBS have made great breakthroughs, but the pure-phase BBS all suffer from severe photogenerated carrier complexation and low quantum efficiency. 23,101 Therefore, the development of highly efficient BBS for ammonia synthesis has become a research direction in recent years (Table 2).…”

Using semiconductor photocatalysts instead of the traditional Haber−Bosch procedure to produce ammonia is a promising strategy to save energy and prevent environmental pollution. Therefore, finding a suitable photocatalyst with high efficiency and stability has become one of the big challenges of research communities in the field of heterogeneous photocatalysis. Herein, S-scheme TiO 2 quantum dots (QDs)/Fe 3 S 4 heterojunction photocatalysts were synthesized through a hydrothermal route. The nitrogen photofixation measurements exhibited that the TiO 2 QDs/Fe 3 S 4 photocatalysts have excellent activities, where the generation of NH 3 by the optimized nanocomposite reached 16,624 μmol L −1 g −1 upon simulated sunlight. This amount was almost 19.9, 6.30, and 2.85 times as high as those of TiO 2 , TiO 2 QDs, and Fe 3 S 4 photocatalysts, respectively. The promoted photocatalytic ability was devoted to outstanding visiblelight absorption, accelerated segregation of photoinduced electron−hole pairs, and enhanced surface area. The key purpose of this research was the rational design of a photocatalyst based on TiO 2 QDs through a one-pot and facile fabrication procedure, which exhibits admirable performance in the field of photocatalytic nitrogen fixation. Considering the advantages of binary TiO 2 QDs/ Fe 3 S 4 photocatalysts, it is anticipated that this photocatalyst could be utilized in solar energy conversion processes.

“…The layered crystal structure bismuth bromide oxide (BiOBr) with suitable energy band position gives it excellent photocatalytic oxidation/reduction activity. [5,6] The atoms in the layers are joined by strong covalent bonds, and there exists a weak van der Waals force interaction among the layers. The open layered crystal structure provides enough space for atomic polarization.…”

The industrial ammonia synthesis process consumes a lot of energy and causes serious environmental pollution. As a sustainable approach for ammonia synthesis, photocatalytic nitrogen reduction employing water as the reducing agent has a lot of potential. A simple surfactant‐assisted solvothermal method is used to synthesize g‐C3N4 nanotubes with flower‐like spherical BiOBr grown inside and outside (BiOBr/g‐C3N4, BC). The hollow tubular structure realizes the full use of visible light by the multi‐scattering effect of light. Large surface areas and more active sites for N2 adsorption and activation are present in the distinctive spatially dispersed hierarchical structures. Particularly, the quick separation and transfer of electrons and holes are facilitated by the sandwich tubular heterojunctions and tight contact interface of BiOBr and g‐C3N4. The maximal NH3 generation rate of the BiOBr/g‐C3N4 composite catalysts can reach 255.04 μmol⋅ g−1⋅ h−1, and it is 13.9 and 5.8 times that of pure BiOBr and g‐C3N4. This work provides a novel method for designing and constructing unique heterojunctions for efficient photocatalytic nitrogen fixation.
