“…Consequently, much effort have been devoted to reducing the recombination of photogenerated electron‐hole pairs by extending the light absorption from UV to visible light region . Nowadays, Bi 2 MoO 6 , as a typical aurivillius oxide, has drawn much attention for many photocatalytic reactions because of its ion‐conductive, dielectric, luminescent suitable band gap and photocatalytic properties . However, as far as we know, it has not been used for the investigation of photocatalytic decomposition of N 2 O yet.…”

A series of nanobelt‐like Bi2MoO6 photocatalysts were design and controllably constructed via a simple hydrothermal approach, and their catalytic performances were investigated for photocatalytic decomposition of N2O for the first time. It was found that Bi2MoO6 synthesized at 170 °C (BM‐170) exhibits the highest photocatalytic activity with 21.7% N2O conversion at 25 °C under UVA irradiation (λ=365 nm) for 12 h, and that the excellent activity should be attributed to its highest content of Oads, strongest absorption capacity for visible light, lowest recombination rate of photo‐generated electron‐hole pairs, and highest separation efficiency for photogenerated charge carriers. Therefore, this study shed new light on the understanding and application of Bi2MoO6 catalysts for photocatalytic decomposition of N2O.

“…Due to the charge compensation, two redox couples (Ce 3+ /Ce 4+ and Mo 4+ /Mo 6+ ) and oxygen vacancies generated, which facilitated a better electron excitation and the one‐electron and two‐electron reactions ( Figure a,b). Apart from doping, OVs can also be introduced via reduction method, postsynthesis etching treatment and hydrothermal/solvothermal synthesis with additions …”

“…Analyzed by DFT calculations, the width of the CB bottom of Bi 2 MoO 6 is relatively narrow, meaning a large reciprocal effective mass of photoinduced electrons, which implies a sluggish mobility . In addition, considering the contradiction between wide light‐utilization range and strong redox ability, pure Bi 2 MoO 6 is incompetent to produce the highly oxidizing superoxide radicals under irradiation, interfering with a satisfactory organic pollutant degradation …”

“…Recently, Wang et al designed a novel C‐doped Bi 2 MoO 6 , significantly shortening the distance in transportation of carriers and remarkably enhancing the redox ability without sacrificing any absorption of light . Guo et al constructed a Bi 2 MoO 6− x @Bi 2 MoO 6 core–shell structure, which not only promoted the solar light utilization and suppressed the charge recombination but also improved the surface reactivity, achieving excellent pollutant degradation performance . Meanwhile, various Bi 2 MoO 6 ‐based heterojunctions, such as Bi 2 MoO 6 /AgX (X = Cl, Br, I), Bi 2 MoO 6 /Ag 3 XO 4 (X = P, V), Bi 2 MoO 6 /CdS and Bi 2 MoO 6 /MOFs, etc.…”

Highly active photocatalysts driving chemical reactions are of paramount importance toward renewable energy substitutes and environmental protection. As a fascinating Aurivillius phase material, Bi 2 MoO 6 has been the hotspot in photocatalytic applications due to its visible light absorption, nontoxicity, low cost, and high chemical durability. However, pure Bi 2 MoO 6 suffers from low efficiency in separating photogenerated carriers, small surface area, and poor quantum yield, resulting in low photocatalytic activity. Various strategies, such as morphology control, doping/defect-introduction, metal deposition, semiconductor combination, and surface modification with conjugative π structures, have been systematically explored to improve the photocatalytic activity of Bi 2 MoO 6 . To accelerate further developments of Bi 2 MoO 6 in the field of photocatalysis, this comprehensive Review endeavors to summarize recent research progress for the construction of highly efficient Bi 2 MoO 6 -based photocatalysts. Furthermore, benefiting from the enhanced photo catalytic activity of Bi 2 MoO 6 -based materials, various photocatalytic applications including water splitting, pollutant removal, and disinfection of bacteria, were introduced and critically reviewed. Finally, the current challenges and prospects of Bi 2 MoO 6 are pointed out. This comprehensive Review is expected to consolidate the existing fundamental theories of photo catalysis and pave a novel avenue to rationally design highly efficient Bi 2 MoO 6 -based photocatalysts for environmental pollution control and green energy development.

Fe (III)-grafted Bi 2 MoO 6 nanoplates (Fe (III)/BMO) with varying small quantity of Fe (III) clusters modification were fabricated through a simple hydrothermal and impregnation process. The characterization results indicate that the modification of Fe (III) clusters on the surface of Bi 2 MoO 6 nanoplates with intimate interfacial contact is beneficial to the expansion of visible light absorption range and the separation of photoinduced carriers during the interface charge transfer process. The photocatalytic properties of the samples were studied by degradation of tetracycline (TC) and selective aerobic oxidation of biomass-derived chemical 5-hydroxymethylfuraldehyde (HMF) under visible light. The 1.5 wt% Fe (III) clusters-grafted Bi 2 MoO 6 nanoplates exhibited optimum photocatalytic activity, which is the TC degradation kinetic rate constant is 5.3 times higher than that of bare BMO, and the highest HMF conversion of 32.62% can be obtained with a selectivity of 95.30%. Furthermore, a possible visible light photocatalysis mechanism over Fe (III)/BMO sample has been proposed. This study may supply some insight for the development of visiblelight-driven Bi 2 MoO 6 -based photocatalysts applicable to both environmental remediation and biomass-derived chemical transformation.
