“…Distinct species to form the layered Dion-Jacobson materials AB 2 Nb 3 O 10 also play an essential role in the physical properties of the material and especially in their photocatalytic performance. From this point of view, Kulischow et al investigated a family of layered Dion-Jacobson perovskite-type materials AB 2 Nb 3 O 10 (A = K, Rb, Cs and B = Ca, Sr, Ba) and their photocatalytic activity for hydrogen production [38]. Seven different niobate were prepared by the molten salt method mixing BCO 3 or B(NO 3 ) 2 , (B = Ca, Sr, Ba), Nb 2 O 5 , A 2 CO 3 with ACl (A = K, Rb, Cs), and at specific reaction temperatures (750-1200 • C).…”

The search for renewable and clean energy sources is a key aspect for sustainable development as energy consumption has continuously increased over the years concomitantly with environmental concerns caused by the use of fossil fuels. Semiconductor materials have great potential for acting as photocatalysts for solar fuel production, a potential energy source able to solve both energy and environmental concerns. Among the studied semiconductor materials, those based on niobium pentacation are still shallowly explored, although the number of publications and patents on Nb(V)-based photocatalysts has increased in the last years. A large variety of Nb(V)-based materials exhibit suitable electronic/morphological properties for light-driving reactions. Not only the extensive group of Nb2O5 polymorphs is explored, but also many types of layered niobates, mixed oxides, and Nb(V)-doped semiconductors. Therefore, the aim of this manuscript is to provide a review of the latest developments of niobium based photocatalysts for energy conversion into fuels, more specifically, CO2 reduction to hydrocarbons or H2 evolution from water. Additionally, the main strategies for improving the photocatalytic performance of niobium-based materials are discussed.

“…Especially, 2D Ti/Nb metal oxide (TNMO)‐based compounds have attracted increasing attention as the contained octahedral structure of Ti 4+ ‐based TiO 6 and/or Nb 5+ ‐based NbO 6 , which can be facilely modified. The pristine 2D TNMOs can be mainly classified into three types: (1) wide‐bandgap photocatalysts with an ion‐exchangeable property, such as KTiNbO 5 , K 4 Nb 6 O 17 , KNb 3 O 8 , Ca 2 Nb 2 TaO 10 , CsTi 2 NbO 7 , Na 2 Ti 3 O 7 , K 2 Ti 4 O 9 , K 2 CaNaNb 3 O 10 , AB 2 Nb 3 O 10 (A = K, Rb, Cs and B = Ca, Sr, Ba), et al; (2) some visible‐light‐response 2D photocatalysts, such as, SnNb 2 O 6 , La 2 Ti 2 O 7 , Bi 3 NbO 7 , et al; (3) 2D TNMO‐based nanosheets (NSs), including 2D TiO 2 NSs …”

2D titanium/niobium (Ti/Nb) metal oxide (TNMO)‐based compounds have attracted increasing attention due to the fact that the contained octahedral structure of Ti4+‐based TiO6 and/or Nb5+‐based NbO6 can be facilely modified so as to achieve an enhanced photocatalytic performance for environmental remediation and energy conversion. Herein, the different synthetic methods for the construction of various 2D TNMO‐based photocatalysts are presented. Many basic principles, such as nanostructure design, doping, and construction of heterojunctions, are introduced to enhance the photocatalytic performance of 2D TNMO compounds. The relationship between the photocatalytic performance and regulation methods is also described. Furthermore, the photocatalytic applications of 2D TNMO‐based materials are discussed, including H2 generation, removal of pollutants, CO2 reduction, nitrogen photofixation, disinfection, and organic synthesis. Finally, the challenges and future development of 2D TNMO‐based materials are also discussed.

“…These blocks are separated by layers of A 0 cations. Their unique structure leads to many interesting properties, making them of interest for many applications, including for solar cells, 1,2 water splitting 3,4 and ferroelectrics. [5][6][7] It is known that DJ phase materials can be exfoliated into nanosheets due to the large interlayer spacing and weak bonding of the A 0 layers.…”
