Efficient Photocatalytic Degradation of RhB by Constructing Sn3O4 Nanoflakes on Sulfur-Doped NaTaO3 Nanocubes

“…All the diffraction peaks can be readily indexed as a pure perovskite NaTaO 3 with a monoclinic structure (JCPDS No. 74-2478) [10,12], which can facilitate the separation of photo-induced electron-hole pairs. As has been reported, NaTaO 3 may exist in three polymorphs, which are the orthorhombic, cubic, and monoclinic phases [10,12].…”

“…Among these, ABO 3 perovskite-type oxides have been widely studied, due to their high performance in photocatalytic reactions, such as with overall water splitting and the photodegradation of organic pollutants, which provide a potential approach to solve our urgent energy and environmental problems [8,9]. Sodium tantalite (NaTaO 3 ) is a prominent ABO 3 perovskite-like oxide with a high performance in photocatalytic reactions, including abundance, photochemical stability, photodegradation of organic pollutants, water splitting, and low environmental impact, which attracts a lot of attention for its favorable layered structure and distinctive separation effectiveness in charge separation [10][11][12][13][14][15][16][17][18][19][20]. Hence, NaTaO 3 -based photocatalysts can intrinsically decrease the recombination rate of photo-induced carriers and promote the efficiency of photocatalytic systems.…”

“…Moreover, NaTaO 3 is a new type of wide bandgap semiconductor material, which has a bandgap of about 4.0 eV at room temperature [10]. To enhance the photocatalytic performance, metal or non-metal ions doped with NaTaO 3 (dopants: Sr 2+ [15,17], La 3+ [20,21], Ba 2+ [22], Ca 2+ [23], N or S [12,23]) or semiconductors loaded on NaTaO 3 , such In 2 S 3 [10], WO 3 [11], NiO [24], AgCl/Ag 2 O [25], g-C 3 N 4 [18,26], RuO 2 [27], and CdS [28] have been typically studied. These works were developed to improve the photocatalytic activity of NaTaO 3 -based materials.…”

Synthesis of g‐C3N4/InVO4 Semiconductor for Improved Photocatalytic and Photoelectrochemical Applications

“…No impurity or mixed phase was found in bulk or on the surface of the catalyst. Furthermore, it is wellknown that the improvement of photocatalytic performance of the composite material primarily depends on the effective separation of electron-hole pairs [66]. The difference in the photoelectrochemical activity of the catalysts was estimated through photocurrent and stability measurements of the materials.…”

Facile and rapid synthesis of a novel spindle-like heterojunction BiVO4 showing enhanced visible-light-driven photoactivity

“…Over the past decades, photocatalysts have attracted considerable attention in the eld of energy and environment. [1][2][3][4][5] Due to its high stability, low cost, non-toxicity and strong response to ultraviolet light, semiconductor oxide TiO 2 has been considered as an effective photocatalyst. However, the broad applications of TiO 2 are restricted because it can only utilize the ultraviolet (3-4%) fraction of the solar energy.…”
