Hexagonal nanoplates of high-quality γ-gallium oxide: controlled synthesis and good heterogeneous catalytic performance for thiophenes

Abstract

Hexagonal nanoplates of high-quality γ-gallium oxide were successfully synthesized by using a competitive and cooperative interaction model.

Dispersing TiO2 Nanoparticles on Graphite Carbon for an Enhanced Catalytic Oxidative Desulfurization Performance

“…25,26 For example, Wang et al prepared hexagonal nanoplates of high-quality gamma-gallium oxide (γ-Ga 2 O 3 ), which were further employed in ODS, and an excellent desulfurization performance was gained. 27 Our group reported the synthesis of oxygen-defective tungsten oxide and found that the variable valence induces a remarkably enhanced ODS activity. 28 Although numerous advantages of metal oxide catalysts have been achieved for ODS, an inevitable disadvantage is that the poor active-site exposure seriously limits the improvement of catalytic activity.…”

Synthesis, structure, magnetism and photocatalysis of α-Fe2O3nanosnowflakes

“…22,25,26 Recently, we noticed that PVP could play a key role in forming high-quality g-Ga 2 O 3 nanostructures by its binding to gallium ions and gallium complexes, since this binding has contributed to the decrease of primary particle formation, nucleation and microstructural growth of g-Ga 2 O 3 in mild hydrothermal conditions. 19 This nding encourages the further use of this new method in the treatment of the formation of a-Fe 2 O 3 nanostructures.…”

“…Based on our recent work on analyzing various interactions including precipitate, coordination and binding equilibria in aqueous solution, 19 we consider that the contribution of PVP to the construction of nanoparticles of a-Fe 2 O 3 can be explained as the presence of the binding interaction between the PVP chain and the octahedral complex of Fe(II). The results of several independent experiments conrm this possibility.…”

“…In such a situation, we have successful experiences in the design and synthesis of gallium oxide nanomaterials using a coordination/ binding route. 19,20 Thus, it is the main aim of this work to present a new supramolecular project for the generation of snowake-like a-Fe 2 O 3 nanoparticles.…”

2D Materials Based on Main Group Element Compounds: Phases, Synthesis, Characterization, and Applications

“…These can enhance the photocatalytic efficiency and stability of water splitting compared with bulk γ‐Ga 2 O 3 . [ 87 ] Other applications such as solar‐blind photodetectors [ 88 ] and heterogeneous catalytic performances for thiophenes [ 89 ] were also based on hydrothermally prepared γ‐Ga 2 O 3 .…”
