Synthesis and photocatalytic properties of core–shell structured α-Fe2O3@SnO2 shuttle-like nanocomposites

Visible‐Light Photocatalytic Degradation of Methylene Blue Using SnO2/α‐Fe2O3 Hierarchical Nanoheterostructures

“…As shown in Figure 1 (Figure S12), which is correlated with the complexed band configuration of the SnO 2 /aFe 2 O 3 SHNHs. On the basis of the Anderson model, [7,35] a "staggered" type-II band configuration at the interface of the SnO 2 / a-Fe 2 O 3 SHNHs is proposed (Figure 5 A). This type-II band alignment can give an efficient improvement in the separation of photogenerated electron-hole pairs.…”

“…[4,5] The solution route is considered as a less costly, mild, easily controllable, and high-throughput approach for the fabrication of nanomaterials, with the advantage that it is a simple, low-temperature, and environmentally friendly method. [6][7][8] As a narrow-bandgap ( % 1.9-2.2 eV) n-type semiconductor with a wide photoelectrochemical response reaching the visible-light region, [9][10][11][12][13] a-Fe 2 O 3 has been studied intensively as an electrochemical photocatalyst. Because of its short hole-diffusion length (2-4 nm), [12] photogenerated electron-hole pairs cannot easily be separated in a-Fe 2 O 3 .…”

Rapid switching and ultra-responsive nanosensors based on individual shell–core Ga2O3/GaN:O @SnO2 nanobelt with nanocrystalline shell in mixed phases

“…[25] Zhu et al, however, reported about the growth of a-Fe 2 O 3 @SnO 2 shuttle-like nanocomposites by a simple solvothermal method. [26] In an attempt, Chang et al [27] synthesized zigzag Ga 2 O 3 /GaN:O x heterogeneous nanowires and studied their gas sensing characteristics. As a further approach in this context, Park et al.…”

Characterization and photocatalytic performance of SnO2–CNT nanocomposites

“…Tin oxide (SnO 2 ) is one of the most attractive photocatalysts due to its high physicochemical stability, low cost, and lack of toxicity [12][13][14]. It is an n-type transparent semiconductor with a rutile structure.…”
