Constructing 1D/2D heterojunction photocatalyst from FeSe 2 nanorods and MoSe 2 nanoplates with high photocatalytic and photoelectrochemical performance

“…The nitrogen adsorption desorption and pore diameter distribute curves of MS, FS, and MFS3 are shown in Figure 3. 18 After loading FeSe 2 , the BET-specific surface area of the composite photocatalysts decreased slightly. MS has a BETspecific surface area of 27.5 m 2 /g, while that of FS is 11.3 m 2 /g.…”

“…MS has a BETspecific surface area of 27.5 m 2 /g, while that of FS is 11.3 m 2 /g. 18 After loading FeSe 2 , the BET-specific surface area of the composite photocatalysts decreased slightly. The BET specific surface area of MFS1~MFS4 slowly reduced from 27.2 to 24 m 2 /g for the composited FeSe 2 has a relatively lower BET specific surface area that resulted in the decline of specific area of composites.…”

“…The combustion product is water and free of pollution. [16][17][18][19][20][21][22][23][24][25][26][27][28] Compared with metal sulfides, metallic selenides have narrower bandgap and higher carrier mobility, but they are rarely studied. 1 In the process of photoelectrochemical hydrogen production, the most important is the choice of photocatalysts.…”

“…15 Among them, metal sulfides such as SnS 2 , MoS 2 , MnS, In 2 S 3 , and ZnS have narrow bandgap and high carrier mobility, and their photoelectrochemical properties are obviously better than those of metal oxides. [16][17][18][19][20][21][22][23][24][25][26][27][28] Compared with metal sulfides, metallic selenides have narrower bandgap and higher carrier mobility, but they are rarely studied. MoSe 2 is a two-dimensional material with a bandgap of only 1.7 eV, capable of absorbing sunlight at all UV-visible wavelengths.…”

Fabrication of magnetic and recyclable In2S3/ZnFe2O4 nanocomposites for visible light photocatalytic activity enhancement

“…Particularly, as a typical III-VI group sulfide with a band gap of ∼2.0 eV [5][6][7], indium sulfide (In 2 S 3 ) has been considered as a sort of promising visible-light photocatalyst [8,9]. On account of its excellent intrinsic optoelectronic properties [10,11], favorable photostability [12], superior physical and chemical characteristics as well as low toxicity [8], it can be used to decompose organic contaminants and destroy bacteria for wastewater remediation and to split water for clean energy generation [13,14]. Nevertheless, similar to other narrow-band gap semiconductor photocatalysts, the efficiency of In 2 S 3 was far from satisfaction owing to the rapid recombination of photoexcited charge carriers.…”
