Enhanced Photocatalytic Activity of BiVO<sub<4</sub</Bi<sub<2</sub<S<sub<3</sub</SnS<sub<2</sub< Heterojunction under Visible Light

Heterojunction photocatalysts have attracted a significant amount of attention due to their advantages over a single photocatalyst and, particularly, their superior spatial charge separation. Herein, the BiVO<sub<4</sub</Bi<sub<2</sub<S<sub<3</sub</SnS<sub<2...

Herein, the BiVO<sub<4</sub</Bi<sub<2</sub<S<sub<3</sub</SnS<sub<2</sub< heterojunction was synthesized via solvothermal synthesis with different ratios of BiVO<sub<4</sub< to SnS<sub<2</sub<. The photodegradation rate of the 0.03 BiVO<sub<4</sub</SnS<sub<2</sub< sample for rhodamine B removal is 2.3 times or 2.9 times greater than that of a single SnS<sub<2</sub< or BiVO<sub<4</sub<, respectively. The chemical bond between photocatalysts is confirmed by X-ray photoelectron spectroscopy (XPS), and the synchronized shift observed in binding energies strongly indicates the electron screening effect at the heterojunction. A Z-scheme model is proposed to explain charge transfer pathway in the system, in which the formation of Bi<sub<2</sub<S<sub<3</sub< plays a crucial role in the enhanced photocatalytic performance of the heterojunction.

abstract	Heterojunction photocatalysts have attracted a significant amount of attention due to their advantages over a single photocatalyst and, particularly, their superior spatial charge separation. Herein, the BiVO<sub<4</sub</Bi<sub<2</sub<S<sub<3</sub</SnS<sub<2</sub< heterojunction was synthesized via solvothermal synthesis with different ratios of BiVO<sub<4</sub< to SnS<sub<2</sub<. The photodegradation rate of the 0.03 BiVO<sub<4</sub</SnS<sub<2</sub< sample for rhodamine B removal is 2.3 times or 2.9 times greater than that of a single SnS<sub<2</sub< or BiVO<sub<4</sub<, respectively. The chemical bond between photocatalysts is confirmed by X-ray photoelectron spectroscopy (XPS), and the synchronized shift observed in binding energies strongly indicates the electron screening effect at the heterojunction. A Z-scheme model is proposed to explain charge transfer pathway in the system, in which the formation of Bi<sub<2</sub<S<sub<3</sub< plays a crucial role in the enhanced photocatalytic performance of the heterojunction.

Herein, the BiVO<sub<4</sub</Bi<sub<2</sub<S<sub<3</sub</SnS<sub<2</sub< heterojunction was synthesized via solvothermal synthesis with different ratios of BiVO<sub<4</sub< to SnS<sub<2</sub<. The photodegradation rate of the 0.03 BiVO<sub<4</sub</SnS<sub<2</sub< sample for rhodamine B removal is 2.3 times or 2.9 times greater than that of a single SnS<sub<2</sub< or BiVO<sub<4</sub<, respectively. The chemical bond between photocatalysts is confirmed by X-ray photoelectron spectroscopy (XPS), and the synchronized shift observed in binding energies strongly indicates the electron screening effect at the heterojunction. A Z-scheme model is proposed to explain charge transfer pathway in the system, in which the formation of Bi<sub<2</sub<S<sub<3</sub< plays a crucial role in the enhanced photocatalytic performance of the heterojunction.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">BiVO<sub<4</sub</Bi<sub<2</sub<S<sub<3</sub</SnS<sub<2</sub< heterojunction</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">visible light</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Z-scheme</subfield></datafield><datafield tag="653" ind1=" " ind2="0"><subfield code="a">Chemical technology</subfield></datafield><datafield tag="653" ind1=" " ind2="0"><subfield code="a">Chemistry</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">Takaya Ogawa</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">Hideyuki Okumura</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="0" ind2=" "><subfield code="a">Keiichi N.
