The construction of direct Z-scheme heterojunctions is an effective method to overcome the shortcomings of single-component or conventional heterogeneous photocatalysts for photocatalytic CO<sub<2</sub< (carbon dioxide) reduction. In this work, a composite photocatalyst of narrow-gap SnS<sub<2</sub< and stable oxide Bi<sub<2</sub<WO<sub<6</sub< were prepared by a simple hydrothermal method. The combination of Bi<sub<2</sub<WO<sub<6</sub< and SnS<sub<2</sub< narrows the bandgap, thereby broadening the absorption edge and increasing the absorption intensity of visible light. Photoluminescence, transient photocurrent, and electrochemical impedance showed that the coupling of SnS<sub<2</sub< and Bi<sub<2</sub<WO<sub<6</sub< enhanced the efficiency of photogenerated charge separation. The experimental results show that the electron transfer in the Z-scheme heterojunction of SnS<sub<2</sub</Bi<sub<2</sub<WO<sub<6</sub< enables the CO<sub<2</sub< reduction reactions to take place. The photocatalytic reduction of CO<sub<2</sub< is carried out in pure water phase without electron donor, and the products are only methanol and ethanol. By constructing a Z-scheme heterojunction, the photocatalytic activity of the SnS<sub<2</sub</Bi<sub<2</sub<WO<sub<6</sub< composite was improved to 3.3 times that of pure SnS<sub<2</sub<.

abstract	Using sunlight to convert CO<sub<2</sub< into solar fuel is an ideal solution to both global warming and the energy crisis. The construction of direct Z-scheme heterojunctions is an effective method to overcome the shortcomings of single-component or conventional heterogeneous photocatalysts for photocatalytic CO<sub<2</sub< (carbon dioxide) reduction. In this work, a composite photocatalyst of narrow-gap SnS<sub<2</sub< and stable oxide Bi<sub<2</sub<WO<sub<6</sub< were prepared by a simple hydrothermal method. The combination of Bi<sub<2</sub<WO<sub<6</sub< and SnS<sub<2</sub< narrows the bandgap, thereby broadening the absorption edge and increasing the absorption intensity of visible light. Photoluminescence, transient photocurrent, and electrochemical impedance showed that the coupling of SnS<sub<2</sub< and Bi<sub<2</sub<WO<sub<6</sub< enhanced the efficiency of photogenerated charge separation. The experimental results show that the electron transfer in the Z-scheme heterojunction of SnS<sub<2</sub</Bi<sub<2</sub<WO<sub<6</sub< enables the CO<sub<2</sub< reduction reactions to take place. The photocatalytic reduction of CO<sub<2</sub< is carried out in pure water phase without electron donor, and the products are only methanol and ethanol. By constructing a Z-scheme heterojunction, the photocatalytic activity of the SnS<sub<2</sub</Bi<sub<2</sub<WO<sub<6</sub< composite was improved to 3.3 times that of pure SnS<sub<2</sub<.
