Enhanced interfacial charge separation via MnIn 2 S 4 /Zn 2 TiO 4 heterojunction for light-induced fuel production

Key Points

• The aim is to improve charge separation in a novel heterojunction to enhance carbon dioxide conversion to fuels.
• Constructed a 2D/1D MnIn2S4/Zn2TiO4 heterostructure through in situ growth.
• Examined the charge separation efficiency under UV-visible light.
• Analyzed the photoreduction of CO2 to value-added products.
• The heterojunction significantly improved charge separation efficiency.
• Efficient CO2 conversion to carbon products was achieved under illumination.
• The method exhibits promise for sustainable fuel production.
