Rational construction of MXene-derived TiO2/CoNiO2 dual-site S-scheme heterojunction for boosting C–C coupling toward efficient photocatalytic CO2-to-C2H4 conversion

Key Points

• Enhanced C–C coupling observed with the dual-site heterojunction, indicating improved photocatalytic efficiency.
• The TiO2/CoNiO2 heterojunction demonstrates a significant increase in CO2-to-C2H4 conversion rates, achieving notable performance metrics.
• Analysis included photocatalytic activity measurements under visible light, confirming the effectiveness of the S-scheme design.
• This method may enable more efficient CO2 conversion technologies, but further assessment of long-term stability is required.
