Developing efficient CO₂ reduction catalysts is essential not only for artificial photosynthesis but also for solving the energy crisis and global warming problems. We have successfully prepared a heterostructure of iron phosphide (FeP) modified polymeric carbon nitride (CN), which was used as a noble-metal-free photocatalyst for CO₂ reduction. The optimized FeP/CN composite displays a maximum CO evolution rate of 5.19 μmol g⁻¹ h⁻¹, which is 5.5 times that of pristine CN. FeP nanoparticles effectively facilitate the charge separation and play the role of active sites for CO₂ photoreduction. This work provides an active FeP/CN nanocomposite photocatalyst highly potential for CO₂ reduction.

开发有效的CO ₂还原催化剂不仅对于人工光合作用至关重要，而且对于解决能源危机和全球变暖问题都是必不可少的。我们已经成功地制备了磷化铁（FeP）改性的聚合氮化碳（CN）的异质结构，该结构被用作无贵金属的光催化剂，用于还原CO ₂。优化的FeP / CN复合材料显示出最大的CO释放速率为5.19μmolg ^-1  h ^-1，是原始CN的5.5倍。FeP纳米颗粒有效地促进了电荷分离并发挥了CO _2光还原活性位点的作用。这项工作提供了一种活性高的FeP / CN纳米复合光催化剂，具有很高的CO ₂潜力。 减少。
