Abstract

Poly(heptazine imide) (PHI), a carbon nitride polymer, is a highly efficient visible-light-driven photocatalytic material. We aimed to improve its photocatalytic performance for CO2 conversion. We prepared M-PHIs by encapsulating different metals (M = K, Li, Rb, and Na) and H-PHIs, in which the metal of each M-PHI was ion-exchanged with a proton. We evaluated their photocatalytic activities for CO2 conversion and found that Na-PHI and H-PHI, prepared from Na-PHI (H-PHI(NaCl)), showed more than twice the CO production efficiency of melon and other PHIs.

The high CO production efficiency of Na-PHI and H-PHI(NaCl) was attributed to their extremely smaller particle size compared with those of the other PHIs. By closely examining the synthesis conditions of Na-PHI, we have identified a method to intentionally synthesize M-PHI with small particle size. These results provide a new strategy for highly efficient CO2 conversion using PHI.

用于还原二氧化碳的金属聚(庚嗪亚胺)的光催化性能
聚(庚嗪亚胺)(PHI)是一种氮化碳聚合物,是一种高效的可见光光催化材料。我们的目标是提高其在二氧化碳转化方面的光催化性能。我们通过封装不同的金属(M = K、Li、Rb 和 Na)制备了 M-PHIs 和 H-PHIs,其中每种 M-PHI 的金属都与质子进行了离子交换。我们评估了它们转化二氧化碳的光催化活性,发现由 Na-PHI 制备的 Na-PHI 和 H-PHI(H-PHI(NaCl))的二氧化碳生成效率是甜瓜和其他 PHI 的两倍多。通过仔细研究 Na-PHI 的合成条件,我们找到了一种有意合成小粒径 M-PHI 的方法。这些结果为利用 PHI 高效转化二氧化碳提供了一种新策略。
