PPECu nanowires were synthesized and the structure was explored. It was a metal organic polymer self-assembled by copper and phenylacetylene coordination and a p-type semiconductor material with the band gap of 2.48 eV. PPECu nanowires have excellent film-forming properties and exhibit hydrophobic properties. The photocurrent of PPECu was 10 times higher than that of g-C3N4 under the same conditions. The photoelectric conversion efficiency was 4.08% at 410 nm. It can activate molecular oxygen to produce superoxide radicals under visible light and the photocatalytic degradation of phenol and 2,4-DCP activity was 2.52 and 3.85 times higher than g-C3N4. Therefore, PPECu has a good potential at the application in the photoelectric conversion and photocatalytic degradation of pollutants.

自组装的聚合物苯基乙炔铜纳米线在可见光下的光电化学和光催化性能

合成了PPECu纳米线,并研究了其结构。它是通过铜和苯乙炔配位而自组装的金属有机聚合物,是带隙为2.48 eV的p型半导体材料。PPECu纳米线具有出色的成膜性能,并表现出疏水性能。在相同条件下,PPECu的光电流是gC 3 N 4的10倍。410nm处的光电转换效率为4.08%。它可以在可见光下活化分子氧以产生超氧自由基,苯酚的光催化降解和2,4-DCP活性分别是gC 3 N 4的2.52和3.85倍。。因此,PPECu在污染物的光电转化和光催化降解中具有广阔的应用前景。
