原位捕获Pd簇的超薄氢石墨炔纳米片及其污染物降解性能
Ultrathin hydrogen-substituted graphdiyne nanosheets containing pd-clusters used for the degradation of environmental pollutants
摘要
Abstract
Graphdiyne(GDY)and its derivatives have been considered ideal supporting materials for nanoscale active particles because of their unique atomic and electronic struc-ture.An efficient bi-metal Cu-Pd catalyst was added to pro-duce the uniform deposition of Pd nano-clusters with an av-erage size of～0.95 nm on hydrogen-substituted GDY(H-GDY)nanosheets.With the assistance of NaBH4,the result-ing Pd/H-GDY was very effective in the degradation of 4-ni-trophenol(4-NP),whose conversion was sharply increased to 97.21%in 100 s with a rate constant per unit mass(k`)of 8.97×105 min-1 g-1.Additionally,dyes such as methyl or-ange(MO)and Congo red(CR)were completely degraded within 180 and 90 s,respectively.The Pd/H-GDY main-tained this activity after 5 reduction cycles.These results highlight the promising performance of Pd/H-GDY in catalyzing the degradation of various pollutants,which is attributed to the combined effect of the large π-conjugated structure of the H-GDY nanosheets and the evenly distributed Pd nanoclusters.关键词
