Here we demonstrate the synthesis of benzimidazolones from -phenylenediamines and carbon dioxide in the presence of gold nanoparticles supported on a composite material based on microcrystalline chitosan from shrimp shells and fibrous phosphosilicate (CS-FPS/Au). The results showed that the gold nanoparticles were stable with the P, N and O atoms of CS-FPS. The morphology and structure of FPS leads to a higher catalytic activity. The CS-FPS/Au NPs were thoroughly characterized using TEM, FESEM, TGA, FTIR, and BET.
在此，我们展示了在基于虾壳微晶壳聚糖和纤维状磷硅酸盐（CS-FPS/Au）的复合材料负载的金纳米颗粒存在下，由对苯二胺和二氧化碳合成苯并咪唑酮。结果表明，金纳米颗粒与CS-FPS的P、N和O原子稳定结合。FPS的形态和结构导致了更高的催化活性。使用透射电子显微镜（TEM）、场发射扫描电子显微镜（FESEM）、热重分析（TGA）、傅里叶变换红外光谱（FTIR）和比表面积分析（BET）对CS-FPS/Au纳米颗粒进行了全面表征。
