| 摘 要： | 以天然高分子壳聚糖为软模板,采用水热方法制备了纳米CdS空心微球,合成产物采用XRD,TEM,DRS等手段进行了表征.将合成的纳米CdS空心微球作为光催化剂,应用于可见光光催化制备低相对分子质量的壳聚糖的实验中.考察了光催化剂用量、壳聚糖浓度及反应气氛等因素对光催化氧化降解反应的影响,推测了CdS可见光催化制备低聚壳聚糖的机理.结果表明:可见光催化为低相对分子质量壳聚糖的可控制备提供了一条有效新途径.

| Abstract: | CdS hollow microsphere was successfully synthesized by the hydrothermal method with nature macromolecule chitosan as a "soft-template".Products were characterized by transmission electron microscope(TEM),field emission transmission electron microscope(FETEM),X-ray diffraction(XRD) and ultraviolet-visible diffuse reflection spectrum(UV-Vis-DRS),respectively.The synthesized CdS hollow microsphere was used as photocatalyst to synthesize low molecular weight chitosan.The effect of the mass fraction of chitosan ... |
