壳聚糖修饰镍基催化剂用于二甲基紫脲酸加氢反应的研究

Study on Chitosan-Modified Nickel-based Catalysts Applied in Hydrogenation of Dimethyl Aminoureazinic Acid

采用金属诱导化学镀法制备了负载型NiB/CS/EVg、Ni/CS/Al2O3催化剂,将其用于二甲基紫脲酸加氢反应。结果表明,壳聚糖修饰的催化剂能较好的适应该反应。壳聚糖改性后催化剂的稳定性提高。

The supported NiB/CS/Evg and Ni/CS/Al2O3 catalysts were prepared by metal inducing electroless plating method and their catalytic activities were measured through hydrogenation of dimethyl aminoureazinic acid. The results showed that these supported catalysts were accesibale to this hydrogenation reaction. The stabilities of catalysts were improved because of chitosan - modified supporters.
