Gold nano-supported thiocyanate absorbent and preparation method thereof

The invention relates to the fields of energy and chemical industry and specifically relates to a gold nano-supported thiocyanate absorbent and a preparation method thereof. By using the method for preparing the adsorbent by supporting thiocyanate on a gold nanoparticle array, CO2 absorption is realized and can be performed in both a gas phase and a liquid phase, and meanwhile, the catalytic effect for dual functions including CO2 conversion is achieved, namely, CO2 is recycled. The method has the advantages of simplicity in operation, short synthesis period and convenience for large-scale production in the industry and opens up a novel approach for absorbing CO2 in the air. 本发明涉及能源化工领域，具体涉及一种金纳米负载三聚硫氰酸盐吸收剂及其制备方法，将三聚硫氰酸盐负载到金纳米粒子阵列上的吸收剂，该方法实现对CO的吸收既可在气相进行也可在液相进行，同时还实现了CO转化的双功能的催化作用，即对CO进行资源化利用。该方法具有操作简单、合成周期短以及便于工业中大规模生产的优点，为吸收空气中的二氧化碳开辟了新途径。
