Abstract: A large amount of sewage and electronic-waste containing noble metals are discharged into nature every year, posing a serious threat to the natural environment and human health. Noble metal, as a non-renewable resource, has unique physical and chemical properties and is widely used in various fields, thus exacerbating the serious scarcity of noble metal resources. Therefore, the efficient recovery of noble metal from secondary resources, as an important research content, can not only protect the environment and human safety, but also obtain a large amount of noble metal resource. Adsorption is one of the most effective ways to separate noble metals. As the core of the adsorption method, the adsorption materials have attracted extensive attention from researchers. In recent years, researchers have devoted themselves to creating reusable and green adsorption materials with large adsorption capacity, fast adsorption rate, and high adsorption selectivity. Therefore, a large number of new adsorption materials have emerged. This article summarizes the research progress of new adsorbent materials in the past three years, focusing on the application for the separation and enrichment of noble metal, and five main types of nanomaterials, including carbon-based nanocomposite materials, polymer composite nanomaterials, new three-dimensional ordered materials, inorganic nanoparticles and their composite materials as well as biological adsorption materials. The structural characteristics, research ideas and practical applications of various materials are reviewed and discussed. Meanwhile, this article briefly outlines the prospects for the future development of adsorbent materials
