采用一种新型的模板活化法制备了核壳结构的纳米多孔碳材料。以Fe 3 O 4纳米颗粒为结构模板，采用酸刻蚀和热活化法制备了三维Fe3O4@C@rGO复合材料.不同温度下的活化可以提供不同比表面积的材料。独特的纳米多孔结构具有大的表面积，是理想的吸附剂。以纳米多孔炭材料为吸附剂，对罗丹明B（Rh-B）进行了吸附性能研究。C@rGO-650比其他合成的吸附剂显示出更好的吸附性能。该吸附剂具有良好的可循环性，最大吸附容量可达14.8L·g-1。纳米多孔炭的优异吸附性能使其成为废水处理的理想材料。这种模板活化方法还可以拓宽核壳@片结构在构建纳米多孔碳中的潜在应用，这有助于解决相关的能源和环境问题。
A novel template-activation method was used to create nanoporous carbon materials derived from core–shells@rGO sheets. The carbon materials were prepared through an acid etching and thermal activation procedure with three-dimensional Fe3O4@C@rGO composites as precursors and Fe3O4nanoparticles as the structural template. The activation at different temperatures could provide materials with different specific surface areas. The unique nanoporous structures with large surface areas are ideal adsorbents. The nanoporous carbon materials were used as adsorbents for the removal of rhodamine B (Rh-B). C@rGO-650 illustrated better adsorption performance than the other synthesized adsorbents. It displayed good recyclability, and its highest adsorption capacity reached up to 14.8 L·g–1. The remarkable adsorption properties make nanoporous carbon a useful candidate for wastewater treatment. This template-activation method can also broaden the potential applications of core–shells@sheet structures for the construction of nanoporous carbon, which helps to resolve the related energy and environmental issues.
