As the bulk of solid waste from coal chemical industry, coal gasification fine slag (CGFS) mainly consists of aluminosilicates and residual carbon. Currently, the common transformation strategy for CGFS entails the preparation of porous materials. However, this method utilizes only a part of the effective components in the slag. Specifically, either the silicon is used to synthesize zeolites, or the porous carbon is obtained through intensified separation. Therefore, it is highly desirable to achieve the simultaneous utilization of silicon and carbon resources in CGFS. In this work, CGFS was used as a low-cost raw material to prepare the P-zeolite/carbon composite in situ. The composite was characterized via XRD, ²⁷Al and ²⁹Si NMR, SEM, FT-IR, and Raman technique. Furthermore, the adsorption removal of crystal violet onto the composite was studied. The adsorption capacity was as high as 625.00 mg g⁻¹, which was much larger than the CGFS and most reported adsorbents.

煤气化细渣（CGFS）是煤炭化学工业产生的大量固体废物，主要由铝硅酸盐和残留碳组成。当前，CGFS的通用转化策略需要制备多孔材料。但是，该方法仅利用炉渣中的一部分有效成分。具体地说，要么使用硅来合成沸石，要么通过强化分离获得多孔碳。因此，非常希望在CGFS中同时利用硅和碳资源。在这项工作中，CGFS被用作低成本原材料，原位制备了P-沸石/碳复合材料。通过XRD，²⁷ Al和²⁹对复合材料进行了表征Si NMR，SEM，FT-IR和Raman技术。此外，研究了结晶紫在复合材料上的吸附去除。吸附容量高达625.00 mg g ^-1，比CGFS和大多数报道的吸附剂大得多。
