With the increase of industrialization, there is an urgent need for developing technologies to detect and remove toxic pollutants from water bodies. The pollutants are often released to the environment due to the consumption of raw materials that are necessary for the production of technological goods (such as chemical and pharmaceutical compounds, metals, and alloys or foods). Amongst all the remediation techniques, adsorption is considered as one of the preferred techniques, due to its fast and efficient removal of contaminants. Novel materials, which are engineered for selective and responsive water remediation, have also recently revealed a strong potential in the detection of pollutants. Here, current trends of silica-graphene (SG) porous composites for the removal of oils, organic solvents, heavy metals, and dyes are reviewed in detail. Insights on the modifications of composites to enhance their sorption performance have been highlighted. In addition, the detection of pollutants using porous SG nanocomposites is also critically reviewed. Overall, SG composites reveal a strong potential as nanostructure materials with improved efficiency for environmental-based applications.
随着工业化的发展，迫切需要开发技术来检测和去除水体中的有毒污染物。由于生产技术产品（如化学和制药化合物、金属和合金或食品）所需的原材料的消耗，污染物经常被释放到环境中。在所有修复技术中，由于其对污染物的快速高效去除，吸附被认为是首选技术之一。最近，为选择性和响应性水修复而设计的新型材料在污染物检测方面也显示出了强大的潜力。在这里，详细回顾了用于去除油、有机溶剂、重金属和染料的硅石-石墨烯（SG）多孔复合材料的当前趋势。强调了对复合材料进行改性以提高其吸附性能的见解。此外，还批判性地回顾了使用多孔 SG 纳米复合材料检测污染物的情况。总的来说，SG 复合材料作为具有改进的基于环境的应用效率的纳米结构材料具有很大的潜力。
