The recent discovery and synthesis of graphene materials have led to many applications in various fields such as medicine, energy and environment. Here, we review the synthesis, functionalization, properties and applications of graphene materials with focus on environmental applications such as detection and adsorption of pollutants, and photocatalysis. For instance, hybrid systems can detect pollutants at levels of 0.1 nM Pb²⁺, 5 nM Hg²⁺ and 0.3 μmol Cu²⁺ per L with a faster response time. Graphene-based materials have adsorption capacities ranging from 21 to 117.5 mg/g for metal ions, and from 1 to 827 mg/g for organic pollutants. Graphene oxide-based photocatalytic devices allow more than 95% of dye degradation.

最近石墨烯材料的发现和合成导致了在医学、能源和环境等各个领域的许多应用。在这里，我们回顾了石墨烯材料的合成、功能化、性能和应用，重点关注环境应用，如污染物的检测和吸附以及光催化。例如，混合系统可以以更快的响应时间检测每升0.1 nM Pb ²⁺、5 nM Hg ²⁺和 0.3 μmol Cu ²⁺水平的污染物。石墨烯基材料对金属离子的吸附能力为 21 至 117.5 mg/g，对有机污染物的吸附能力为 1 至 827 mg/g。基于氧化石墨烯的光催化装置允许超过 95% 的染料降解。
