▎ 摘　　要

Graphite is the typical precursor used to fabricate graphene materials; however, other waste resources can also potentially synthesize graphene materials. Researchers have successfully exploited a wide variety of trash to produce graphene materials. The present study rigorously analyzed and critically discussed the suitability of various carbonaceous waste precursors after evaluating the quality of fabricated graphene materials. The pertinent studies on characterization techniques and the applications of fabricated graphene materials in water and wastewater treatment have also been highlighted. Additionally, the synthesis routes have been evaluated critically based on several parameters, such as the toxicity of the chemicals employed, time consumption, quality of product, costs, etc. An in-depth investigation of the sustainable fabrication of graphene materials using carbonaceous waste is required. As a result, this research will provide far-flung information and the research gaps in identifying prospective wastes for the large-scale production of graphene materials suitable for water and wastewater treatment applications.
