About this Research Topic
With rapid development in both industry and agriculture, large amounts of waste has been generated as a consequence putting enormous strain on the environmental pollution problem and in turn ecological and physical health. To effectively scale these processes, it is imperative that waste is treated in a sustainable way. Recently, the area of materials has begun to propose diverse and practical solutions to this problem by identifying and isolating different waste materials with unique and valuable characteristics, for instance porous solids, catalysts and adsorbents using techniques such as chemical catalysis, enzymatic catalysis, reactions under autogenous pressure, wet impregnation, and incipient impregnation. This has opened up the door to the synthesis of novel added-value materials and their associated applications.
Within this type of novel waste materials, the novel carbonaceous materials including carbon nanotubes, carbon microspheres, graphene nanosheets, foam carbon and carbon microfibers have unique properties, such as tunable surface area and pore size, high chemical stability, cost-effective and facile preparation. Also of note is the activation processes, one of the most efficient methods to tailor the properties of carbon materials (especially the surface area, pore size, and distribution), that plays a critical role in achieving these valuable properties. Carbon materials have plenty of forms including graphite, graphene nanosheets, carbon nanotubes (CNTs), fullerenes, amorphous carbon, carbon nanofibers, foam carbon and carbon microspheres have attracted enormous attention due to their excellent chemical and thermal stability, high electric conductivity, and high mechanical strength.
In this Research Topic, researchers are invited to present their recent work on how waste materials, from a variety of origins (e.g scrap tires, scrap cables, scrap plastics, shredder waste, acidic sludge), have been shown to produce new materials with environmental benefit. For instance, the use of battery waste (where it has been possible to recover metals and compounds with high purity) has produced functional materials such as electrode materials in energy storage devices, catalysts, absorbents, magnetic materials, alloys. Additionally, we welcome papers that account for finding usage in the residual biomass used in the preparation of such special materials (such as aerogels, xerogels, cryogels, etc.) and their potential applications, as well as papers that address technologies used in their preparation.
Authors should frame their papers with waste as a starting material for production within the following, but not limited to, areas:
• Preparation of carbon and hydrocarbon materials from different waste materials including polymeric waste
• Characterization and application of new materials made from waste;
• Preparation of graphenes, graphene oxides, MOF's, aerogels, xerogels, cryogels
• Catalysts that involve waste material in the synthesis methods
