“…Regarding the carbonaceous supports (carbon nanotubes, biochar, g-C 3 N 4 , activated carbon and graphene), graphene derivatives have been successfully used for catalyst immobilization due to catalytic activity, stability and reusability [11,71]. Graphene, a two-dimensional carbon allotrope, is characterized by an extremely large specific surface area (~2360 m 2 /g), high thermal/electrical conductivity, strong mechanical and chemical stability, strong electron transfer capacity and simple synthesis from graphite by chemical procedure [72].…”

“…Despite their low cost, some persistent organic pollutants are not susceptible to direct biological treatment [6], and thus, physical and chemical methods are considered a preferable approach for removing heavy metals and recalcitrant pollutants [10]. Physical processes are categorized into adsorption, reverse osmosis, sedimentation and membrane-filtration-based processes, whereas the physicochemical methods mainly include electrolysis, Fenton-based processes, photolysis, ozonation and sonolysis [11,12]. These widely used technologies are commonly called advanced oxidation processes (AOPs).…”

Nowadays, water pollution is one of the most dangerous environmental problems in the world. The presence of the so-called emerging pollutants in the different water bodies, impossible to eliminate through conventional biological and physical treatments used in wastewater treatment plants due to their persistent and recalcitrant nature, means that pollution continues growing throughout the world. The presence of these emerging pollutants involves serious risks to human and animal health for aquatic and terrestrial organisms. Therefore, in recent years, advanced oxidation processes (AOPs) have been postulated as a viable, innovative and efficient technology for the elimination of these types of compounds from water bodies. The oxidation/reduction reactions triggered in most of these processes require a suitable catalyst. The most recent research focuses on the use and development of different types of heterogeneous catalysts, which are capable of overcoming some of the operational limitations of homogeneous processes such as the generation of metallic sludge, difficult separation of treated water and narrow working pH. This review details the current advances in the field of heterogeneous AOPs, Fenton processes and photocatalysts for the removal of different types of emerging pollutants.

“…This model assumes that adsorption occurs in three stages involving surface reaction, lm diffusion, and pore diffusion. In various previous reports, adsorption of FLX on low-cost biochar followed pseudo-second-order model 50 and the adsorption of dyes such as Malachite Green, MB and Rhodamine B also followed the same model.

The generation of sewage wastewater is unavoidable due to the continual increase in the global population that paves the way to appropriate disposal management. Sewage wastewater treatment and consequent generation of sewage sludge (SS) are well connected with global environmental issues. Upon risk assessment on different SS disposal methods, converting SS into biochar, that is, sewage sludge biochar, can be recommendable management. It is well‐proven for excellent positive impacts, such as nutrient enhancement, and healthier plant growth, and mitigates the emissions of greenhouse gases while amending with agricultural soil. However, the outcome features of SSB significantly vary with pyrolysis temperature and its elemental constituents. In addition, many studies revealed that the process temperature is key to responsible for the desirable properties and functioning of SSB. In this context, many countries support to the development of a futuristic strategy for SS management toward producing SSB and its utilization in agriculture. This review compiles studies into SSB's ability to promote a sustainable effect on the total worldwide output volume. Furthermore, the generation of SSB is also analyzed from a socioeconomic standpoint in relation to other common SS disposal management strategies.
