Advanced oxidation technology of persulfate is a new method to degrade wastewater. As the economy progresses and technology develops, increasingly more pollutants produced by the paper industry, printing and dyeing, and the chemical industry are discharged into water, causing irreversible damage to water. Methods and research directions of activation persulfate for wastewater degradation by a variety of iron-based catalysts are reviewed. This review describes the merits and demerits of advanced oxidation techniques for activated persulfate by iron-based catalysts. In order to promote the development of related research work, the problems existing in the current application are analyzed.

“…The magnetic nature of this MBC catalyst facilitates the separation during recycling CoFe 2 O 4 NPs loaded BC having strong magnetic property, graphitized structure and rich porosity which can be used as an activator for peroxymonosulfate to degrade bis-phenol A. The synergistic effect between CoFe 2 O 4 and graphitized structure is responsible for superior catalytic activity and reusability of MBC after five consecutive reaction cycles with no considerable loss of Co and Fe ions [110]. Organic compounds are considered as role models of pollutants if they are not degraded properly.…”

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) epidemic has become an extraordinary medical challenging issue that caused severe negative impacts on population health and the world economy. The epidemic has completely engulfed the human civilization on a large scale. Therefore, the development of some promising, cheap, and eco-friendly drugs is required for the treatment of SARS-CoV-2. Recently, dexamethasone (DMs), a corticosteroid medication has a wide therapeutic application including against SARS-CoV-2. DMs has been found useful in controlling the damaging effect of cytokines as well as it's over production in various critically ill patients with SARS-CoV-2 but some drawbacks of DMs were also reported in literatures. The complex chemical synthesis of DMs has generated abundant amounts of waste products that affect the yield of DMs along with its cost. Hence, to tackle the above explained issues of DMs, analogues of DMs have been required to synthesis by the green approach. So that it will be non-hazardous toward the body and easily available to mankind. Green synthesis of DMs analogue scaffold contains ionic liquid (IL) as both solvent and catalyst but a number of studies show that the extraction of IL from synthesis reaction is quite a difficult process. Hence, a supportive catalyst is required for easy extraction of IL from reaction mixture. Magnetic bio-char (MBC) and magnetic nano particles (MNP) are considered as promising candidates for the supportive catalyst with IL as they can easily extract from synthesis reaction via magnetic separation method. The sol-gel method provides an effective means to develop the eco-friendly biocatalysts MBC-IL and MNP-IL. Moreover, MBC-IL and MNP-IL are efficient to load numerous drugs and using in drug delivery system. Therefore, the present investigation provides an effective means to develop a cost-effective, non-hazardous biocompatible, and reusable catalyst with green principle approach for the synthesis of DMs as they are useful for the treatment of SARS-CoV-2 and similar types of disease.

“…Corn stalk sourced biochar was used by Liu et al [178] for the synthesis of CoFe 2 O 4 nanoparticles (average size,~100 nm) that were then used as activation catalysts with PMS for the oxidative degradation of bisphenol A and other common organic contaminant species (Figure 10). It was determined that the combination of biochar and cobalt ferrite was very effective for the removal of contaminants.…”

Water resources are of extreme importance for both human society and the environment. However, human activity has increasingly resulted in the contamination of these resources with a wide range of materials that can prevent their use. Nanomaterials provide a possible means to reduce this contamination, but their removal from water after use may be difficult. The addition of a magnetic character to nanomaterials makes their retrieval after use much easier. The following review comprises a short survey of the most recent reports in this field. It comprises five sections, an introduction into the theme, reports on single magnetic nanoparticles, magnetic nanocomposites containing two of more nanomaterials, magnetic nanocomposites containing material of a biologic origin and finally, observations about the reported research with a view to future developments. This review should provide a snapshot of developments in what is a vibrant and fast-moving area of research.
