“…Cobalt is biologically toxic, which upon exposure may bring about solemn and sober menaces to mankind’s health, such as diarrhea, vomiting, cardiovascular disease, hyperglycemia, thyroid damage, and bone deformations 30 – 33 . Cobalt (II) compounds have been reported to cause DNA destruction, genetic alterations, and aneuploidy in living cells 34 . So, profuse research endeavors have been directed to develop novel cobalt-based heterogeneous catalysts for PMS activation with both high activity and robustness against metal leaching/agglomeration.…”

In this study, porous carbon nanocubes encapsulated magnetic metallic Co nanoparticles (denoted as Co@N-PCNC) was prepared via pyrolyzing ZIF-67 nanocubes precursor at 600 °C and characterized by various technologies. It was used to activate peroxymonosulfate (PMS) to degrade Congo red (CR) dye efficiently. Over 98.45% of 50 mg L−1 CR was degraded using 0.033 mM PMS activated by 75 mg L−1 Co@N-PCNC within 12 min. The free radical quenching experiments were performed to reveal the nature of the reactive oxygen species radicals generated throughout the catalytic oxidation of CR. The effects of common inorganic anions and the water matrix on CR removal were studied. Moreover, the results of the kinetic study revealed the suitability of the pseudo-first-order and Langmuir–Hinshelwood kinetic models for illustrating CR degradation using the Co@N-PCNC/PMS system. Ultimately, the Co@N-PCNC displayed good operational stability, and after five cycles, the CR removal rate can still maintain over 90% after 12 min.

“…Nanomaterials play an important role in the treatment of this polluted water with the help of characteristic particle size, high surface area, nano sorbet capacity, easier regeneration, chemical modification and hence nanocomposites are developed to overcome their aggregation (Arun et al, 2022;Tomar et al, 2020). Some of the nanocomposites and nanomaterials apart from being adsorbents are very active photo-nanocatalysts and can easily reduce the dyes and harmful organic compounds (Rana et al, 2023;Rana et al, 2023Rana et al, & 2024Tripathi et al, 2023). According to their physical, thermal, chemical, and electrical properties, carbon-based nanomaterials like graphene oxide, carbon nanotubes, and graphene are extensively used in applications such as waste water treatment, energy storage, drug delivery, diagnosis, adsorption, desorption, electronics and energy storage, etc.…”

Carbon nanomaterials are one of the most widely investigated nano-materials for the degradation of organic and inorganic pollutants like dyes and insecticides in an environmentally benign and that too in sustainable manner. The problems associated with the existing catalysts are related to their high band gap values and large particle sizes. In this review, the photocatalytic degradation of pollutants from industrial wastewater by using negligible amounts of carbon nanocatalysts has been covered as a solution to such types of problems. The photocatalytic activity of the carbon nanocomposites was reported to be affected by factors like particle size, nature of crystallinity, band gap, morphology and total surface area of the nanomaterials per unit mass. Despite various required optimizations, the carbon-containing nanomaterials such as carbon nanotubes, graphene, and metal oxide nanocomposites synthesized by using different methods have shown better photocatalytic activity as compared to others. This review article may open a new avenue to control water pollution efficiently and cost-effectively.
