“…It is possible that the positive effect of the catalyst can be attributed to the decomposition of H 2 O 2 to generate more ·OH radicals. Nevertheless, the degradation efficiency of MB started to decrease when the concentration of H 2 O 2 exceeded 40 mM, which may be mainly due to the self-scavenging effect of ·OH radicals caused by excess hydrogen peroxide, as described in eqs and …”

The functionalized design of metal−organic frameworks (MOFs) has been rapidly developed in the last 20 years, and its broad applicability has been demonstrated in many fields. MOFs with desired functions can be assembled using predesigned organic linkers with specific metal nodes, which possess the ordered functional sites and open structures. Although a large number of carboxylic acid junctions have been used to construct MOFs, it is still a great challenge to realize their multifunctionality. In particular, there is a relative lack of research on MOFs as direct photocatalysts, which require not only abundant active sites and open structures but also adsorption groups and effective electron−hole separation performance. To this end, MOFs constructed from the carboxylic acid ligands derived from lophine-based derivatives and copper ions were deliberately used as a photocatalyst, and then, their application in dye degradation and aromatic alcohol conversion was investigated. In addition, in combination with the abundant Lewis sites of copper ions and imidazole sites, the material shows not only the adsorption and separation of C 2 series and dyes but also the application of dye degradation and conversion of aromatic alcohols under illumination conditions. The corresponding results fully illustrate that the MOF constructed by using lophine derivatives can be an effective way to prepare photocatalysts. The subsequent research ideas will focus on designing a series of MOFs constructed with multilinked moieties of lophine groups and exploring their application strategies in the field of photocatalysis.

“…Cobalt, cerium, manganese, copper, and another redox metal oxides were utilized as catalysts to investigate their reactivity to H 2 O 2 degradation into ˙OH in the Fenton-like degradation of organic pollutants. 212–215 Cerium oxides (CeO 2 ) (such as CeO 2 nanorod and CeO 2 nanocube) as heterogeneous Fenton-like catalysts have been attracted great interest for their catalytic oxidation applications. 216 Additionally, Ce-doped MOF and CuO/Al 2 O 3 are also efficient heterogeneous Fenton-like catalyst with high activity in Fenton-like oxidation of hazardous pollutants.…”

There has been a rapid increase in the usage of carcinogenic organic and inorganic compounds such as dyes, heavy metals, and phenols due to the rise in industrialization. Around 70% of the industrial effluents are dumped into the aquatic system without being treated where they pollute the usable water supply. These elements can also harm the human health by entering the food chain. According to the current population growth rate, 3.5 billion people are expected to face water scarcity by 2025. Therefore, the need to eliminate these pollutants is growing day by day. Nanobioremediation, a combination of bioremediation and nanotechnology is a competent way to remove contaminants from aquatic systems as it is a non-toxic, cost-effective, and less time-consuming approach. Nanotechnology has compelling capability, and thus, the applications of nanoparticles will escalate in the near future, and it will be a significant part of sustainable development. This review summarizes how various nanomaterials have the potential to degrade contaminants and how it can be used in the form of adsorbents, sensors, membranes, nano-catalysts, and nano-filters to remediate contaminants from marine systems. In addition to this, various limitations of nanobioremediation and the factors responsible for efficiency of nanomaterials are also discussed in this review paper.
