“…Of note, the constituent monomers originated from plastics depolymerization features high content of hydroxyl groups, which endows a good water‐solubility and thus favors the photocatalytic plastic transformation. To date, many researchers have paid their attention to decomposing recalcitrant pollutants (e.g., bisphenol A [BPA], phthalic acid esters [PAEs], and polycyclic aromatic hydrocarbons [PAHs]), owing to their possible side‐effects on the human body once released into the environment 109–112 . For example, BPA monomers extracted from food containers possibly led to abnormal physiological indexes after ingestion or absorption by humans (e.g., liver enzymes, fasting insulin, and serum total testosterone) 113 .…”

The accumulation of plastic wastes in landfills and the environment threatens our environment and public health, while leading to the loss of potential carbon resources. The urgent necessary lies in developing an energy‐saving and environmentally benign approach to upgrade plastic into value‐added chemicals. Artificial photosynthesis holds the ability to realize plastic upcycling by using endless solar energy under mild conditions, but remains in the initial stage for plastic upgrading. In this review, we aim to look critically at the photocatalytic conversion of plastic wastes from the perspective of resource reutilization. To begin with, we present the emerging conversion routes for plastic wastes and highlight the advantages of artificial photosynthesis for processing plastic wastes. By parsing photocatalytic plastic conversion process, we demonstrate the currently available routes for processing plastic, including plastic photodegradation, tandem decomposition of plastic and CO2 reduction, selective plastic oxidation, as well as photoreforming of plastic. This review concludes with a personal perspective for potential advances and emerging challenges in photocatalytic plastic conversion.

“…Environmental remediation technologies for modified nanomaterials are based on the ability of certain materials or modifiers to adsorb or passivate metal contaminants. A large number of new efficient and economical DOM-modified nanomaterials have been developed and widely used in environmental remediation ( Dutta et al, 2022 ; Pratyush et al, 2022 ; Rajput et al, 2022 ). The role of HS in changing the surface properties, transport capacity, aggregation, and toxicity of nanomaterials has drawn the attention of researchers ( Khin et al, 2012 ; Tang et al, 2014 ).…”

Fulvic acid (FA) has been shown to play a decisive role in controlling the environmental geochemical behavior of metals. As a green and natural microbial metabolite, FA is widely used in environmental remediation because of its good adsorption complexation and redox ability. This paper introduces the reaction mechanism and properties of FA with metals, and reviews the progress of research on the remediation of metal pollutant by FA through physicochemical remediation and bioremediation. FA can control the biotoxicity and migration ability of some metals, such as Pb, Cr, Hg, Cd, and As, through adsorption complexation and redox reactions. The concentration, molecular weight, and source are the main factors that determine the remediation ability of FA. In addition, the ambient pH, temperature, metal ion concentrations, and competing components in sediment environments have significant effects on the extent and rate of a reaction between metals and FA during the remediation process. Finally, we summarize the challenges that this promising environmental remediation tool may face. The research directions of FA in the field of metals ecological remediation are also prospected. This review can provide new ideas and directions for the research of remediation of metals contaminants in sediments.

“…Whereas numerous "nano" forms of carbon are becoming increasingly popular over the years and are being vigorously explored more than ever around the world, which is certainly justified due to their incredible characteristics, one should not underestimate the astounding range of technological solutions that bio-based carbons can deliver [37][38][39][40]. Exclusively, the gigantic majority of porous carbons are considered those are cost-effective and display potential for environmental prominence.…”

Providing safe drinking water and clean water is becoming a more challenging task all around the world. Although some critical issues and limits remain unsolved, implementing ecologically sustainable nanomaterials (NMs) with unique features, e.g., highly efficient and selective, earth-abundance, renewability, low-cost manufacturing procedures, and stability, has become a priority. Carbon nanoparticles (NPs) offer tremendous promise in the sectors of energy and the environment. However, a series of far more ecologically friendly synthesis techniques based on natural, renewable, and less expensive waste resources must be explored. This will reduce greenhouse gas emissions and harmful material extraction and assist the development of green technologies. The progress achieved in the previous 10 years in the fabrication of novel carbon-based NMs utilizing waste materials as well as natural precursors is reviewed in this article. Research on carbon-based NPs and their production using naturally occurring precursors and waste materials focuses on this review research. Water treatment and purification using carbon NMs, notably for industrial and pharmaceutical wastes, has shown significant potential. Research in this area focuses on enhanced carbonaceous NMs, methods, and novel nano-sorbents for wastewater, drinking water, groundwater treatment, as well as ionic metal removal from aqueous environments. Discussed are the latest developments and challenges in environmentally friendly carbon and graphene quantum dot NMs.
