“…In addition, the presence of iron oxides can not only improve the adsorption capacity of biochar but also generate hydroxyl radicals under light, further promoting the degradation of CIP. Xiong et al [28] designed single atoms Fe 3 C from Enteromorpha-derived biochar, explaining that the mechanism enhanced peroxymonosulfate adsorption and activation on Fe 3 C, producing an efficient property toward nitenpyram removal. Biochar loaded with cobalt oxide has more surface chelating sites and polarities, as well as rich functional components, and has a strong affinity for metal ions through ion exchange, complexation, and electrostatic interaction.…”

The development of an efficient catalyst with excellent performance using agricultural biomass waste as raw materials is highly desirable for practical water pollution control. Herein, nano-sized, metal-decorated biochar was successfully synthesized with in situ chemical deposition at room temperature. The optimized BC-Cu (1:4) composite exhibited excellent peroxymonosulfate (PMS) activation performance due to the enhanced non-radical pathway. The as-prepared BC-Cu (1:4) composite displays a superior 99.99% removal rate for ciprofloxacin degradation (initial concentration 20 mg·L−1) within 40 min. In addition, BC-Cu (1:4) has superior acid-base adaptability (3.98~11.95) and anti-anion interference ability. The trapping experiments and identification of reactive oxidative radicals confirmed the crucial role of enhanced singlet oxygen for ciprofloxacin degradation via a BC-Cu (1:4)/PMS system. This work provides a new idea for developing highly active, low-cost, non-radical catalysts for efficient antibiotic removal.

Atomically dispersed metal and nitrogen co‐doped carbon catalysts (M‐N‐C) have been attracting tremendous attentions thanks to their unique MNx active sites and fantastic catalytic activities in advanced oxidation technologies (AOTs) for water remediation. However, precisely tailoring the microenvironment of active sites at atomic level is still an intricate challenge so far, and understanding of the non‐radical mechanisms in persulfate activation exists many uncertainties. In this review, latest developments on the microenvironment modulation strategies of atomically dispersed M‐N‐C catalysts including regulation of central metal atoms, regulation of coordination numbers, regulation of coordination heteroatoms, and synergy between single‐atom catalysts (SACs) with metal species are systematically highlighted and discussed. Afterwards, progress and underlying limitations about the typical non‐radical pathways from production of singlet oxygen, electron transfer mechanism to generation of high‐valent metal species are well demonstrated to inspire intrinsic insights about the mechanisms of M‐N‐C/persulfate systems. Lastly, perspectives for the remaining challenges and opportunities about the further development of carbon‐based SACs in environment remediation are also pointed out. It is believed that this review will be much valuable for the further design of active sites in M‐N‐C/persulfate catalytic systems and promote the wide application of SACs in various fields.

Urbanization and industrialization generate vast amounts of solid waste, posing significant threats to the biotic and abiotic components of the environment. Solid wastes-derived carbonaceous catalysts (SW-CCs) represent an effective strategy for resource utilization, and SW-CCs are gradually applied in environmental remediation and energy fields. However, the effects of the properties of SW-CCs on their catalytic activity remain inadequately understood. A comprehensive review of the applications of SW-CCs in environmental remediation and energy fields is yet to be achieved. It is necessary to systematically review the latest research progress of SW-CCs in environmental remediation and energy fields. First of all, this review summarizes the influences of various factors on the properties of SW-CCs and how these properties affect the catalytic activity. Subsequently, it explores the recent research progress and existing issues in the applications of SW-CCs in environmental remediation (persulfate activation, photocatalysis, and Fenton-like oxidation) and the energy sector (H2 production, biodiesel production, and CO2 conversion). Finally, future research prospects and recommendations are provided to facilitate further development and application of SW-CCs. This review offers new insights into the resource utilization of solid waste and the development of efficient and practical carbonaceous catalysts. Graphical Abstract
