“…The focus on improving the iron circulation kinetics lies in the design of new materials or systems to intensify Fe 3+ reduction. Electron-rich materials or systems can be used in electro-Fenton systems, such as metal sulfide based materials, zero-valence metals, chelating agents, carbon-based materials, − and emerging atomic hydrogen (H*) . Considering the price, stability, modification capability, sustainability, and environmental friendliness, carbon-based materials are excellent candidates as “electron shuttles” to facilitate electron transfer for Fe 3+ to regenerate Fe 2+ .…”

A large-scale deployment of electro-Fenton (EF) technology faces significant challenges, including the high cost of catalysts, complex electrode preparation, and limited energy utilization efficiency. Wood-derived carbon materials (WDCM) with three-dimensional (3D) structures have shown immense potential for energy storage and environmental remediation, due to their low cost and raw-material abundance, particularly the hierarchical structures for efficient mass transfer and ease of modification in electrochemical performance. The cost-effecitve and environmentally friendly nature as well as outstanding electrochemical performances make WDCM promising candidates for green and renewable electro-Fenton (EF) systems. In WDCM-based EF systems, it is crucial to explore suitable strategies for structural engineering and modification, enabling a better understanding of the relationships among structure, property, and performance. In this review, we present a perspective on wood redesign through structural engineering and chemical modification to regulate its mechanical properties and optimize mass transfer in electrochemical performance. Furthermore, we comprehensively discuss the recent advances and pathways of wood-based electro-Fenton systems. Finally, we provide a road map for the future challenges and opportunities of upscaling wood-based electro-Fenton systems for practical water treatments.

“…Generally, the specific surface area and functional groups of the adsorbent play a crucial role in the adsorption performance of HQ. Doping N and S atoms in activated carbon can not only enhance the hydrophilicity and stability but also promote electron transfer and chemical reactivity, resulting in higher adsorption capacity and catalytic performance. − Shengli et al successfully synthesized Phragmites australis activated carbon (PAAC) . The maximum adsorption capacity of PAAC for HQ reaches 156.25 mg·g –1 , which is mainly attributed to the high specific surface area and rich N and O functional groups.…”

Hydroquinone (HQ) in wastewater is of great concern, as it is harmful to human health and threatens the ecological environment. However, the existing adsorbents have low adsorption capacity for HQ. To improve the removal of HQ, N,Scodoped activated carbon-ZIF-67 (NSAC-ZIF-67@C) was synthesized in this study by in situ growth of ZIF-67 on N,S-codoped activated carbon (NSAC) and carbonization. The influence of pH, contact time, and initial concentration on the adsorption behaviors of NSAC-ZIF-67@C on HQ were investigated. Owing to the synergistic effect of abundant active sites and well-developed pore structure, the NSAC-ZIF-67@C achieved a prominent adsorption capacity of 962 mg•g −1 and can still retain high adsorption performance after 5 cycles for HQ, which is superior to that of reported other adsorbents. HQ adsorption follows the pseudosecond-order kinetics model (R 2 = 0.99999) and the Freundlich isotherm model. X-ray photoelectron spectroscopy (XPS) analysis before and after adsorption as well as density functional theory (DFT) calculation results showed that pyridinic-N-termini were conducive to the π−π interactions and hydrogen-bonding interactions. Therefore, the adsorption mechanisms of NSAC-ZIF-67@C on HQ involve pore filling, electrostatic attraction, π−π interaction, and hydrogen bonding. This study is expected to provide a reference for designing highly effective adsorbents for wastewater treatment.
