Climate change and uncertainty have significant impacts on the multi-regional energy system in terms of both supply and demand. In this study, a multi-regional energy model is developed based on the interval linear programming method. The model could not only describe the complex relationship between inter-regional interaction and energy transmission in detail, but also provide optimal schemes for regulating electricity generation mix, mitigating carbon emissions, and minimizing system cost. The results show that: (i) from 2021 to 2050, the proportion of fossil fuels in energy and electricity supply will show a decreasing trend, and the regional energy and electricity structure will be optimized;(ii) under the RCP4.5 scenarios, regional carbon emissions will peak around 2040 and show a decreasing trend after the peak, with a reduction of about 1.45%;(iii) the BTH region should bear additional costs of carbon emission reduction under the RCP4.5 scenarios, the total system cost is about 1.2 times of that under the RCP8.5 scenarios. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

As a highly developed region, Guangdong province has substantial industrial emissions. Its subtropical monsoon climate, characterized by abundant hydrothermal conditions, contributes to a substantial biomass potential. The adoption of potential biomass-based carbon dioxide removal (CDR) technologies, such as biochar, presents an opportunity to mitigate emissions and work towards carbon neutrality in the future. However, the current state of the land carbon balance and the CDR potential of biochar in Guangdong province remains unclear. We first calculated the land carbon balance based on inventory data. Then we estimated the CDR potential of biochar derived from agricultural residues, forestry residues, and bioenergy crops cultivated on marginal lands in Guangdong province using life cycle analysis (LCA). Results show that Guangdong province has not yet achieved carbon neutrality, with a net emission (carbon emissions remaining after offsetting by carbon sinks) of 925.63 Tg CO2e (CO2 equivalent, 1Tg = 106 t) in 2021. Emissions from energy consumption account for the highest proportion, contributing 83.8% of total emissions. In the highest biomass utilization scenario, the maximum CDR potential of biochar derived from all biomass types reaches 84.30 Tg CO2e yr-1, which could offset 9.11% of net carbon emissions in Guangdong province. Our findings provide crucial guidance for setting emission reduction targets and implementing effective mitigation strategies in Guangdong province under temperature warming.

Synergistic oxidation and coagulation of raw water by novel Fe(II)/sulfite process: A comparative study with peroxydisulfate and peroxymonosulfate

Journal of Hazardous Materials 2025年 493卷 138418页

作者： Lu, Jian Guo, Yuhao Pan, Minyuan Fu, Qi Zhou, Bin Zhang, Tianyang Peng, Zhu Shi, Jun He, Huan Zeng, Chao Xu, Bin State Key Laboratory of Pollution Control and Resource Reuse Key Laboratory of Yangtze Water Environment Ministry of Education College of Environmental Science and Engineering Tongji University Shanghai200092 China Shanghai Institute of Pollution Control and Ecological Security Shanghai200092 China

Latest findings demonstrate that the oxidative Fe(II)/sulfite (Fe(II)/S(IV)) process can rapidly generate iron particles, holding potential for coagulation while simultaneously removing emerging contaminants. Herein, we first report the synergistic oxidation-coagulation treatment of RW by Fe(II)/S(IV) process, and compare with traditional Fe-based coagulation (FeSO4, Fe2(SO4)3), Fe(II)/PDS and Fe(II)/PMS processes. Results revealed that the Fe(II)/S(IV) process outperformed traditional Fe-based coagulants, Fe(II)/PDS and Fe(II)/PMS in removing turbidity, UV254, and DOC. For emerging contaminants removal from RW, Fe(II)/PMS showed the highest efficiency, followed by Fe(II)/PDS, while Fe(II)/S(IV) was slightly less effective, it still demonstrated a significant improvement (40 %∼65 %) over traditional coagulation processes. Moreover, the Fe(II)/S(IV) process is the most effective in reducing DBPs formation (56 %∼86 %). Although Fe(II)/PDS and Fe(II)/PMS also significantly reduce DBPs formation, their high oxidation potential at low pH generated toxic N-DBPs. Mechanistic analysis indicated that the Fe(II)/S(IV) process was most effective in removing humic substances and biopolymers. Its moderate oxidation preserved macromolecular structures, enhancing coagulation. And the hydrolysis of S(IV) generates OH⁻, promoting electrostatic neutralization and floc enlargement. Cost analysis revealed that the Fe(II)/S(IV) process is significantly more economical, with costs only 1/60 of Fe(II)/PMS. These results highlight the Fe(II)/S(IV) process as a promising and cost-effective approach to advanced water treatment. © 2025 Elsevier B.V.

Insight into the Deterioration Mechanism of Gas Diffusion Electrode During Long-Term Electrosynthesis of Hydrogen Peroxide Under Industrially Relevant Current Densities

The long-term stability of gas diffusion electrodes (GDEs) is critical for industrial H2O2 electrosynthesis from two-electron oxygen reduction reaction (2e-ORR), but has rarely been investigated. Herein, we evaluated the stability of carbon black-polytetrafluoroethylene (CB-PTFE) based GDEs during H2O2 electrosynthesis in sodium sulfate (Na2SO4) electrolytes under industrially relevant conditions. Results show that the GDEs maintained stable H2O2 production with Faradaic efficiencies (FEs) of ~75% for ~300 h under 150 mA/cm2. However, FEs then declined gradually to eventually ~15% at 840 h, after which the GDE failed due to water flooding. Increasing applied current density to 200 mA/cm2 accelerated the deterioration process and caused electrode failure after 350 h operation. Characterizations of the GDEs used for varying durations indicate that the deterioration of GDEs is mainly caused by oxidation of CB catalysts, defluorination of PTFE, and intercalation of Na in CB particles during H2O2 electrosynthesis. These three interrelating mechanisms gradually decreased the hydrophobicity, the 2e-ORR activity and selectivity of GDEs, and increased the porosity of GDEs. These changes in turn promoted H2O2 decomposition and progressive water intrusion into the internal pores of GDEs during H2O2 electrosynthesis, thus causing the gradual decreases of FEs and electrode flooding. Due to the gradual changes of GDE properties, it is challenging to maintain long-term stable H2O2 production under industrially relevant current densities. More studies are needed to improve the design and operation of GDEs to resolve the deterioration process of GDEs and thus extend their lifetime during H2O2 electrosynthesis. © 2024, The Authors.

Periodate-based advanced oxidation processes: A review focusing on the overlooked role of high-valent iron and manganese species

引用

Chemosphere 2023年第1期337卷 139442页

Periodate-based advanced oxidation processes (AOPs) have received mounting attention in scientific research in the past two decades due to their fair oxidizing capability for satisfactory decontamination performance. Unlike iodyl (IO3•) and hydroxyl (•OH) radicals are widely recognized as the predominant species generated from periodate activation, the role of high-valent metal as a dominant reactive oxidant has been proposed recently. Although several excellent reviews concerning periodate-based AOPs have been reported, there are still prevalent knowledge roadblocks to high-valent metals' formation and reaction mechanisms. Therefore, this work aims to provide a comprehensive overview of high-valent metals, especially concerning the identification methods (e.g., direct and indirect strategies), formation mechanisms (e.g., formation pathways and interpretation based on density functional theory calculation), reaction mechanisms (e.g., nucleophilic attack, electron transfer, oxygen-atom transfer, electrophilic addition, and hydride and hydrogen-atom transfer), and reactivity performance (e.g., chemical properties, influencing factors, and practical applications). Furthermore, points for critical thinking and further prospects for high-valent metal-mediated oxidation processes are suggested, emphasizing the need for parallel efforts to enhance the stability and reproducibility of high-valent metal-mediated oxidation processes in real world applications. © 2023 Elsevier Ltd
