Summary: Dissolved organic matter has dual roles in affecting the sorption properties of biochar for organic contaminants. On one hand, it inhibits the adsorption of contaminants by competing for sites and/or blocking pores. On the other hand, it promotes the partitioning of contaminants by serving as an additional partitioning phase. A modified dual-mode model that includes the concentration of dissolved organic matter can predict the effect on sorption properties.

Summary: This study investigated the interaction between biochar dissolved organic matter (BDOM) and 2,4,6-trichlorophenol (TCP) using fluorescence spectroscopy and multiple models. The results showed that protein- and fulvic-like components were the major interacting materials with TCP in BDOM. The static quenching mechanism dominated the interaction between BDOM and TCP, and the binding order of fluorescent components followed the sequence of protein-like -> short-wavelength fulvic-like -> long-wavelength fulvic-like -> humic-like components. These findings provide insights for selecting biochar as a remediation material for chlorophenols and understanding the environmental behavior of leached dissolved organic matter during biochar application.

Summary: This study investigates the roles of DOM derived from different biochar in biochar/PS systems and evaluates their environmental risk. The pore-clogging effect of DOM suppresses the adsorption capacity and catalytic performance of biochar, and the removal of DOM decreases the environmental risk of these systems. In addition, the leaked and accumulated DOM is toxic to Chlorella sp., with DOM from sludge-derived biochar showing the highest toxicity.

Summary: Biochar has been widely studied for its potential benefits as a soil conditioner and bio-accumulator, but its application in agriculture may pose risks to ecosystems due to the presence of toxic organic pollutants. The European Biochar Certificate sets production criteria, but even meeting these values may not prevent biochar from causing phytotoxicity. The presence of water-soluble organic compounds in biochar may be responsible for its phytotoxic effects.

Summary: Recently, biochar has been found to degrade the common organic environmental pollutant p-nitrophenol (PNP). However, the role of biochar-derived dissolved organic matter (BDOM) in PNP degradation remains unclear. In this study, two BDOM samples were prepared and their PNP degradation performance was analyzed. The study found that BDOM5 (prepared at 500 degrees C) showed a higher PNP degradation ratio compared to BDOM7 (prepared at 700 degrees C), and both oxidative and reductive processes contributed to the PNP degradation by BDOM. The higher PNP removal of BDOM5 was attributed to its higher electron exchange capacity, and hydroxyl radicals (•OH) played a critical role in the oxidative degradation process of PNP by BDOM. These findings may contribute to a better understanding of PNP degradation by BDOM and the environmental impact of biochar application.

Summary: This study evaluated the quantitative and qualitative characteristics of dissolved organic matter (DOM) derived from modified biochar. The results showed that the yield of DOM from modified biochar was reduced compared to original biochar, and the properties and environmental impact of biochar-derived DOM varied depending on the modification method and biochar type.

Summary: This study compared the effects of ordinary biochar and modified biochar on soil phosphorus and investigated the mechanisms of phosphorus mobility and immobilization. The results showed that the modified biochar reduced soluble phosphorus and transformed it into immobilized phosphorus, while the ordinary biochar promoted the transformation of phosphorus into soluble calcium phosphate. Additionally, abiotic processes played an important role in phosphorus transformation and sorption.

Summary: This study investigates the interaction between biochar-derived dissolved organic matter (DOM) and metal pollutant Pb(II) during adsorption. The results show that DOM significantly enhances the adsorption efficiency of Pb(II). Various testing methods reveal a static quenching mechanism between DOM and Pb(II), which has significant implications for environmental science and other fields.

Summary: BDOM released from biochar plays a crucial role in controlling pollutant interactions, increasing mobility of pollutants in aquatic environments, and affecting soil organic matter behavior. Further research is needed to understand the specific mechanisms involved in order to improve the efficiency of environmental pollutant remediation using biochar.

Summary: Amendment of soil with biochar alters microbial community structure and enhances mineralization of soil organic carbon. The addition of biochar leads to a decrease in persistent DOM components and an increase in labile DOM components in the soil. Additionally, biochar promotes the release of CO2 carbon from the soil.

Summary: Solid Oxide Fuel Cells (SOFC) with La0.3Sr0.7TiO3 (LST)-yttria-stabilized ZrO2 (YSZ) anodes were prepared and modified with Ni, Pt, Pd, Fe, Co, and CeO2, with even small loadings of Pt, Ni, and Pd significantly decreasing anode impedances for operation in humidified H-2 at 973 K. The effects of CeO2, Co, and Fe were also observed, with sintering at higher temperatures being important for performance improvement. Ways of stabilizing metal particles and implications for developing ceramic anodes were also discussed.

Summary: FeOx, SF, and BSF were studied as fuel oxidation catalysts in solid oxide fuel cell anodes. The addition of SF and BSF greatly reduced the impedance of the electrodes, while SrO or FeOx had a smaller effect. Stabilization of Fe+4 in the perovskite lattice was found to enhance the catalytic activity of SF and BSF by providing access to a Fe3+/Fe4+ redox couple.
