In this study, a heterogeneous microwave-responsive catalyst, RM/biochar (RM/BC), was successfully prepared to synergistically integrate magnetic and dielectric losses for activation of sodium percarbonate (SPC) to degrade the plastic additive diethyl phthalate (DEP). Characterization analyses revealed that under oxygen-limited conditions at 600 °C, poplar leaf powder was fully carbonized, while Fe₂O₃ in RM was reduced to FeO and further transformed into Fe₃O₄, forming a composite dominated by amorphous carbon and Fe₃O₄. In RM/BC-600, Fe₃O₄ and amorphous carbon collaboratively enabled dual hot-spot effects under microwave irradiation via magnetic and dielectric losses, accompanied by enriched oxygen vacancies. Hydroxyl radicals (•OH) were identified as the dominant reactive oxygen species (ROS) in SPC activation. Through single-factor and response surface optimization, under conditions of 40 μM DEP concentration, 4.03 mM SPC dosage, 6.24 g/L RM/BC-600 dosage, 87.2 °C reaction temperature, and 100 W microwave power, the optimal DEP removal efficiency reached 96.1 %. In-situ FTIR/Raman spectroscopy and EPR analysis demonstrated that RM/BC primarily facilitated SPC decomposition to hydrogen peroxide, with oxygen vacancies catalyzing hydrogen peroxide to generate •OH as the main ROS, supplemented by carbonate radicals (•CO₃⁻), superoxide radicals (•O₂⁻), and singlet oxygen (¹O₂), while dual hot-spot effects accelerated this process. HPLC-QTOF-MS identified 12 intermediate products, and plausible degradation pathways were proposed. ECOSAR software predicted reduced acute toxicity of degradation products, and seed germination assays confirmed minimal ecotoxicity of RM/BC to soil-plant systems. This study achieves RM resource recovery and hazard mitigation via a green strategy, enhancing plastic wastewater treatment through DEP detoxification and stability.</div></div>","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"700 ","pages":"Article 138506"},"PeriodicalIF":9.4,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144704065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigate the electrochemical reforming of glycerol in alkaline media to simultaneously produce hydrogen at a Pt cathode and formate at a NiSe₂ anode. The NiSe₂ electrode achieves a glycerol oxidation reaction (GOR) current density of up to 100 mA cm⁻² in a 1 M KOH solution containing 1 M glycerol, significantly outperforming a reference elemental Ni electrode. Both electrodes exhibit high Faradaic efficiencies (FE), achieving around 93 % for formate production at an applied potential of 1.6 V vs. RHE. To rationalize this exceptional performance, density functional theory (DFT) calculations were conducted, revealing that the incorporation of Se into NiSe₂ enhances the glycerol adsorption and modulates the electron density, thereby lowering the energy barrier for the initial dehydrogenation step in the formate formation pathway.

Under simulated solar irradiation, the CN/FTO heterojunction exhibits significantly improved photocatalytic H₂ production rate, reaching 607.7 μmol g⁻¹ h⁻¹, which is 9.5- and 7.1-fold higher than pure CN and FTO, respectively.

Diverse characterization techniques were applied to explore the structural, morphological, and compositional aspects of the material. To assess the energy storage potential of the NiO-CoS heterostructure electrode in lithium-ion and sodium-ion systems, electrochemical methods such as cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS) were systematically employed.
