Co@Cu–MOF embedded alginate beads were manufactured in this study adopting a facile and environmentally friendly method, and they were utilized as a novel adsorbent to remove antibiotics from aqueous solutions. Alginate's inexpensive cost and biological compatibility as a natural support matrix were utilized in the manufacturing procedure in order to boost the MOF material's stability, flexibility, and recyclability. A series of characterization approaches, including x-ray diffraction patterns, Fourier transform infrared spectroscopy, scanning electron microscopy, and energy-dispersive x-ray spectroscopy analyses were used to describe the synthesized material's shape and elemental composition, indicating that the in situ synthesis of Co@Cu-based MOFs with alginic acid was achieved. Response surface methodology was used to comprehensively optimize the adsorption performance at pH (3–10), initial antibiotic concentration (10–100 mg/L), adsorbent dosage (0.02–0.35 g/L), and duration of contact (5–80 min) and validate the model. The Co@Cu–MOF/alginate beads demonstrated a high adsorption capacity of 95.75 mg/g and great affinity toward antibiotic molecules under the ideal conditions (pH 9, 45 min contact duration, and 0.17 g adsorbent dosage). Multilayered adsorption was confirmed by the equilibrium following the Freundlich isotherm and the kinetic data fitting well with the pseudo-second-order model.

Conventional control methods are often costly and ineffective, prompting the need for sustainable alternatives. One promising approach is biomass valorization in microbial fuel cells (MFCs), simultaneously addressing invasive species management and renewable energy generation. Beyond its recognized phytoremediation potential, water hyacinth can be effectively integrated into MFCs as a substrate, electrode material, membrane, and catalytic agent. Its lignocellulosic structure and carbonized derivatives offer high surface area and improved electron transfer, while natural fibers and root systems facilitate ion exchange and microbial colonization. These properties enhance MFC performance by boosting conductivity, biocompatibility, and cost-effectiveness relative to conventional materials. Reported WH-based MFC systems have achieved chemical oxygen demand (COD) removal efficiencies exceeding 65% and power densities up to 9.7 W/m<sup>3</sup>, demonstrating their dual potential for wastewater treatment and bioelectricity generation. Such multifunctional roles highlight WH as a valuable, low-cost resource for advancing MFC technologies. This review critically evaluates recent progress in WH utilization for MFC applications, focusing on biomass conversion, electrode and membrane development, and catalytic improvements.

The unique contribution lies in the integration of AI and machine learning models with FFA-based blending strategies to develop predictive frameworks for tailoring biodiesel blends to specific engine and climatic requirements. Strategic blending of biodiesels from feedstocks rich in specific FFAs enhances key physicochemical properties: saturated fatty acids such as palmitic (C16:0), stearic (C18:0), and lauric (C12:0) improve oxidative stability, flash point, and cetane number, while unsaturated fatty acids like oleic (C18:1) and linoleic (C18:2) reduce viscosity and enhance cold flow characteristics. AI/ML techniques, including SVM, ANN, XGBoost, CatBoost, and deep neural networks, enable high-precision prediction of FFA profiles and physicochemical properties such as cetane number, viscosity, density, cold flow behavior, and oxidative stability. In parallel, advanced production methods such as ultrasound-assisted transesterification, supercritical fluid processing, and nano-biocatalysts improve the biodiesel yield and physicochemical properties of the feedstock.

The emission characteristics of lean-burn gasoline engines differ significantly from those of conventional stoichiometric engines, and when close-coupled three-way catalysts (TWCs) are still applied, it is essential to understand their hydrothermal aging behavior. In this study, six Pd-only TWC samples with two Pd loadings (high and low) and three aging states (fresh, normally aged and lean-burn aged) were prepared. Their catalytic performance was evaluated on a flow reactor under steady-state lean-burn conditions, measuring NO, HC and CO conversion and NH<sub>3</sub> yield. Structural characterizations were carried out using XRD, BET, SEM and XPS. The results show that lean-burn aging causes more severe structural degradation and stronger depletion/oxidation of surface Pd species than normal aging, leading to pronounced deterioration of low-temperature (<300°C) NO and CO conversion. High Pd loading provides higher initial activity and superior high-temperature (>400°C) conversion, but suffers poorer low-temperature stability, whereas low Pd loading exhibits better structural stability and improved low-temperature HC conversion. Although both aging protocols reduce NH<sub>3</sub> yield, lean-burn aged catalysts show a smaller decrease and even relatively higher NH<sub>3</sub> yield at 300–350°C due to stronger CO oxidation deactivation and the resulting increase in residual CO. These findings provide guidance for optimizing Pd-based TWCs for lean-burn gasoline engines, especially when used upstream of PSCR.</p>","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 2","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147665923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By integrating ultraviolet–visible spectrophotometry with carbonaceous component analysis, the mechanism through which organic carbon (OC) components influence the light absorption behavior of biodiesel-derived PM was investigated. Results show that PM from diesel combustion exhibits significantly higher light absorption intensity than that from biodiesel combustion, with the light absorption capacity of biodiesel-derived particles increasing as fuel iodine value rises. OC2 dominates OC in diesel-derived particles, whereas OC in biodiesel-derived particles is composed of OC2, OC3, and OC4, among which OC3 has the highest proportion. Furthermore, the mass absorption cross-section (MAC) of elemental carbon (EC) is greater in biodiesel combustion particles than in diesel combustion particles, and the magnitude of light absorption enhancement correlates positively with increasing OC/EC ratios.

The analysis reveals significant regional heterogeneity in waste composition and management capabilities, necessitating context-specific solutions. The comparative assessment of resource recovery methods—including anaerobic digestion, composting, thermal conversion, and material transformation—demonstrates that despite the existence of technical solutions, their implementation faces significant barriers, including economic viability, technical expertise, and policy coordination.
