Summary: Phenolation is an efficient method to improve the reactivity of lignin. In this study, cellulolytic enzyme lignin (CEL) and kraft lignin (KL) of Simao pine were phenolated and characterized. The phenolated lignins were used to prepare size-controlled lignin nanoparticles (LNPs), with different sizes and surface charges depending on the degree of phenolation. The study provides new insights into the design, preparation, and application of LNPs.

Summary: This study developed a strategy to produce cellulose nanofibril (CNF) composite films using lignin nanoparticles (LNPs) as a reinforcing agent. The results showed that LNPs with higher phenolic hydroxyl (Ph-OH) content greatly improved the mechanical properties and UV-blocking ability of the composite films.

Summary: This study investigated the role of activated carbon properties in the adsorption of effluent organic matter (EfOM) from bio-treated coking wastewater. Commercial powdered activated carbons (PACs) with different pore structures, surface functional groups, and surface charges were used. The results showed that the adsorption of EfOM depended on its molecular size, with biopolymers being adsorbed by macropores and humics being adsorbed by mesopores. PACs with higher mesopore volume, fewer acidic groups, and higher isoelectric point were found to be more effective in removing EfOM.

Summary: Understanding the structure-activity relationship between adsorption performance and accessible adsorption sites is crucial for efficient adsorbent development in Ge(IV) recovery. In this study, three chitosan-based adsorbents were designed and investigated for their phenolic hydroxyl-induced steric effect on Ge(IV) recovery. The results showed successful grafting of phenolic acids onto the chitosan surface, and the adsorption behavior followed pseudo-second-order kinetics and Langmuir isotherm models. The Ge(IV) recovery performance correlated with the arrangement of active adsorption sites, with TBA-CS exhibiting the highest affinity. TBA-CS also demonstrated superior selectivity and maintained high adsorption efficiency after regeneration cycles, making it a promising adsorbent for Ge(IV) recovery.

Summary: The study found that hydroxyl radicals in H-BiOCl have a reverse inhibitory effect on the ring-opening reaction in the photocatalytic mineralization process of toluene, while C-BiOCl shows superior ability and stability in mineralizing toluene. This is because C-BiOCl lacking hydroxyl groups can selectively generate benzoic acid by holes and superoxide anion radicals; whereas H-BiOCl with a large number of hydroxyl groups will lead to the production of hydroxyl radicals and phenolic intermediates, reducing the performance and stability of the catalyst.

Summary: Soil zinc contamination poses a significant threat to water quality and sensitive ecosystems. Changes in soil redox conditions can lead to mobilization of zinc from common hosts, resulting in increased dissolved zinc concentrations in surface and groundwater. The oxygenation of contaminated riparian soil during low water conditions caused a spike in porewater zinc concentrations. As aridification intensifies, oxygenation of floodplain soils in mountain watersheds may lead to increased mobilization of dissolved zinc, amplifying the threat to water quality and ecosystem health.

Summary: This study investigated the formation mechanisms of silver nanoparticles (AgNPs) when Ag+ coexists with biomasses (BMs) and biochars (BCs). Different types of BMs and BCs were found to play different roles in transforming Ag+ to AgNPs, with temperature and pH having significant impact on the process. The results illustrate the importance of hydroxyl (-OH) groups in BMs and BCs for the reduction of Ag+ and the subsequent formation of AgNPs in the environment.

Summary: This review discusses technologies to remove hydrogen sulphide (H2S) during anaerobic digestion (AD). Post-treatment technologies have high removal efficiency but do not mitigate H2S toxicity. Input control reduces sulphur input but has lower removal efficiency. Microaeration for regulating the redox potential is a promising alternative with high removal efficiency and low operational cost.

Summary: Coconut shell biochars prepared from oxygen-free pyrolysis were used in a permeable reactive barrier (PRB) for electrokinetic remediation (EK) to remove 2,4,6-trichlorophenol (2,4,6-TCP) from soil. The addition of biochar to the PRB significantly increased the removal of 2,4,6-TCP compared to PRB without biochar. The voltage input was found to be the major factor influencing the TCP removal during the EK-PRB process. The optimal conditions for TCP removal were found to be 2 V cm-1 voltage, 700 degrees C pyrolysis temperature, and 40 mg L-1 initial TCP concentration. The biochar played multiple roles in EK remediation, including enhancing electroosmotic flow, adsorbing TCP, and promoting electrochemical degradation. Biochar from high pyrolysis temperature was particularly effective in enhancing electroosmotic flow and pollutant adsorption.

Summary: This study focuses on the influence of TiO2 surface chemistries on properties of formed vanadium species during a thermal activation. The results show that TiO2 with more Ti4+ tends to be reductive, while TiO2 with more Ti3+ tends to be oxidative. In the catalytic oxidization of chlorobenzene, the Ti4+-induced catalyst shows a much higher conversion rate compared to the Ti3+-induced catalyst.

Summary: The mobility of biochar in saturated quartz sand under a direct current (DC) electric field was investigated. It was found that the DC electric field significantly promoted the migration of biochar, with the recovery rate of particles being improved by 0.5-6.1 folds under 0.5 V cm(-1). Higher voltage potential, solution pH, and ionic strength were more favorable for biochar migration. The transport of biochar could be well explained by a deterministic nonequilibrium convection-dispersion equation model.

Summary: This study demonstrates the synergistic effect between alkaline-thermal treatment and zero-valent iron immobilized in biochar (BC-ZVI) for the enhanced degradation of perfluorooctanoic acid (PFOA). The use of 19F-NMR and density functional theory (DFT) analysis provided insights into the defluorination efficiency and degradation mechanisms. The results showed that alkaline strength played a primary role in the defluorination process, and BC-ZVI improved the reaction kinetics by 2.4 times. The combination of alkaline-thermal treatment and BC-ZVI resulted in near-complete removal of fluorinated compounds within a short reaction time.

Summary: In this study, the catalytic turnover frequencies (TOF) of Cu loaded ZSM-5, Beta, MOR, and SSZ-13 were determined, and the topology-localized Cu species in these zeolites were analyzed. Multiple Linear Regression was used to distinguish the TOF contributions of the Cu species, and density functional theory calculated NH3 dehydrogenation energy. The results showed that topologies with more node atoms exhibited higher TOF and lower dehydrogenation energy, and the best topology varied for each zeolite.

Summary: This study synthesized a series of biochar-like hyper-crosslinked polymers (HCPs) with different amounts of phenolic hydroxyl groups to investigate the roles of key surface properties of biochar in transforming pollutants. The results showed that increasing amounts of hydroxyl groups on HCPs led to higher production of hydroxyl radicals. Batch degradation experiments indicated that HCPs with the lowest amounts of hydroxyl groups showed the highest degree of trichlorophenols (TCPs) degradation, while HCPs with the highest hydroxyl group abundance exhibited the lowest degree of TCP degradation.
