Summary: This study focuses on the fractionation of lignin from corn stalk enzymatic hydrolysis to reduce heterogeneity and improve the microstructure and electrochemical performances of lignin-derived carbon materials. The results show that the fractionation process successfully obtained three lignin fractions with sequentially increasing molecular weight and specific surface area. Among them, the F3-derived carbon material (LC-F3) exhibits the highest specific surface area and the best heteroatom doping effect. Moreover, LC-F3 also shows excellent specific capacitance and cycling stability, which can be attributed to its high disordered level, heteroatom doping density, and specific surface area.

Summary: The rise in CO2 concentration in the Earth's atmosphere is the main cause of environmental issues such as global warming and ocean acidification. Electrochemical CO2 reduction (CO2RR) is a promising green approach to convert CO2 into valuable products. Heteroatom-doped porous carbon-based (HA-PCs) catalysts are considered ideal for CO2RR due to their favorable properties and ability to meet sustainability and large-scale requirements. This review focuses on the rational synthesis of HA-PCs and the impact of dopants on CO2RR activity and durability. It also discusses the effects of CO2 on the environment and human health, recent advances in CO2RR pathways and mechanisms, and the challenges and future perspectives of HA-PCs for CO2RR.

Summary: In this study, two-dimensional lignin-derived carbon nanosheets (N-LHPC) with hierarchically porous structures were synthesized through a novel metal-lignin assembly strategy. The N-LHPC showed excellent specific capacitance (235.75 F/g) and a maximum energy density (14.75 Wh/kg) due to its hierarchical pore structure and N/O functional groups. The metal-lignin assembly strategy, along with N-doping, improved the capacitance performances of the N-LHPC by providing hierarchical nanostructure, good electron/ion transfer properties, and abundant pseudocapacitive active species.

Summary: Tuning the reactive species in peroxymonosulfate (PMS) activation has been extensively studied in catalysis, but the photothermal effect on reactive species alteration has been neglected. In this study, a ZnFe2O4/C photocatalyst with oxygen vacancy was synthesized. The experimental results revealed that the photocatalytic activity of the catalyst without temperature control was higher than that under temperature control, and the primary reactive species were 1O2 and h+ without temperature control, while only 1O2 under temperature control. The possible activation site was speculated through in-situ Raman spectroscopy, XPS spectra, and cycling experiments. This research provides insight into enhancing the degradation rate of pollutants in photocatalysis by utilizing the photothermal effect on PMS activation.

Summary: In this study, a novel heterojunction of oxygen vacancy-rich TiO2-x confined in the layer space of a synthetic montmorillonite-like iron silicate (TiO2-x/FeMMT) was developed to address the issue of unsatisfactory electron transfer in photocatalysis-Fenton synergistic reaction. The two-dimensional layered montmorillonite-like silicates in the heterojunction provided more active sites for the reaction and induced oxygen vacancies in TiO2-x through interfacial effects, enhancing the visible-light harvesting ability. The TiO2-x/FeMMT composites exhibited superior photocatalysis-Fenton performance for the degradation removal of phenol, dinotefuran (DIN), and sulfamethoxazole (SMX) under visible-light irradiation.

Summary: This paper introduces the development and proof-of-concept testing of a trace analysis technique called F-SPE, which combines a fluorescent sensor with solid phase extraction (SPE) to simplify the procedure while maintaining low limits of detection (LOD). The technique involves concentrating an analyte onto a fluorophore-modified membrane and measuring its amount by quantifying the quenching of the fluorophore. The method was demonstrated by impregnating a SPE membrane with a perylene diimide (PDI) fluorophore for the low-level detection of organic amines and amine-containing drugs.

Summary: A sub-bituminous natural coal sample was modified with sulfuric acid and nitric acid to enhance its adsorption capacity for ciprofloxacin antibiotic residuals in water. The modifications resulted in increased surface area and the incorporation of new chemical groups into the coal structure. The adsorption capacities of the modified samples were significantly higher than the original sample, with the sulfuric acid modification showing the highest adsorption capacity. The adsorption of ciprofloxacin by the modified samples was mainly driven by physical forces, and the thermodynamic analysis indicated that the uptake of ciprofloxacin was spontaneous and endothermic.

Summary: Mo-modified (t-m)-ZrO2 photocatalysts were synthesized by a one-step hydrothermal method, which exhibited extended photoresponse in the visible light range and enhanced carrier separation efficiency due to the impurity band of Mo 4d states. The presence of MoO3 nanoparticles and doping Mo promoted the activation of H2O and CO2, and Mo modification facilitated the generation of *COOH intermediate and desorption of CO. The optimized Mo-modified ZrO2 showed a significantly higher CO yield and selectivity than bared ZrO2.

Summary: This study explores the influence of the morphological characteristics of hexagonal cadmium sulfide nanoparticles and nanorods on the photocatalytic performance of hydrogen production. It is found that the size difference between the nanoparticles and nanorods leads to different nanoconfinement effects, affecting the separation and migration kinetics of photoexcitons and thus the catalytic performance. By synthesizing CdS nanoparticles and nanorods and decorating them with single-atomic titanium, two forms of nano-confined systems are constructed. The results show that CdS nanoparticles, under the three-dimensional nanoconfinement dynamics, have a significant inhibitory effect on the migration of photoexcitons, resulting in higher photocatalytic hydrogen production under simulated sunlight conditions.

It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
