Summary: The introduction of oxygen vacancies (Ov) has been proven efficient in enhancing the photoelectrochemical (PEC) water splitting performance. In this study, BiVO4 (BVO) photoanodes with both bulk and surface Ov were fabricated and their roles in PEC performance were investigated. The bulk Ov increased carrier density and improved electron-hole separation efficiency, while the surface Ov provided abundant active sites for charge injection. The synergistic effect between the bulk and surface Ov resulted in highly promoted PEC water splitting activity, offering a promising strategy for efficient solar water splitting systems.

Summary: This study introduces a novel Type II heterojunction consisting of BiVO4 thin film and diamond-like carbon (DLC) to the PEC system, which significantly enhances the PEC water-splitting activity. Compared to the pure BiVO4, the BiVO4/DLC heterojunction exhibits increased photocurrent density and improved stability. The enhancement in PEC performance is attributed to the Type II heterojunction photoanodes that promote carrier mobility and reduce the recombination rate of electron-hole pairs. Furthermore, the sp2 carbon phase in DLC acts as a conductive channel, while the sp3 carbon phase provides stable support and passivation effect, leading to an enhancement in both PEC water splitting performance and long-time stability.

Summary: This study investigated the adsorption activity and mechanism of four common types of tourmalines (magnesium-based and iron-based) for cationic and anionic dyes in aqueous solution. The tourmalines displayed electrostatic adsorption for cationic dyes, but very slight adsorption activity for the anionic dye. The large cationic group of one of the dyes hindered its absorption into the tourmaline structure, resulting in weaker absorption activity compared to another dye. Thermal treatment at 350 degrees C effectively desorbed the absorbed cationic dye on select tourmalines.

Summary: Inorganic mineral particles in the Sichuan Basin play a crucial role in the formation of atmospheric aerosols. The phase transition of mineral particles under high humidity and stable climatic conditions is closely related to atmospheric haze formation. This study employed backward trajectory analysis to trace the migration trajectory of mineral particles and used Positive matrix factorization (PMF) to identify the sources of atmospheric mineral particles. The phase transition mechanisms of these particles were investigated using various analytical techniques. The results revealed the presence of different migration and phase transition paths for the mineral particles, and identified sources included combustion, vehicle emissions, industrial emissions, agricultural sources, and mineral dust. The study highlighted the negative impact of mineral particle phase transition on aerosol formation and haze exacerbation. It also demonstrated how the interaction between specific mineral phases and anthropogenic volatile organic compounds (VOCs) significantly contribute to haze formation. Overall, this study provides valuable insights into the mechanism of aerosol formation in basin climates.

Summary: Inspired by electronic modification engineering, boron-doped SnO2 nanospheres are synthesized to enhance the efficiency of CO2 reduction reaction. The introduction of boron dopants increases the number of active sites and facilitates the formation of electron-rich Sn sites, resulting in enhanced CO2 activation and reduced energy barrier. The B-doped SnO2 electrocatalyst exhibits a remarkable FEHCOOH value above 90% within a broad potential window and achieves a maximum value of 95.1% at -1 V vs RHE, indicating its high performance in CO2RR. This work provides a novel strategy for optimizing the intrinsic properties of electrocatalysts for CO2RR by tuning the electronic structure.

Summary: From the Arrhenius and Eyring equations, it is understood that the temperature of an electrolyte plays a crucial role in the performance of electrocatalysts during water electrolysis, which is often overlooked in fundamental research. This study investigated the activity, kinetics, and stability of several electrocatalysts (Co3O4, NiFe alloy, NiFe LDH, and Pt) for oxygen and hydrogen evolution reactions in KOH electrolyte at different temperatures (20 to 80 degrees C). The electrocatalysts exhibited better water electrolysis activity and kinetics in higher-temperature electrolytes, attributed to enhanced conductivity, increased hydrophilicity, more active site formation, and reduced electrolysis resistance. However, they displayed weaker reaction stability, primarily due to increased dissolution during water electrolysis in high-temperature KOH electrolyte.
