作者： Gao, Ze Xu, Ming Liu, Renming Yang, Daming Yang, Yating Feng, Ming Wang, Ting School of Physics Changchun University of Science and Technology Changchun130022 China Key Laboratory of Functional Materials Physics and Chemistry of the Ministry of Education Jilin Normal University Changchun130103 China

Improving the activation and adsorption and of N2 by catalysts is crucial for developing efficient nitrogen reduction catalysts. Doping and defect engineering are important methods for addressing these issues. Doping a certain amount of Mo in CoS is beneficial for increasing the active positions, which heightens the attachment of N2. Due to the unique structure of the sulfur vacancy, it is advantageous to weaken the NN bond, thus enhancing the efficiency of electrocatalysis from N2 to NH3. Therefore, this work focuses on designing a Mo-doped CoS electrocatalyst with an abundance of sulfur vacancies to enhance its electrocatalytic performance in nitrogen reduction. The Vs-Mo/CoS-8% achieves an impressive NH3 yield of 38.19 μg h-1 mgcat-1 and Faraday efficiency of 23.99% at an electrical potential of -0.45 V (vs. RHE). Furthermore, it demonstrates long-term stability for up to 24 hours. This study not only broadens the diversity of available electrocatalysts but also provides new ideas for designing efficient and stable ones. © Published under licence by IOP Publishing Ltd.

Inorganic Additives Induce More Small-Sized Microplastics Releasing from Medical Face Masks

Although previous studies have extensively explored the release of microplastics from masks, the specific influence of inorganic additives on microplastic emissions has remained unidentified. Herein, we performed a comparative analysis of medical face masks (MFMs) with calcium carbonate (CaCO3) additives against those devoid of CaCO3 to understand their roles in microplastic release. Briefly, our investigation employed surface-enhanced Raman spectroscopy (SERS) to examine micro- and nanoplastic release, while the stereoscopic characterization of mixing states of additives in microplastic was accomplished through a simulated Raman scattering (SRS). We also pioneered a three-dimensional imaging (3D imaging) method for investigating the internal aging of plastic using SRS, which clearly revealed the link between inorganic additives inside polymers and photoaging. We found that inorganic additives substantially accelerate the photoaging of the plastic materials through multiple pathways and induce more small-sized microplastics. Follow-up radical quenching experiments confirmed carbonate radicals as the main cause of this phenomenon. Our research exposes the hazardous potential of inorganic additives in masks to amplify the emission of microplastics. © 2025 American Chemical Society.
