Summary: Electrocatalysis is widely used for treating organic compounds in wastewater, but efficiently oxidizing gaseous organic compounds remains challenging. In this study, a Nafion-modified SnO2-Sb/Ti anode was fabricated and assembled into a solid-state reactor, achieving highly efficient electrooxidation of gaseous toluene. The Nafion-coated anode mineralized over 85% of toluene with >97% CO2 selectivity in 90 minutes at ambient temperature, compared to only 8% conversion over the bare anode under the same conditions. Nafion modification increased the electrochemical active surface area (ECSA), improved charge transfer, and enhanced surface hydrophobicity.

Summary: Prompted by the degraded forest in the area of the 2022 Chongli Winter Olympic Games, the Chinese government initiated a national program for mountain forest rehabilitation. This study developed a method to evaluate the quality of mountain forests using an index system consisting of stand structure, site conditions, and landscape aesthetics. The results showed that landscape aesthetics was the most important measure, while slope aspect and naturalness were the most and second-most important indices, respectively. The damaged forest was categorized into different types, and corresponding measures were proposed for their rehabilitation. The developed methods can be utilized for improving the quality of degraded forests in mountainous temperate areas.

Summary: This research evaluates recent trends in the research on the Irtysh River Basin, including its hydrological budget, water quality, biodiversity, and policy issues. The study finds that the melting of permafrost, glaciers, and snow is a key process affecting the hydrological budget, although the high evapotranspiration rate may offset the melting rate. Efficient operation of dams and reservoirs, as well as the restoration of tributaries, play important roles in restoring the ecological diversity of the basin.

Summary: This study analyzes the impact of economic and environmental indicators on carbon and greenhouse gas emissions in 29 OECD countries from 1990 to 2018. The findings suggest that export diversification has a negative effect on carbon emissions but promotes greenhouse gas emissions. Institutional quality, economic growth, financial development contribute to reducing carbon emissions but increasing greenhouse gas emissions. In contrast, trade openness has a positive influence on carbon emissions but a negative influence on greenhouse gas emissions. Additionally, urbanization is identified as one of the major factors contributing to environmental degradation.
