Air pollution poses a widespread threat to human health, particularly due to its strong link to respiratory diseases. Airborne microbes, including bacteria, fungi, viruses, and cellular debris, are estimated to account for approximately 25% of atmospheric particulate matter (PM), some of which are pathogenic to humans. Researchers at The Hong Kong Polytechnic University have conducted a groundbreaking investigation into the sources, composition and health-related toxicity of these microbial particles, revealing concerning connections between air pollution and its impact on human health. 

We report a dual IEF-driven S-scheme heterojunction based on TpAQ and ZIS for photocatalytic H₂O₂ production. Without using any sacrificial agents or cocatalysts, TpAQ/ZIS-10 exhibits superior visible-light driven H₂O₂ production rate compared to unitary TpAQ and ZIS, illustrating the facilitated photogenerated charge separation and transfer by dual IEF-driven S-scheme heterojunctions. More importantly, the dual-pathway in TpAQ/ZIS-10 involving 2e⁻-ORR and 4e⁻-WOR synergistically promote photocatalytic H₂O₂ production during the reaction process.

As a crucial agricultural yield-increasing technique in arid and semi-arid regions, plastic film mulching (PFM) has significantly enhanced crop yield and quality by increasing soil temperature, reducing water evaporation, and optimizing nutrient cycling. However, with the increasingly prominent issue of farmland microplastic pollution caused by residual plastic films, this "white revolution" is now facing severe challenges to sustainable development.
