We report an unrecognized, tidal source of reactive oxygen species (ROS). Using a newly developed ROS-trapping gel film, we observed hot spots for ROS generation within ∼2.5 mm coastal surface soil. Kinetic analyses showed rapid production hydroxyl radicals (•OH), superoxide (O2•–), and hydrogen peroxide (H2O2) upon shift from high tide to low tide. The exhibited distinct rhythmic fluctuation. oscillations the redox potential dissolved concentration followed same pattern as •OH production,...
Reactive oxygen species (ROS) play key roles in driving biogeochemical processes. Recent studies have revealed nonphotochemical electron transfer from redox-active substances (e.g., iron minerals) to as a new route for ROS production. Yet, naturally occurring minerals mainly exist thermodynamically stable forms, restraining their potential Here, we report that tide-induced redox oscillations can activate enhanced •OH production intertidal soils (15.8 ± 0.5 μmol/m2) was found be 5.9-fold more...
This study describes a promising porous and efficient adsorbent, sulfonic acid (-SO<sub>3</sub>H) functionalized covalent organic framework (COF-SO<sub>3</sub>H), for the removal of pharmaceuticals personal care products (PPCPs) in water wastewater.
Photochemically generated reactive oxygen species (ROS) play numerous key roles in earth's surface biogeochemical processes and pollutant dynamics. ROS production has historically been linked to the photosensitization of natural organic matter. Here, we report photochemical from three naturally abundant iron minerals. All investigated minerals are photoactive toward sunlight irradiation, with photogenerated currents linearly correlated incident light intensity. Hydroxyl radicals (•OH)...
The hydroxyl radical (•OH) is a potent oxidant and key reactive species in mediating element cycles pollutant dynamics the natural environment. source of •OH historically linked to photochemical processes (e.g., photoactivation organic matter or iron minerals) redox chemical reaction microbe-excreted reduced iron/natural matter/sulfide-released electrons with O2 soils sediments). This study revealed ubiquitous production via water vapor condensation on mineral surfaces. Distinct productions...
Iron minerals are widespread in earth's surface water and soil. Recent studies have revealed that under sunlight irradiation, iron photoactive on producing reactive oxygen species (ROS), a group of key regulating elemental cycling, microbe inactivation, pollutant degradation. In nature, exhibit varying crystallinity different hydrogeological conditions. While is known parameter determining the overall activity minerals, impact mineral photochemical ROS production remains unknown. Here, we...
Hydroxyl radical (•OH) is a powerful oxidant abundantly found in nature and plays central role numerous environmental processes. On-site detection of •OH highly desirable for real-time assessments •OH-centered processes yet restrained by lack an analysis system suitable field applications. Here, we report the development flow-injection chemiluminescence (FIA-CL) continuous •OH. The based on reaction with phthalhydrazide to generate 5-hydroxy-2,3-dihydro-1,4-phthalazinedione, which emits (CL)...
Two imine-based covalent organic frameworks with different pore sizes were synthesized, and can be used as adsorbents for the removal of bisphenol pollutants, showing high affinity toward S A.
The demands for cost-effective solar fuels have triggered extensive research in artificial photosynthesis, yet the efforts designing high-performance particulate photocatalysts are largely impeded by inefficient charge separation. Because separation a photocatalyst is driven asymmetric interfacial energetics between its reduction and oxidation sites, enhancing this process nanoscale tuning of on prerequisite not impairing kinetics selectivity surface reactions. In study, we realize target...
Cadmium (Cd) contamination poses a significant global threat to human health, primarily through dietary intake, with rice serving as major source. While Cd predominantly resides in bound states soil, the physiological processes by which facilitates absorption rhizosphere remain largely elusive.
