Summary: Hydroxyl radicals (OH) play a crucial role as oxidants in atmospheric chemistry, and their aqueous sources have been mainly attributed to known bulk processes or interfacial chemistry driven by O3 and NO3 radicals. This study provides experimental evidence that OH radicals can be spontaneously produced at the air-water interface of aqueous droplets, even in the absence of known precursors, possibly due to the strong electric field formed at such interfaces. The measured OH production rates in atmospherically relevant droplets are comparable to or higher than those from known bulk sources, particularly in the dark. As aqueous droplets are widespread in the troposphere, this interfacial source of OH radicals is expected to have significant impacts on atmospheric multiphase oxidation chemistry, with implications for air quality, climate, and health.

Summary: This work focuses on synthesizing tailor-made catalysts based on the Co4O4 core for the catalytic aerobic cyclohexane oxidation reaction. The catalytic activity and selectivity of the catalysts are correlated with the electronic density of the cluster, modulated by changing the organic ligands. The results show that the catalyst with the highest oxidation potential promotes the formation of peroxide and superoxide species, providing insight into the mechanism of oxidizing inactivated CH bonds in alkanes.

Summary: Specific ligands can greatly enhance contaminant degradation during sediment oxygenation by increasing the utilization efficiency of sediment electrons. The electron utilization efficiency for (OH)-O-center dot production increases with higher ligand concentrations, and is mainly enhanced by changes in sediment surface Fe(II) coordination for low adsorption affinity ligands, and by electron transfer from sediment to dissolved Fe(III)-ligand for high adsorption affinity ligands.

Summary: The photo-irradiation of natural organic matter is a well-known pathway for the production of ·OH in surface waters. This study demonstrates that the presence of naturally occurring reduced species, sulfide, in environments containing natural organic matter contributes to ·OH production even under dark conditions. The concentration of sulfide has a more significant impact on ·OH production than the concentration of humic acid, and the interaction between sulfide and humic acid results in the formation of redox-active moieties responsible for ·OH production.

Summary: In this study, the concentrations of hydroxyl radical (OH) were observed using chemical ionization mass spectrometry in Hong Kong from October to November 2020. The study found that a model overpredicted the OH concentrations for coastal air parcels due to unaccounted-for OH sinks. The missing OH reactivity in coastal air was estimated to be 5.0 ±2.6 s(-1) (lower limit), and it increased with decreasing concentrations of nitrogen-oxide (NOx) and volatile organic compounds (VOCs).

Summary: This study investigated the photocatalytic transformation pathways of 5-fluorouracil (5-FU) and the inhibition mechanisms of its degradation efficiency reduction using TiO2 supported on nickel foam (TiO2/NF) as the photo-catalyst and pharmaceutical micropollutant. The produced intermediates during the photocatalytic degradation of 5-FU were identified as mono/polyhydroxylated compounds, short-chain oxides, and carboxylation ones. The inhibition of 5-FU degradation was found to be attributed to the competition for hydroxyl radical (center dot OH) and the preferential consumption of center dot OH in the TiO2 diffusion layer by the intermediates.

Summary: Nitrate (NO3-) and nitrite (NO2-) are common water pollutants and need to be controlled for water quality. A method using Pd-loaded TiO2 (Pd/TiO2) in an aqueous suspension has been developed for the conversion of nitrite to nitrate. The presence of aquatic pollutants such as arsenite (As (III)) or 4-chlorophenol (4-CP) can change the main photoconversion product from nitrate to N-2 and enhance the durability of Pd/TiO2. This process can be a viable treatment option for nitrite-contaminated water with various aquatic pollutants.

Summary: The first examples of phenanthroimidazole-based covalent organic frameworks (COFs), PIm-COF1 and PIm-COF2, were reported in this study, showing substantial optical properties. PIm-COF2 exhibited an average hydrogen evolution rate of 7417.5 μmolg-1h-1, which was 14 times higher than that of PIm-COF1 (528.5 μmolg-1h-1). This can be attributed to the strong donor-acceptor effect of PIm-COF2 and the continuous separation and transfer of the photoexcited electron-hole pair from the phenanthro[9,10-d]imidazole moiety, which was confirmed by time-dependent density functional theory and excitation state analysis.

Summary: As nations transition towards low or net zero carbon economies due to global climate change, the need for practical alternative fuels is urgent. Hydrogen gas is considered one of the most desirable substitutes for traditional hydrocarbons, but obtaining "green" hydrogen from low or zero carbon footprint sources presents challenges. Research focuses on practical techniques for producing "green" hydrogen through photocatalytic or photoelectrocatalytic processes. However, the capability of this technology to produce hydrogen at scale has faced significant issues. This road map article explores various aspects of photocatalytic and photoelectrocatalytic hydrogen generation, including processes, materials science, reactor engineering, and biomass reforming applications.

Summary: Researchers have developed a p-type NiO nanoplate thin film photocathode with rich Ni vacancies, which can harvest sunlight and store electrical energy in a single material. The band gap excitation of NiO creates surface adsorption of hydroxide anions and storage of photogenerated holes, forming NiOOH. The stored energy in NiOOH can be discharged to provide a sustainable current in the absence of light. The energy storage capacities of NiO depend on the electrolyte pH and the applied bias.

Summary: In this study, the molecular-level reaction mechanism of nanoporous gold electrodes for the conversion of carbon dioxide to carbon monoxide was investigated using surface-enhanced infrared absorption spectroscopy (SEIRAS). It was found that the nanoporous gold electrodes promoted the formation of linear CO intermediate and suppressed the formation of bridging CO intermediate. The study also revealed a high local pH and slow diffusion kinetics of local CO3 (2-) at specific reaction potentials. These findings provide insights into the electrochemical kinetics and mechanisms occurring in the electric double layers, highlighting the potential for designing efficient electrocatalysts for CO2 reduction.

This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
