Summary: This study demonstrates the microwave-assisted fabrication of pristine CuO and Cd/Zn co-doped CuO nanopowders and evaluates their structure, chemical nature, shape, and optical response. The co-doping of Cd and Zn substantially reduces the energy gap of CuO and inhibits e-/h+ recombination, enhancing the photocatalytic activity. Cu0.94Cd0.03Zn0.03O nanosheets exhibit the highest mineralization efficiency for Congo-red pollutants under sunlight irradiations, making them a promising option for the treatment of organic pollutants in industrial effluents.

Summary: In this study, FeS micro-flakes were successfully synthesized and showed good stability and dispersibility in water, leading to high efficiency in removing Hg(II). The sorption of Hg(II) on FeS micro-flakes was consistent with the pseudo-second-order kinetic model and Langmuir model, indicating monolayer sorption dominated by chemical sorption. The maximum sorption capacity was significantly higher than FeS nanoparticles and other Hg(II) scavengers. FeS (0.31 g/L) effectively removed >97.6% of 200 mg/L Hg(II) in the pH range of 2-12 at 30 degrees C. The removal mechanism involves chemical precipitation and surface adsorption. This study demonstrates the potential and viability of FeS micro-flakes for efficiently removing aqueous Hg(II).

Summary: The coordination of oxygen atoms induces the reconstruction of catalytic sites, which is crucial for understanding the mechanism in dynamic catalytic processes. We demonstrated that the reconstructed catalytic sites on Co (CoP) surface showed improved activity and selectivity for photocatalytic CO2 reduction. In-situ Raman spectroscopy revealed the formation of reconstructive Co-O bond and the appearance of intermediate CO, providing insights into the relationship between catalytic site structure and photocatalytic properties. Density functional theory calculations further showed that the electronic structure of reconstructive surface sites enhanced the ability of CO2 adsorption and CO desorption, leading to reduced barrier energy for the rate-determining step and improved CO2 reduction performance.

Summary: A Fe-N-C electrocatalyst with dense FeN4 sites on hierarchically porous carbons with highly curved surfaces (FeN4-hcC) is reported, which displays exceptional ORR activity in acidic media. When integrated into a membrane electrode assembly, the corresponding cathode shows a high maximum peak power density and operating durability over 30,000 cycles, outperforming previously reported Fe-N-C electrocatalysts. This work provides new insight into the carbon nanostructure-activity correlation for ORR catalysis and offers a new approach to designing advanced single-metal-site catalysts for energy-conversion applications.

Summary: Exploring the interactions among doping heteroatom, carbon and metal atoms can significantly enhance the catalytic performance and gain an insightful understanding of the heterogeneous catalysis mechanism. The N,P co-doped carbon-coated cobalt (Co@NPC) catalyst exhibits high selectivity and water-durability in aqueous-phase hydrogenation of cinnamaldehyde, with precise control of products by adjusting N and P doping. The synergy of geometry and electrons in Co@NPC di-heteroatoms allows for selective reduction of C=O, while Co@NC without P doping shows high activity but significant productivity of saturated alcohols under equivalent conditions. The electronegativity difference among N, C and P atoms enables interaction between electrons, adjusting the chemical states of the active metal and enhancing catalytic performance in hydrogenation.

Summary: In this study, a metal-free carbon catalyst NDPC-1000 with a graphitic N-regulating defect structure was designed for anion-exchange membrane fuel cells (AEMFCs) through theoretical calculations and experiments. The graphitic N was found to tailor the charge density of defects to enhance the adsorption energy-activity relation, and the high durability was attributed to the dissociation energy of the C-N covalent bond. The synthesized NDPC-1000 demonstrated excellent ORR activity and durability in alkaline media, achieving a peak power density of 913 mW cm(-2) and a voltage decay of approximately 25% after 100 hours of continuous operation.

Summary: The ability to monitor ammonium/ammonia levels in coastal waters in real-time and continuously is crucial for assessing the impact of eutrophication on ecosystems. In this study, a membrane-based conductometric ammonia sensing probe (CASP) was used to monitor ammonia levels in coastal waters. The use of a boric acid/glycerol receiving phase helped overcome the analytical errors caused by high salinity. The findings showed that CASP can accurately monitor the dynamic changes in ammonia concentration in coastal waters over an extended period of time.

Summary: The development of dimensionally stable anodes (DSAs) has made the chlorine evolution reaction (CER) the most important industrial anode reaction since the 1960s. However, the preparation of DSA relies on the use of expensive and scarce precious metals. In this study, a cationic defect adsorption-oxidation anchoring strategy is employed to immobilize oxidized sub-nano ruthenium clusters on a 2D low-crystallinity titanium oxide (2D TiOx) substrate, leading to enhanced activity, selectivity, and stability for CER.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
