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: 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: 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.

Electrochemical advanced oxidation processes (EAOPs) using reactive species for oxidation have shown promise for on-site treatment of water with organic contaminants. Recent progress in nanotechnology has led to research on efficient and durable electrocatalysts/electrodes for EAOPs. This review provides an overview of wastewater treatment using electrochemical technologies, particularly EAOPs, and evaluates the state-of-the-art electrocatalysts and their impacts on efficiency, stability, and selectivity.

Summary: This paper presents the use of synchrotron-based X-ray techniques to investigate the vanadium host phases in ancient marine sediments. The results show that vanadium is mainly present as vanadium (III) hosted by phyllosilicate. Strong associations between vanadium and potassium suggest that vanadium is hosted by potassium-rich clay minerals. Differentiating authigenic and detrital vanadium in ancient marine sediments is unlikely due to similar chemical speciation for both fractions.

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: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.
