Summary: The localization and incomplete filling of 4f electrons enable cerium to have great potential in electrocatalysis and photocatalysis. The unique 5d empty orbital of cerium can act as a hydrogen trap site, facilitating hydrogen recombination and promoting hydrogen molecule desorption in electrocatalysis. Additionally, cerium-based nanomaterials have stable crystal structures, excellent oxygen mobility, and good optical properties, making them highly desirable for photocatalytic applications. This review summarizes the preparation methods of cerium-based nanomaterials and discusses their applications in electrocatalysis and photocatalysis, providing a promising prospect for their use in these fields.

Summary: Recent reports highlight the potential of technologies generating hydrated electrons for the destruction of per- and polyfluoroalkyl substances. This study examines the kinetics and mechanisms of these technologies when reacting with ultra-short chain fluorocarboxylates. The results demonstrate a wide range of rate constants and suggest that the reduction of fluorocarboxylates by hydrated electrons occurs through divergent mechanisms.

Summary: The use of Al beverage can powder as a substitute for zero-valent Al to conduct the Fenton-like reaction for Tl(I) oxidation and subsequent precipitation of Tl(III) at pH 9.5 was effective for Tl remediation. While the addition of Fe(III) or Fe(II) facilitated Tl(I) oxidation, it also reduced the overall Tl removal efficiency, highlighting the importance of considering the trade-off between oxidation and removal. This study demonstrated the comparable Tl(I) removal efficiency of AlCP to state-of-the-art (nano)composites, offering a unique opportunity for balancing hazard remediation and waste reduction/reuse considerations.

Summary: The mobilisation and speciation of arsenic in polluted gold mine sites in tropical climates are not well understood. This study investigated the impact of soil redox potential on the mobilisation of arsenic and its dominant species in an abandoned spoil. The results showed that arsenic mobilisation increased under moderately reducing conditions and decreased under oxic conditions. The dominant species of arsenic varied with redox conditions, with As(V) dominating under oxic conditions and As(III) predominating under moderately reducing conditions.

Summary: This study investigated the interference of ubiquitous substances on the co-removal of hexavalent chromium and arsenite. The results showed that the addition of Fe(II) promoted the reduction of Cr(VI) and suppressed the oxidation of As(III). Neutralizing the solution to pH 6.0 allowed for the complete removal of reduced Cr through Fe(II)-assisted adsorption and/or co-precipitation, while the removal of aqueous As was less effective. Fe(III) triggered high adsorptive and/or co-precipitative removals of both Cr and As. Organically-altered systems exhibited a decrease in As(III) oxidation, with oxalic acid competing with As(III) in redox interactions and DOC reducing As(V) into As(III). DOC also affected the precipitation of Cr and As through complexation and/or blocking adsorption or co-precipitation sites. This study unraveled the interference from ubiquitous species in the co-removal of Cr(VI) and As(III), providing insights for heavy metal contaminant remediation.

Summary: The transformation, transport, and release of phosphorus are influenced by anthropogenic activities and complex biochemical interactions. This study used X-ray absorption near edge structure spectroscopy to analyze the molecular P species in colloids, canal sludge, and coastal sediments collected from an area receiving effluents from agricultural and municipal activities. The study found that Fe(III)-bonded P dominated the P inventory, but its proportion was lower in colloids compared to sludge, indicating the contribution of other P species such as Al-P, Fe(II)-P, and org-P to colloidal P. The results highlight the importance of Fe(II) and Al in partitioning colloidal and sedimentary P and the role of organic matter degradation in P dynamics.

Summary: Thermoacidophilic Cyanidiales have a competitive advantage in extreme metal-rich environments. Cyanidioschyzon merolae (Cm), Cyanidium caldarium (Cc), and Galdieria partita (Gp) were found to effectively remove hexavalent chromium [Cr(VI)]. Cm and Gp could remove 168.1 and 93.7 mg g-1 of Cr(VI) at pH 2.0 and 7.0, with a significant portion being reduced to trivalent chromium [Cr(III)]. The presence of Cr(OH)3 was observed and correlated with the high sorption capacity of Cm and Cc at pH 2.0. These findings suggest that Cyanidiales have potential for environmentally-friendly and sustainable remediation of Cr(VI).

Summary: The accumulation of allelochemicals released by plants is a common occurrence in continuous monocropping systems. This study investigated the adsorption capabilities of biochar samples prepared from different agricultural residuals. The biochar prepared from wood meal exhibited the highest adsorption capacity, attributed to its high surface area and the presence of oxygen-containing groups. In a pot experiment, the addition of biochar promoted celery growth and reduced water-soluble phenolic compounds in the soil. However, the biochar also removed nitrate.
