Summary: In this study, an eco-friendly and practical technology was developed to effectively stabilize and recover Cr(VI) in Chromite Ore Processing Residue (COPR) via a combination of FeSO4 reducing agent and hydrothermal treatment. The stable spinel phase product formed during detoxification facilitated the magnetic separation of ferrochrome resources. Under optimal hydrothermal conditions, the total Cr leaching concentration of treated COPR was significantly reduced, well below regulatory limits, making it a suitable raw material for the steel industry after magnetic separation. This work provides important insights for the harmless disposal and resource utilization of other chromium-containing hazardous wastes.

Summary: This study proposed a method of using hydrolyzed biomass as a reducing agent to achieve the harmless treatment of chromium ore processing residue. By a two-stage sulfuric acid leaching and biomass reduction of hexavalent chromium, as well as a one-step combined leaching and reduction process, the detoxification of the residue was successfully achieved. The suitable operating conditions for different stages were determined through orthogonal tests and single factor tests, including biomass hydrolysis, acid leaching, reduction, and combined leaching and reduction. The content of Cr(VI) in both the leach residue and reduction solution met the discharge criteria. FTIR and XPS measurements showed that the reducing sugars produced by the hydrolysis of biomass reacted with the leached Cr(VI) to generate chromium sulfate adsorbed on the surface of the residue. XRD and SEM-EDS results indicated that gypsum was generated after the detoxification, which can be utilized as a resource.

Summary: Ferrochrome (FeCr) is a crucial alloy for stainless steel production, primarily composed of iron (Fe) and chromium (Cr). FeCr is manufactured from chromite ore, which is the most important source of virgin Cr units. FeCr producers are paid based on the Cr content in the alloy, leading to the transportation of the Fe content without any economic benefit. This study investigated the selective removal of Fe from chromite ore to increase the Cr/Fe ratio. Although high Cr/Fe ratios were achieved, the recovery of Cr decreased significantly. The study also achieved desirable Cr/Fe ratios while maintaining high Cr recoveries.

Summary: Multiferroic Fe-site engineered lead iron niobate (PFN) is prepared by substituting Fe with Ni, Co, and Cr. The study investigates the effect of spin configuration variation on magnetic and multiferroic properties. Different transition metals result in distinct magnetic orders, and Ni and Co substitution leads to magnetic-field-dependent magnetoelectric coupling at room temperature. This research can provide a general method for modulating the magnetic properties of multiferroic perovskite oxides.

Summary: In this study, a Ru/RuO2-Co3O4 catalyst was developed to enhance the catalytic performance of acidic oxygen evolution reaction by constructing a heterointerface between RuO2 and Co3O4 and vacancy engineering. The resulting Ru/RuO2-Co3O4 catalyst showed a low overpotential and excellent stability, surpassing commercial RuO2. The favorable catalytic performance was attributed to interfacial charge transfer and the presence of oxygen vacancies. This research is expected to benefit the design and synthesis of more efficient electrocatalysts for energy-related devices.

Summary: A Cu-deficient CuxInSe2 phase was successfully synthesized as a thin film using a two-step process. The study found that the loss of Cu in the compound resulted in changes in the chemical states and local structure of the Cu-Se-In tetrahedral networks, with a shorter In-Se bond and excessive oxidation of In ions. Furthermore, the narrowing of the bandgap was attributed to the reconstruction of the In3+ & delta; 5s orbital states, making the material suitable for photovoltaics.

Summary: Progress in acidic water splitting has been limited by low oxygen evolution reaction (OER) activities, slow reaction kinetics, and catalyst degradation. In this study, t-phase ruthenium oxide atomic layers implanted on Mo2TiC2Tx MXene (RAL-M) were used as a model electrocatalyst for OER in acidic media, exhibiting remarkable mass activity and durability. Computational calculations reveal that RAL-M has strong affinity to oxygen species, enabling efficient water dissociation and accelerating the OER.
