Summary: The rational design of Fe3O4@MXene quantum dots (Fe3O4@MQDs) hybrid material with enhanced peroxidase-like activity is achieved through a facile ultrasonic strategy. The catalytic mechanism reveals that Fe3O4@MQDs can effectively decompose H2O2 to produce reactive hydroxyl radicals (center dot OH), which derives from the active sites of interfacial Fe-Ti dimer. A sensitive colorimetric sensor is proposed to detect Cr (VI) with a low detection limit of 0.26 μM, demonstrating the great potential of MQDs-based peroxidase-like enzymes in the detection of environmental pollutants.

Summary: A novel gold and copper bimetallic nanocluster-doped chitosan fluorescent composite film was successfully prepared by synthesizing gold and copper bimetallic nanoclusters emitting strong red fluorescence and utilizing a solution casting method. The composite film showed stable optical properties and could be stored for a long time. It exhibited strong and bright red fluorescence, making it suitable for real-time detection of Cr(vi), with a low detection limit (0.26 ppb) and satisfactory results in actual water samples. Its portability, high selectivity, and sensitivity also enable its extension to chemical and food detection.

Summary: The production of heavy-metal pollutants in industrialized systems poses threats to the environment and human health, especially the release of toxic and potentially carcinogenic Cr(VI) wastewater. However, few efficient colorimetric methods were available for Cr(VI) detection. To address this issue, a Cu bimetal-organic framework (Cu-MOF) was utilized to construct a visual colorimetric sensor for Cr(VI) detection. This method allows for the rapid detection of Cr(VI) with a wide linear range and excellent selectivity against interfering ions and anions commonly found in wastewater. With its fast response time and potential for on-site screening and point-of-care testing, the Cu-MOF sensor represents a promising development in Cr(VI) detection.

Summary: The intrinsic magnetic order in single-layer chromium trihalides has potential applications in spintronic devices, but their environmental instability poses challenges for practical use. By investigating the degradation chemistry of chromium iodide, researchers found that it undergoes hydrolysis and surface oxidation reactions under different environments, leading to its rapid degradation. However, using organic acid solvents as reversible capping agents can effectively stabilize CrI3 nanoflakes for more than a month.

Summary: Heterogeneous single-atom spin catalysts combined with magnetic fields have been designed for accelerated chemical reactions. A hydrothermal approach was used to synthesize single-atom spin catalysts with various substitutional magnetic atoms in a MoS2 host. The Ni-1/MoS2 catalyst with a distorted tetragonal structure showed global room-temperature ferromagnetism, and the addition of a mild magnetic field significantly enhanced the oxygen evolution reaction magnetocurrent, leading to excellent activity and stability in water splitting cells.
