Summary: Atomically defined large metal clusters have significant applications in new reaction development and the synthesis of materials with tailored properties. In this study, a new class of Fe clusters, Tp*4W4Fe13S12, with M-M bonds is reported, which has only been observed in main group and late metal chemistry. The Fe-13 core of this cluster exhibits a large spin ground state of S=13 and can undergo significant rearrangements through small molecule activations involving the transfer of up to 12 electrons.

Summary: Single-atom catalysts have attracted increasing attention in heterogeneous catalysis due to their unique electronic properties, but may have limited advantages for reactions that require multiple atomic metallic states or metal-metal bond surface sites. Fully exposed cluster catalysts, as a cross-dimensional extension to the concept of single-atom catalysts, provide diverse surface sites and offer the advantage of maximized atom utilization efficiency. This outlook summarizes recent advances in the design and characterization of cluster catalysts, along with potential challenges.

Summary: This study reports a material with fully-exposed Pd cluster dispersed on nanodiamond-graphene, which exhibits excellent catalytic antibacterial properties. The fully-exposed Pd cluster nanozyme shows higher oxidase-like catalytic performance than Pd single-atom oxidase mimic, Pd nanoparticles oxidase mimic, and previously reported palladium-based oxidase mimics. The Pd cluster sites efficiently catalyze the decomposition of oxygen to generate reactive oxygen species, resulting in strong antibacterial properties.

Summary: Direct dehydrogenation of alkanes poses a significant challenge in activating C-H bonds at low temperatures. This study reports fully exposed Pd clusters on a hybrid nanodiamond-graphene support for efficient dehydrogenation of ethylbenzene to styrene, demonstrating superior catalytic performance and stability compared to previous catalysts. The synergetic interaction between adjacent Pd atoms in each cluster enables effective activation of C-H bonds on ethyl, leading to higher activity than typical Pd single atom and Pd nanoparticle catalysts.

Summary: Constructing highly active photocatalysts with rich reactive sites allows for the environmentally friendly utilization of CO2 with organic compounds. In this study, single-atom (SA) decorated two-dimensional (2D) single-layer ZnIn2S4 (ZIS) nanosheet composites with dual active centers of Co and Zn were used for CO2 fixation under visible light. The optimized Co-(s)ZIS composites exhibited significantly improved CO2-epoxide cycloaddition performance, attributing to the unique ensemble that optimizes light harvesting, promotes charge carrier separation, and enriches the bifunctional active sites. This work provides a paradigm for interfacial engineered SA-onto-2D semiconductors and highlights the structure-activity relationship by the well-defined active sites in this SA-based hybrid platform.

Summary: In alkaline wastewater with high arsenic concentration, traditional lime precipitation generates large amounts of hazardous waste. In this study, a heat-activated reduction method using thiourea dioxide (TDO) was proposed to efficiently remove and recover arsenic from alkaline wastewater. More than 99.9% of As(III)/As(V) were reduced to As(0) with a purity of more than 99.5 wt% by TDO within 30 min. The highly reductive eaq -and SO2• radicals generated during TDO decomposition significantly contributed to the arsenic reduction. Increasing pH and temperature improved the arsenic reduction by accelerating the formation of eaq -and SO2• radicals. Dissolved oxygen had a negative effect on arsenic removal, while CO32- slightly suppressed the removal effect. SiO32-, PO43-, Cl-, SO42-, and NH4+ had negligible effects. This method has potential for efficient arsenic removal and reduction in alkaline wastewater.

Summary: Efficient electrocatalysts with high mass activities for CO2 reduction can be prepared by transplanting Au active sites into a Ni4 nanocluster. The Au-transplanted nanocluster selectively produces CO with remarkable activity and stability. The contrasting selectivity is attributed to the CO blocking effect on Ni sites and the CO2-to-CO electroreduction activity of Au sites.

Summary: The novel synthesis of metal-phthalocyanine-based p-type semiconducting 2D c-MOF films with unprecedented edge-on layer orientation at the air/water interface was reported. The unique layer orientation allowed for investigation of lateral and vertical conductivities, revealing anisotropic charge transport properties. Directional conductivity studies identified that intrinsic conductivity is dominated by charge transfer along the interlayer pathway, demonstrating potential for various optoelectronic applications.
