Article Abstract
An AuCu bimetallic nanourchin electrocatalyst, rich in low-coordinated Au/Cu atoms, achieves an impressive ∼100% faradaic efficiency (FE) for reduction of CO to multicarbon (C) products, including 63.8% acetate and 36.2% ethanol at an ultralow potential of -0.4 V RHE. This work establishes a novel paradigm for the precise nanostructure engineering of AuCu bimetallic electrocatalysts toward efficient synthesis of high-value C products.

Carcinoembryonic antigen (CEA) is a clinically significant biomarker for early-stage cancer diagnosis and therapeutic monitoring. Conventional immunoassays, while effective, suffer from limitations in stability, sensitivity, and procedural complexity. In this work, we report a label-free nanozyme electrochemical biosensor (nanoE-EB) integrating self-assembled peptide-templated Au/Cu bimetallic nanozymes for selective and sensitive CEA detection, eliminating labeling steps.

Noble metal nanoparticles (NPs) exhibit superior plasmonic, catalytic, electronic, and magnetic properties upon alloying with a second metal. However, the synthesis of bimetallic alloy NPs of non-spherical morphologies presents a challenge due to the necessity of concurrently modulating the nucleation and growth kinetics of various metallic constituents. In this study, a simple solution-phase reaction between a phosphine-protected copper nanocluster (NC), namely [Cu(DPPE)H] [DPPE = 1,2-bis(diphenylphosphino)ethane] (abbreviated as Cu) and gold nanotriangles (AuNTs) is reported as a straightforward strategy to obtain gold-copper alloy nanotriangles (AuCuNTs) while keeping their sizes and sharp edges intact.

Diabetic wound healing presents serious clinical challenges due to the unique wound microenvironment characterized by hyperglycemia, bacterial infection, excessive oxidative stress, and hypoxia. Herein, a copper peroxide (CuO)-coated AuCu bimetallic aerogel is developed that exhibits quadruple enzyme-mimicking activity and HO/O self-supplying to modulate the complex microenvironment of methicillin-resistant staphylococcus aureus (MRSA)-infected diabetic wounds. The AuCu@CuO aerogels demonstrate favorable photothermal properties and mimic four enzyme-like activities: peroxidase-like activity for producing toxic reactive oxygen species; catalase-like activity for decomposing HO to release O to relieve oxidative stress and hypoxia; glucose oxidase-like activity for reducing excessive blood glucose and glutathione peroxidase-like activity for balancing abnormal glutathione level.

The electrochemical reduction of CO is a promising approach to mitigate global warming by converting CO into valuable industrial chemicals such as CO. Among the various CO-electroreduction catalysts investigated, AuCu alloys have proven to be particularly promising as they exhibit even higher activity and selectivity toward CO production compared to pure Au, which can be considered as one of the state-of-the-art catalysts for this reaction. In a recent study, we showed that unsupported AuCu aerogels feature an appealing CO-to-CO activity and selectivity, even if in their as-synthesized form they were not phase-pure but instead contained Cu oxide.
