Single-atom nanozymes (SAzymes) with ultrahigh atom utilization efficiency have been extensively applied in reactive oxygen species (ROS)-mediated cancer therapy. However, the high energy barriers of reaction intermediates on single-atom sites and overexpressed antioxidants tumor microenvironment restrict amplification oxidative stress, resulting unsatisfactory therapeutic efficacy. Herein, we report a multi-enzyme mimetic MoCu dual-atom nanozyme (MoCu DAzyme) various catalytic active sites, which exhibits peroxidase, oxidase, glutathione (GSH) nicotinamide adenine dinucleotide phosphate (NADPH) oxidase mimicking activities. Compared Mo SAzyme, introduction Cu atoms, formation synergetic effects among enhance substrate adsorption reduce barrier, thereby endowing DAzyme stronger Benefiting from above enzyme-like activities, can not only generate multiple ROS, but also deplete GSH block its regeneration to trigger cascade stress. Additionally, strong optical absorption near-infrared II bio-window endows remarkable photothermal conversion performance. Consequently, achieves high-efficiency synergistic treatment incorporating collaborative therapy This work will advance applications DAzymes provide valuable insights for nanocatalytic

Carbon-based nanocomposites with atomically dispersed transition metals have been found to exhibit excellent electrocatalytic activity toward the oxygen evolution reaction (OER). Yet, low metal loads and severe electrooxidation of carbon greatly limit stability. Reducing pyrolysis temperature can weaken aggregation atoms, using aerogel as a 3D scaffold maximize accessible sites. Simultaneously, lower provide higher content for substrate enhance resistance against electrooxidation. Herein, aerogels embedded Fe–Ni dual atom centers (NCA/FeNi-500) are synthesized by controlled at 500 °C chitosan hydrogel composite along FeCl3 NiCl2. With an loading 4.35 wt %, NCA/FeNi-500 exhibits remarkable OER catalytic in both alkaline water simulated seawater, featuring overpotential only +294 +306 mV reach current density 10 mA cm–2, respectively, long-term stability during overall splitting, performance much better than those commercial RuO2. First-principles calculations show that adjacent NiN4 sites effectively promote kinetics FeN4 reducing energy barrier O–O formation. This is also manifested saline splitting.
