Highly active, stable, and cost-effective enzyme-mimicking nanomaterials (nanozymes) hold the potential to be an alternative to replace natural enzymes for the catalysis of enzyme-like reactions in various applications. Here, novel 3D ruthenium-based metal-organic gels (Ru-MOGs) with fibrillar network structures have been successfully synthesized using a facile one-step strategy at room temperature. Surprisingly, the developed 3D fibrillar networked Ru-MOGs simultaneously possess intrinsic horseradish peroxidase and
NADH peroxidase
mimetic activities. Meanwhile, the horseradish peroxidase mimetic catalytic activity displays well in both acidic environment and alkaline condition. Kinetic analysis reveals that Ru-MOGs make an effective peroxidase mimic with exceptionally high catalytic velocity (

These easily synthesized Ru-MOGs as highly active and novel nanozymes not only suggests a bright future for the nanomaterials as enzyme mimics but also provides new insights into the properties of MOGs, greatly broadening and advancing their applications in biocatalysis and bioassays.
