Designing cost-effective alkaline water-splitting electrocatalysts is essential for large-scale hydrogen production. However, nonprecious catalysts face challenges in achieving high activity and durability at a large current density. An effective strategy designing high-performance regulating the active electronic states near Fermi-level, which can improve intrinsic increase number of sites. As proof-of-concept, it proposes one-step self-assembly approach to fabricate novel metallic...
Bacteria contamination in drinking water and medical products can cause severe health problems. However, currently available sterilization methods, mainly based on the size-exclusion mechanism, are typically slow require entire contaminated to pass through filter. Here, we present an electroresponsive hydrogel approach for bacteria adsorption removal. We successfully engineered a series of graphene oxide hydrogels using redox-active ruthenium complexes as noncovalent cross-linkers. The...
