Boosting Electrocatalytic H2O2 Production via Two-Electron Water Oxidation Driven by the Solid-Solution Effect in Bi2Mo x W1− x O6 Hollow Nanostructures

The electrochemical two-electron water oxidation reaction (2e−-WOR) offers a sustainable route for on-site H2O2 production, yet developing efficient and stable electrocatalysts remains challenging. Herein, cation-ratio engineering is employed to tune the performance of hollow-structured Bi2MoxW1−xO6 solid solutions....

Allosteric Switching-Triggered Electrocatalyst Recruitment Enables Indicator-Free, Milliampere-Level Hydrogen Evolution Readout for MicroRNA-21 Detection

Electrochemical nucleic acid biosensors typically rely on redox labels or exogenous mediators to generate analytical signals, which can complicate assay design and constrain signal magnitude. Herein, we report an enzyme-free and indicator-free electrochemical biosensor for microRNA-21 based on allosteric switching-tr...
