Exceptional photocatalytic enhancement of graphene-semiconductor composites has been widely reported, but our understanding of the role that graphene plays in this enhancement remains limited, which arises from the difficulty of precisely controlling graphene hybridization. Here we present a general platform of a graphene-semiconductor hybrid panel (GHP) system wherein a precise number of layers of graphene are hybridized with photoactive semiconductors (e.g.

- High-performance hydrogen peroxide sensors can indicate biological interactions and diseases, with low-cost metal oxides showing promise, though they face issues like low conductivity.
- Multi-component metal oxides have improved potential for overcoming these challenges, but their inconsistent composition complicates material preparation.
- This research presents a redox preparation method that produces homogeneous, noble metal-free cobalt manganese oxide sensors, achieving high conductivity and sensing activity, with significant improvements in detection range and sensitivity associated with controlled material properties.
A general redox procedure was successfully developed for the controlled synthesis of substituted cobalt oxides with hierarchical flower-like nanostructures comprising unique Y-shaped interconnections. The substitution and nanostructures synergistically enhance the material's electrochemical activities for highly efficient sensing of H2O2.
