Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Three‐dimensional nitrogen‐doped graphene microspheres (3D NGSs) were prepared by using integrated precursor‐assisted chemical vapor deposition and the hydrothermal method. The 3D NGSs, with an interconnected network structure, show a high crystallization degree, abundant pore channels, and appropriate nitrogen doping. Electrochemical studies confirm that the glucose oxidase/NGSs electrode shows excellent catalytic activity with a high sensitivity of 15.89 μA mM⁻¹ cm⁻², over a wide linear range of 0.1–3.7 m<sc>M</sc>, and fast response time of 3.6 s.</p> </abstract>
