Large-scale synthesis of mesoporous carbon microspheres with controllable structure and nitrogen doping using a spray drying method

Abstract

A low-cost and high-throughput spray drying method was developed to produce mesoporous carbon microspheres with controllable structure and nitrogen doping. The obtained microspheres have spherical morphology, controllable nitrogen doping (0–7 wt%), high specific surface areas (900–1200 m² g⁻¹), large pore volumes (1–3 cm³ g⁻¹), and large mesopores.
