Coordinated regulation of phosphorus/nitrogen doping in fullerene-derived hollow carbon spheres and their synergistic effect for the oxygen reduction reaction

Abstract

Fullerene-derived carbons have been demonstrated as effective electrode materials for electrocatalytic reactions. The heteroatoms in the carbon matrix are essential to enhance their electrocatalytic performance but are still challenging for...

Bulk synthesis of conductive non-metallic carbon nanospheres and a 3D printed carrier device for scanning electron microscope calibration

“…In this regard, hollow carbon spheres (HCS) have shown to possess excellent electrical conductivity and can fulll the requirements of CRMs. [8][9][10][11][12][13][14] However, CRMs also need to have a high level of mechanical strength. Hence, a material like silicon dioxide (SiO 2 ) that has superior mechanical strength with controlled uniform spherical morphology can be used as the core material for HCS to enhance its mechanical strength.…”
