Abstract
ABSTRACT Black carbon materials are widely used due to their low cost, abundance, and easy modification, but their photocatalytic application is limitedss by rapid solar‐to‐thermal conversion. Here, synergistic F/N co‐doping was developed to enhance the photocatalytic performance of amorphous carbon materials (aCMs) by creating charge localization sites that promote electron‐hole separation. Kelvin probe force microscopy (KPFM) and surface photovoltage (SPV) measurements indicate that F/N co‐doping can establish a stronger internal electric field within the aCMs. A comprehensive suite of spectroscopic analyses reveal that the F/N‐aCMs exhibits a lower exciton binding energy (14.60 meV), faster relaxation time…
