Investigating the radical properties of oxidized carbon materials under photo-irradiation: behavior of carbon radicals and their application in catalytic reactions Oxidized carbon materials have abundant surface functional groups and customizable properties, making them an excellent platform for generating radicals.

Visible-light-responsive nanocarbon was systematically synthesized via a one-step hydrothermal method, using citric acid and Congo Red; this nanocarbon exhibited visible-light absorption at 516 nm and photocatalytic activity for the carbon–carbon bond-forming reaction between benzylamine and ethyl cyanoacetate. Mechanistic investigations proved that this system generates radicals and the reactions proceed via radical pathways, which are confirmed by electron spin resonance.
