“…Since the first report of spin catalysis in 1994, 21 it has been found that many spin carriers can serve as spin catalysts, which makes it possible to overcome spin conservation rules in basic chemical reactions, thus increasing the possibility of chemical reaction success. 22 , 23 , 24 There are two important mechanisms of spin catalysis: (1) Exchange (nonmagnetic) interactions of electron spins, and (2) dipole-dipole interactions of electron spins through their magnetic dipoles. 23 Carbon, being abundantly available, is a very promising candidate for constructing carbon-based materials that can act as metal-free catalysts with different electronic states and molecular structures.…”
