1. Different classes of catalysts and their physico-chemical properties

1.1 Nature of sites according to catalysts

Solid catalysts can be divided into two categories [J 1 250] :

  • conductors of electric current: metals and semiconductors are active in redox reactions. Their catalytic action can be linked to their role as reservoirs of electrons, which can then be exchanged with the reactants;

  • insulators which catalyze reactions attributable to acids or bases in homogeneous catalysis: dehydration,...
