Heterogeneous catalysts supported on activated carbons. These solid materials consist of different activated carbons containing platinum particles finely dispersed on them.
The platinum particles are anchored on the activated carbon surface by means of an SMSI bond (Strong Metal Support Interaction). This bond is formed between the platinum coordination sphere and the oxygenated functional groups on the carbon surface (SOGs).
Using a heterogeneous platinum catalyst causes platinum particles to chemically interact, altering the reaction’s kinetics (lowering the activation energy) without affecting its thermodynamics. (ΔG).
