Toward a unified metric of catalyst comparison in polymer hydrogenolysis

To date, research in plastic hydrogenolysis has lacked an efficient, standardized method to benchmark catalyst performance. In this issue of Chem Catalysis, Pérez-Ramírez and coworkers demonstrate a new metric, named scission preference, to compare catalysts and elucidate the reaction mechanism for the hydrogenolysis of polypropylene.
