DehydrogenationThe dehydrogenation of saturated organic molecules is utilized for hydrogen production from potential hydrogen energy carriers, and for fundamental oxidation protocols in the manufacture of commodity chemicals. Catalytic dehydrogenative transformations can be divided into: (1) the decomposition of hydrogen storage compounds including formic acid[1–4 ...
