The rate of cellulose hydrolysis is critically dependent on the ratio of CuCl 2/PdCl 2 in [EMIM]Cl solvent while the total catalyst loading (mol% CuCl 2 + mol% PdCl 2) is unchanged. The results of a combination of physical characterization methods for the catalytic system indicate that Cu(II) was re...
