(A) Cyclic voltammetry of the various nanomaterials prepared without mechanical exfoliation, with sonication and shear, as well as Pd-NP, EG, and bare carbon paper. (B) The associated integration of the curve for the desorption charge for nanomaterials with Pd deposition. (C) LSV after holding the potential at −0.300 V for 5 min and varying the starting potential from −0.300 to −0.040 V. (D) Overall hydrogen desorption charge, QH, obtained from integration of LSVs of the various nanomaterials including Pd-NP, Pd-EG, Pd-ShEG, and Pd-sEG.
