Fig. 3

Online ICP-MS dissolution data obtained for successive cyclic voltammograms (CVs) with varying lower potential limit (LPL) values for (a) Mo (blue) and (b) S (yellow) in c-MoS2 (dark) and a-MoS3-x (pale). Dissolution rates expressed as material loss (M: either Mo or S) per time and catalyst geometric area. CVs recorded from 0 VRHE to UPLs in the range −0.1 ≤ EUPL ≤ −0.3 V. Scan rate: 5 mV s−1.
