Table 3. Summary of the HER Performance of Rhenium-Based Phosphides and Borides.
| system | mass loading (mg cm–2) | mass activity (Ag–1) | overpotential (η10 in mV at 10 mA cm-2a) | Tafel slope (mV dec–1) | ref |
|---|---|---|---|---|---|
| Re3P4 NP | 0.143 | 69.9 | 40 | 38 | (167) |
| Ru-doped Re3P4/N,P-doped carbon | 1.6 | 6.30 | 88 | 53.18 | (163) |
| ReB2 | 0.46 | 21.7 | 160 | (168) |
Current density at which the overpotential was measured is explicitly mentioned when it differs from 10 mA cm–2.
