WebApr 13, 2024 · In this contribution, within the framework of computational hydrogen model and constant-potential implicit solvent model, the NORR electrocatalyzed by a novel transition-metal-anchored SnOSe armchair nanotube (TM@SnOSe_ANT) was investigated using density functional theory calculations. WebApr 14, 2024 · The exchange current density can be obtained via the relative intercept. The relevant data values are presented in Table 2. As shown in Figure 5b, the Tafel slope and the exchange current density of the Pt/WC catalyst are 30 mV·dec −1 and 0.829 mA·cm −2, respectively. For the pure WC catalyst, the Tafel slope is 88 mV·dec −1. The small ...
