COBALT ON TUNGSTEN TITANIUM CARBIDE MXene

Resumen de: US20260009146A1

We synthesized a tungsten titanium carbide (W2TiC2) MXene. By loading cobalt onto the surface of W2TiC2, we developed an effective and stable catalyst for an alkaline hydrogen evolution reaction. The catalyst exhibited a small overpotential of 63 mV at 10 mA/cm2 and a low Tafel slope of 44.3 mV/dec. At high current density of 100 mA/cm2 and 1000 mA/cm2, low overpotentials of 191 mV and 408 mV were achieved, outperforming commercial Pt/C electrodes. Under both current ranges, our catalyst exhibited excellent stability of 500 h at 10 mA/cm2 and for 100 h at 1000 mA/cm2 without any degradation. In flow cell tests, by pairing with Ni foam, our catalyst required much lower cell voltage than commercial Ni foam Pt/C and maintained ̃100% H2 faradaic efficiency over 15 h of continuous tests from 50 to 400 mA/cm2. Under more demanding industry-level conditions, the catalyst maintains the incredible performance, exhibiting an excellent stability of at least 1000 h at 4000 mA cm−2 in 1 M KOH.
