Abstract:
The design of efficient and stable non-noble metal electrocatalysts for hydrogen generation in hydrogen-based clean energy technologies is a great challenge. We demonstrated a new approach of synthesizing bimetallic carbide nanoframes by a novel method at low temperature via a brand-new synthesis mechanism, and were applied as high performance electrocatalysts for H2 generation. The open-framework structured bimetallic carbide nanoframes consist of nanosegregated polycrystals with three-dimensional porous surface, and exhibit high activity and stability with small onset overpotential of 15mV versus the reversible hydrogen electrode (RHE), low overpotentials of 154mV at 10mAcm⁻² and 183mV at 20mAcm⁻², and small Tafel slope of 49mVdec⁻¹.
