Rotating disk electrode measurements of activity and stability of monolayer Pt on tungsten carbide disks for oxygen reduction reaction

Preparation of cobalt silicide on graphene as Pt electrocatalyst supports for highly efficient and stable methanol oxidation in acidic media

“…The electrochemical oxidation of methanol has been considered to be an attractive power source with potential applications over the past decades in the direct methanol fuel cells (DMFCs), which has high-energy conversion efficiency, system simplicity, environmental friendliness, low operating temperatures and the storage convenience of a liquid fuel cell [1][2][3][4]. The electrocatalyst is one of the critical parts, noble metals such as Pt and Pd have been remaining the main active ingredients of the electrocatalyst [5].…”

Oxygen adsorption and dissociation during the oxidation of monolayer Ti2C

“…[41][42][43] Therefore, it is necessary to explore the thermodynamic stability of Ti 2 C in an oxidizing environment. We have carried out MD simulations for oxygen saturated Ti 2 C (i.e., Ti 2 CO 2 ) at an intermediate temperature of 823 K in a 2 Â 3 supercell.…”

An ultrastable bimetallic carbide as platinum electrocatalyst support for highly active oxygen reduction reaction

“…The electrochemical stability has also improved by replacing carbon materials with carbides as catalyst support [21e25]. However, the stability of the carbide-based electrocatalyst should be further improved [26] for commercial applications.…”
