ZIF-67-derived nanoframes as efficient bifunctional catalysts for overall water splitting in alkaline medium

“…4f, CoP/CNTHPs maintained 88.6% of the original current density, further verifying its prominent stability in the HER process. 53…”

“…4f, CoP/CNTHPs maintained 88.6% of the original current density, further verifying its prominent stability in the HER process. 53 Under the same experimental conditions, the activity of the samples for OER in 1.0 M KOH was also systematically studied. In Fig.…”

Three-dimensional reduced graphene oxide decorated with cobalt metaphosphate as high cost-efficiency electrocatalysts for the hydrogen evolution reaction

“…22,32,33 Carbon materials include carbon black, carbon nanotubes, graphene and their derivatives. 12,15,36,37 Among the above materials, we choose three-dimensional graphene as the support of the catalyst, which has the advantages of large specic surface area, interconnected ordered pore structure, abundant active sites, excellent electrical conductivity, lightweight and good mechanical strength comparing with other carbon materials. 22,34,35 These advantages can enhance the electron transport capacity of the electrocatalyst, increase the contact area between the catalyst and the electrolyte solution, and accelerate the release of reaction gases.…”

Enriched sp2-Hybridized C Atoms toward the Tradeoff between Activity, Conductivity and Stability of Spherical Porous Metal–Nitrogen–Carbon Catalysts for Rechargeable Zinc–Air Batteries

“…In comparison to sp 3 -Cs, sp 2 -Cs usually show excellent conductivity and stability. 30 Many studies focusing on sp 2 -C (such as graphene 31,32 and carbon nanotubes 33 ) on carbon-based electrocatalysts were performed thereafter. Zhao et al prepared a 3D interconnected hierarchical porous graphene mesh with a robust conductive network through self-assembly and chemical etching of reduced graphene oxide.…”
