Ultrathin Nitrogen-Doped Carbon Coated with CoP for Efficient Hydrogen Evolution

Abstract: Searching for non-noble metal based electrocatalysts with high efficiency and durability toward hydrogen evolution reaction (HER) is vitally necessary for the upcoming clean and renewable energy systems. Here we report the synthesis of CoP nanoparticles encapsulated in ultrathin nitrogen-doped porous carbon (CoP@NC) through a metal-organic framework (MOF) route. This hybrid exhibits remarkable electrocatalytic activity toward HER in both acidic and alkaline media, with good stability. The experiment and the… Show more

“…[11][12][13][14][15] The high-performance catalytic activities of these materials may be related to the function of their heteroatoms, such as phosphorus, which possesses lone-pair electrons in 3p orbitals and vacant 3d orbitals and can thus accommodate the surface charge as well as induce local charge density. [17][18][19][20][21] Taking all the above works together, we predicted that nitrogen (N)-doped molybdenum carbide and phosphide hybrids, N@MoPCx, might be promising electrocatalysts for efficient hydrogen evolution. [17][18][19][20][21] Taking all the above works together, we predicted that nitrogen (N)-doped molybdenum carbide and phosphide hybrids, N@MoPCx, might be promising electrocatalysts for efficient hydrogen evolution.…”

“…The O 1 s spectrum in Figure S7b, Supporting Information, can again confirm the result. The O 1 s yields three distinct peaks that are well matched to P–O, C–O, and Co–O, which are located at 533.2, 531.9, and 531.3 eV, respectively …”

“…The TMPs are easily oxidized to metal oxides or hydroxides during the OER process, which greatly reduce the electronic conductivity of TMPs, and the OER performance of the material also decreases . Considering carbon materials with remarkable electrical conductivity, a high specific surface area, and good durability, the TMPs can be covered by carbon material to improve the stability and electrocatalytic performance . Bao and co‐workers successfully synthesized pea‐like M x P nanoparticles decorated with N‐doped porous carbon nanofibers (M x P@NPCNFs) and found that M x P@NPCNFs have a remarkable electrochemical performance .…”

“…[86b] Recently,M OFs have frequently been utilized to fabricate composites in whicht he TM componentsa re covered by at hree-dimensional N-C matrix. [79,108,122,158] The controllable morphology of the MOFs can be mostly maintaineda fter ap yrolysis process, and consequently,t he desired morphology of the materials can be designed and controlled before heat treatment. Therefore, methods depending on MOFs can be considered efficient synthesis strategies for the preparation of electrocatalysts in which the TM components are covered in the N-C substrates.…”
