Platinum Nanoparticles Anchored on Flowerlike Zinc Oxide Nanosheet Array Electrocatalysts for Efficient Hydrogen Evolution Reaction

“…After that, the H* reacts (via proton-coupled electron transfer) with a new set of H 3 O + + e – to form H 2 . The proposed electrocatalytic mechanism of the electrocatalyst Pt@ZnO/CFP can be expressed as follows: On the surface of Pt@ZnO/CFP, water molecules construct a double electric layer where strong interactions between oxygen atoms and metal atoms (Zn, Pt) weaken the H–OH bond . Adsorbed H* is generated by first combining H 3 O + from the acidic electrolyte with the electrons on the surface of ZnO nanosheets.…”

“…In general, the HER performance of Pt@ZnO/CFP is comparable to most reported zinc-based hydrogen evolution electrocatalysts (Table ). − It can be found that the platinum nanoparticles anchored on the flowerlike zinc oxide nanosheet array electrocatalyst exhibit better HER performance.…”

“…42 The proposed electrocatalytic mechanism of the electrocatalyst Pt@ZnO/CFP can be expressed as follows: On the surface of Pt@ZnO/CFP, water molecules construct a double electric layer where strong interactions between oxygen atoms and metal atoms (Zn, Pt) weaken the H−OH bond. 43 Adsorbed H* is generated by first combining H 3 O + from the acidic electrolyte with the electrons on the surface of ZnO nanosheets. Meanwhile, the Pt nanoparticles as active centers produce a strong synergistic effect with the surface of ZnO nanosheets, accelerating the electron transfer and the precipitation of adsorbed H*.…”

An iron phosphate hydroxide hydrate electrocatalyst: synergistic effects of Fe2+ and Fe3+ for enhanced hydrogen evolution reaction stability

“…[29][30][31][32] The phosphate group has drawn attention since its P-O bond weakens the M-O bond, which is advantageous for an electrocatalyst. [33][34][35][36] On the other hand, the optimization of proton and hydroxide adsorption is the rst step in the hydrogen evolution reaction. 37 The most commonly used 3D porous metal foams are excellent current collectors and show intrinsic catalytic activity when combined with a monolithic catalyst due to their synergistic effect.…”
