Fabrication of a porous NiFeP/Ni electrode for highly efficient hydrazine oxidation boosted H₂ evolution

Abstract

Rational optimization of non-noble metal nanomaterials' surface electronic states and physical structures is essential to improve their electrocatalytic performance. Herein, we report a facile dual-regulating strategy to fabricate NiFeP/Ni (P-NiFeP/Ni)...

RuP Nanoparticles Supported on N, O Codoped Porous Hollow Carbon for Efficient Hydrogen Oxidation Reaction

“…The porous structure could provide a larger specific area, expose more active sites and facilitate mass transport. [ 22 ] Morever, the confined environment could protect RuP nanoparticles from oxidation. [ 19 ] In addition, Compared to the Ru/NOC shown in Figure S2 in the Supporting Information, the RuP/NOC offers a relatively smaller particle size with an average particle size of about 3 nm (Figure S3, Supporting Information).…”

Controlled synthesis of trimetallic nitrogen-incorporated CoNiFe layered double hydroxide electrocatalysts for boosting the oxygen evolution reaction

“…The Fe 2+ peaks at 710.1 eV and Fe 3+ at 712.6 eV were observed in the Fe 2p 3/2 region, along with Fe 2+ and Fe 3+ peaks at 722.9 eV and 725.7 eV, respectively, in the Fe 2p 1/2 region. 42 43,44 The high-valence species enrichment can enhance the electro-oxidation reactions, 43 which helps improve the OER performance.…”

Electrochemical Hydrogen Generation by Oxygen Evolution Reaction‐Alternative Anodic Oxidation Reactions

“…[109] A porous nanoflower P-NiFeP/Ni also offered a voltage of 0.162 V at 10 mA cm À2 for N 2 H 4 electrolyzer in 1.0 M KOH containing 0.1 M N 2 H 4 . [110] In addition, non-noble metal electrocatalysts for N 2 H 4 electrolysis were also investigated. Zhang et al designed bifunctional tubular cobalt perselenide (CoSe 2 ) NS as both anode and cathode, which required a cell voltage of 0.164 V to deliver 10 mA cm À2 with 98.3% FE for H 2 generation in 1.0 M KOH containing 0.5 M N 2 H 4 (Figure 16a-c).…”
