Ru-doped 3D porous Ni3N sphere as efficient Bi-functional electrocatalysts toward urea assisted water-splitting

Strain and Shell Thickness Engineering in Pd3Pb@Pt Bifunctional Electrocatalyst for Ethanol Upgrading Coupled with Hydrogen Production

“…Notably, the Pd 3 Pb@2.9%Pt demonstrated promising activity for the hybrid electrolyzer system, with cell voltages as low as 0.75 V required to reach current densities of 10 mA cm −2 . In contrast, a conventional alkaline electrolysis cell assembled with 1 m KOH as the electrolyte and [52][53][54][55][56][57][58][59][60][61][62][63][64][65][66] The materials indicated on the bars are the catalysts used for the corresponding small molecule oxidation reaction.…”

Designing bifunctional catalysts for urea electrolysis: progress and perspectives

“…For example, introducing Co into the Ni–P–O catalyst decreases the conversion potential of Ni 2+ /Ni 3+ and the UOR onset potential; for HER, the Co dopant enhances the water dissociation ability of Ni(OH) 2 and the hydrogen desorption process of NiP. 173 For the V-doped Ni 3 N, 174 Ru-doped Ni 3 N, 175 and Mo, Fe co-doped Co 2 P, 77 dopants have been evidenced to regulate the adsorption of reaction intermediates and lead to near zero Gibbs free energy. Aside from most metal-doped pnictides, oxygen-incorporated NiMoP developed by Jiang et al shows upgraded performance for urea electrolysis.…”

“…The urea electrolysis performance of five novel metal-involved catalysts has been tested in 1 M KOH + 0.33 M urea, including Pt/D-NiCo LDH (1.32 V), 195 P-modified AuRh (1.33 V), 85 Rh/NiV-LDH (1.336 V), 63 NiFeRh-LDH (1.35 V), 120 and Ru-Ni 3 N@NC (1.41 V). 175 In these catalysts, the presence of noble metals can enhance the catalytic performance. Especially, using noble metals as dopants and SACs can improve their utilization efficiency and limit the fabrication cost of catalysts.…”

Corrosive engineering assistedin situconstruction of an Fe–Ni-based compound for industrial overall water-splitting under large-current density in alkaline freshwater and seawater media

“…Therefore, the development of largescale, low energy consumption, and high-stability nonprecious metals for water-splitting, especially those suitable for industrial applications, is a great challenge. 11,12 In recent years, numerous electrocatalysts based on non-noble metals, such as transition metal phosphide (TMP), 13 transition metal boride (TMB), 14,15 transition metal sulde (TMS), 16 and transition metal nitride (TMN), 17,18 have been extensively studied. Due to their high intrinsic catalytic activity, exible structure, and composition, transition metal nitrides have emerged as potential electrocatalysts with excellent catalytic performance and are superior to Pt and RuO 2 .…”
