Metal doping and Hetero-engineering of Cu-doped CoFe/Co embedded in N-doped carbon for improving trifunctional electrocatalytic activity in alkaline seawater

Rapid synthesis of efficient Mo-based electrocatalyst for the hydrogen evolution reaction in alkaline seawater with 11.28% solar-to-hydrogen efficiency

“…4a shows the LSV curves. Encouragingly, the required overpotential for the current density of 10 mA cm −2 with MoNi 4 /MoO x was only 15 mV in alkaline seawater electrolyte, exceeding that for Ni@NF, Mo@NF, Pt/C, and other reported catalysts 42–50 (Fig. 4b).…”

Water electrolysis for hydrogen production: from hybrid systems to self-powered/catalyzed devices

“…This OHzS system saved 3.35 kW h for generating 1.0 m 3 of H 2 in comparison with a N 2 H 4 -free system. Additionally, Wang's group has successfully fabricated other doped catalyst systems such as Cu-doped CoFe/Co encapsulated by N-doped carbon, 206 Fe/Co dual-doped Ni 2 P and MIL-FeCoNi heterostructure arrays, 207 self-supporting Ru-doped FeP 4 nanosheets, 208 and Fe-doped Ni 2 P/ CoP encapsulated by nitrogen-doped carbon layers. 209 These catalysts have demonstrated promising HzOR and HER activity, further showing the potential of doped catalyst systems for efficient hydrazine-assisted water electrocatalysis.…”

Recent advances in trifunctional electrocatalysts for Zn–air batteries and water splitting

“…3G–I). 22 Additionally, the Ag species were also used to optimize the electronic structure of the CoFe alloys, which were encapsulated in the graphitic carbon shell. The nanocomposite not only displayed the improved charge transfer ability, but also generated a synergistic effect and more active sites at the interface, significantly boosting the trifunctional electrocatalytic activities for the ORR, OER, and HER.…”

“…Recently, many trifunctional electrocatalysts have been investigated including transition-metal-based (including alloys, hydroxides, phosphides, chalcogenides, and nitrides) composites, [21][22][23][24][25] single-atom-metal nanomaterials, 26 carbon materials, 27 metal organic frameworks (MOFs), 28 and MOF-derived nanomaterials. 29 However, their unsatisfactory activities limit the prospects of industrial applications.…”
