NiFe Layered-Double-Hydroxide Nanosheet Arrays on Graphite Felt: A 3D Electrocatalyst for Highly Efficient Water Oxidation in Alkaline Media

Inorganic Chemistry, Год журнала: 2021, Номер 60(17), С. 12703 - 12708

Опубликована: Авг. 6, 2021

It is of great importance to rationally design and develop earth-abundant nanocatalysts for high-efficiency water electrolysis. Herein, NiFe layered double hydroxide was in situ grown hydrothermally on a 3D graphite felt (NiFe LDH/GF) as catalyst facilitating the oxygen evolution reaction (OER). In 1.0 M KOH, LDH/GF requires low overpotential 214 mV deliver geometric current density 50 mA cm–2 (η50 = mV), surpassing that LDH supported 2D paper LDH/GP; η50 301 mV). More importantly, shows good durability at within h OER catalysis testing delivers faradaic efficiency nearly 100% electrocatalysis OER.

Hierarchical Structure of CuO Nanowires Decorated with Ni(OH)₂ Supported on Cu Foam for Hydrogen Production via Urea Electrocatalysis

Small Methods, Год журнала: 2021, Номер 6(1)

Опубликована: Ноя. 28, 2021

Owing to the low theoretical potential of urea oxidation reaction (UOR), electrolysis is an energy-saving technique for generation hydrogen. Herein, a hierarchical structure CuO nanowires decorated with nickel hydroxide supported on 3D Cu foam constructed. Combined and experimental analyses demonstrate high reactivity selectivity Ni(OH)2 toward UOR instead oxygen evolution reaction. The creates synergistic effect between two highly active sites, enabling exceptional activity record 1.334 V (vs reversible hydrogen electrode) reach 100 mA cm-2 Tafel slope 14 mV dec-1 in 1 m KOH 0.5 electrolyte. Assembling full driven by this developed electrocatalyst as anode commercial Pt/C cathode provides current density 20 at cell voltage ≈1.36 promising operational stability least 150 h. This work not only enriches material family but also significantly advances production.
