Carbonized Wood Decorated with Cobalt‐Nickel Binary Nanoparticles as a Low‐Cost and Efficient Electrode for Water Splitting

“…That is, the Co/Ni-CW catalyst requires the lowest overpotential of 330 mV to achieve 10 mA cm -2 , and a large current density of 68.5 mA cm -2 at 410 mV, demonstrating the large current densities at small cell voltage for overall water splitting. Additionally, the Co/Ni-CW with a low overpotential at the current density of 10 mA cm -2 can also be competitive against those of representative Ni and Co-based electrocatalysts, [25][26][27][28][29][35][36][37][38] suggesting the effective activity of Co/Ni-CW toward OER (Figure 4b).…”

Ultrafast Joule heating-induced formation of amorphous CoFeNi phosphate for efficient and stable oxygen evolution reaction

“…Characterization methods, including CV, HAADF-STEM, EDS, XPS, and Raman spectroscopy, corroborated that Joule heating directly formed a multimetallic phosphate with an amorphous structure and promoted the preoxidation of active cation species, facilitating surface reconstruction and oxyhydroxide formation during electrolysis. This transient thermal processing approach can be readily adapted to create amorphous structures of various functional materials, including metal alloys, 35,38 oxides, 15,73,74 nitrides, [75][76][77] suldes, 78,79 and other phosphorous-based structures on alternative 2D substrates, [79][80][81][82] presenting signicant potential for advanced energy storage and conversion applications.…”
