The mechanisms for the resistance to sulfur poisoning at the triple phase boundary (TPB) of the Ni/yttria-stabilized zirconia (YSZ) system treated with Sn vapor are studied using the first-principles method based on density functional theory. Models with Sn dopant or adsorbate are proposed. It is found that the TPB model of the Ni/YSZ system with Sn dopant in Ni can to some extent restrain the ...

Ni-doped diamond like carbon (NiDLC) thin films were deposited on Si substrates by cosputtering a pure Ni target with different DC powers (10, 20, 30, and 40 W) and a pure graphite target with a DC power of about 650 W at room temperature. X-ray photoelectron spectroscopy (XPS) was used to measure the chemical composition and binding energy of the NiDLC thin films, and the C bonding structures ...

Magnetite $({\mathrm{Fe}}_{3}{\mathrm{O}}_{4})$ doped with earth-abundant metals has become a promising catalyst material. In particular, Ni-doped magnetite $(\mathrm{Ni}/{\mathrm{Fe}}_{3}{\mathrm{O}}_{4})$ been demonstrated as cheap, robust, and catalytically active material in photocatalytic electrochemical water oxidation. Recently, the incorporation of Ni atoms ${\mathrm{Fe}}_{3}{\mathrm{O}...

Synthesis of low cost, durable and efficient electrocatalysts that support oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) are the bottlenecks in water electrolysis. Here we propose a strategy for the development of controllably alloyed, porous, and low density nickel (Ni) and cobalt (Co) based alloys - whose electrocatalytic properties can be tuned to make them multifunct...

Ni, Cu and Ni-Cu catalysts supported on high surface area graphite were synthesized by incipient wet impregnation. Also, the effect of doping support with alkali oxides (Li, Na K) was studied. The tested in formic acid decomposition reaction to produce hydrogen. bimetallic catalyst doped K showed best catalytic performance 100% conversion at 130 °C a 95% selectivity turnover frequency (TOF) fol...
