Differentiation of Ni3C crystalline phase from hexagonal-close-packed Ni phase in ethylene glycol-mediated sol–gel process and excellent catalytic behavior of Ni/N-doped C nanomaterials toward hydrogenation reduction reaction of 4-nitrophenol

Nickel nanoparticle/carbon catalysts derived from a novel aqueous-synthesized metal-organic framework for nitroarene reduction

“…It is not straightforward to compare the behaviour of different catalysts reported in the literature because the conditions under which they are tested differ in the amount of catalyst used, the concentration of the reagents, the volume of the reactor and the temperature, which all have an effect on the catalyst activity. Table S3 lists different kinetic parameters and Act Ni for a series of Ni catalysts supported onto carbon materials reported in the literature [7,10,22,25,29,31,32,[57][58][59][60][61]. In several of these works, the kinetic studies were carried out in UV-Vis spectrophotometer cuvettes (volume < 3 mL)…”

Uniform nodule-like Ni3C/Ni heterostructure templated by metal–organic frameworks for high-performance overall water splitting

“…2b), the shoulder peak at a binding energy of 852.4 eV is associated with the presence of metallic Ni. 42 Moreover, the binding energy peak of Ni 3 C/Ni@NF at 853.8 eV corresponds to the Ni–C bond, demonstrating the existence of the Ni 3 C phase. 16,43 The other two characteristic peaks of Ni 2p 3/2 at 855.7 eV and its corresponding shakeup satellite peak at 861.1 eV can also be observed.…”
