Anisole hydrodeoxygenation over Ni–Cu bimetallic catalysts: The effect of Ni/Cu ratio on selectivity

Chemical vapor deposition of Pd/Cu alloy films from a new single source precursor

“…This offset can be attributed to the formation of Pd-Cu alloys. Indeed, it has been shown that upon formation of a Ni-Cu alloy the Cu2p 3/2 and Ni2p 3/2 lines can be shifted by 0.2 eV and 0.6 eV, respectively [35,36]. Similar results were obtained from the investigation of the sample processed at 350 1C.…”

Influence of Mo on catalytic activity of Ni-based catalysts in hydrodeoxygenation of esters

“…1, the Ni-Cu/Al 2 O 3 catalyst exhibited three major peaks of hydrogen absorption with the maximums at 220, 365, and 525 • C. As compared with the Ni/Al 2 O 3 catalyst, the peaks of Ni-Cu/Al 2 O 3 were shifted toward lower temperatures. The reason for this effect is discussed in detail elsewhere [22]. In fact it is (Fig.…”

“…Taking into account values of the Cu2p 3/2 binding energy and the Auger parameter ˛, which is equal to the sum of the Cu2p 3/2 binding energy and the CuLMM kinetic energy [27], we can speculated that copper in the catalysts exists in the metallic state mainly. Indeed, such Cu2p spectra without highintensive shake-up satellites are typical of copper in both of the Cu 0 and Cu 1+ states [22]. However, bulk metallic copper is characterized by the Auger parameter equal to 1851.4 eV whereas Cu 2 O is characterized by the Auger parameter equal to 1849.4 eV [28].…”

Ni/Al2O3 Catalysts Derived from Layered Double Hydroxide and Their Applications in Hydrodeoxygenation of Anisole

“…As new hydrotreating catalysts, transition metal phosphides and carbides have been studied, [21, 22] by which the selectivity toward heteroatom removal have been kept improving. [23] In addition, nickel‐based catalysts seem to be a promising non‐noble metal catalytic system for anisole because of the high HDO degree, sulfur‐free and low cost, which have been discussed in depth and further modified by bimetal and support …”
