摘要： The present invention belongs to the field of catalytic chemistry, and more specifically to catalysed reduction chemical reactions, preferably of CO 2 into small molecules.
The present invention relates to a new catalyst compound comprising at least a copper (Cu) layer, wherein the copper layer is functionalized with at least one aryl group and its use thereof in a reduction chemical reaction, preferably in reduction of CO 2 into CO, ethylene and other small molecules such as gaseous hydrocarbons (methane, propane) or liquid molecules (ethanol, formic acid, propanol). The invention relates to the process of manufacture of said catalyst compound and to a process electrochemical conversion of CO 2 to small molecules and in particular ethylene.-

摘要： The present invention relates to a method of manufacturing an electrolytic copper foil, the method comprising:
preparing an electrolyte; and
performing electroplating using the electrolyte to form a copper layer,
wherein the electrolyte includes copper ions at a concentration of 50 g/L to 100 g/L, a sulfuric acid at a concentration of 50 g/L to 150 g/L, chlorine (Cl) at a concentration of 1 ppm to 50 ppm, lead ions (Pb 2+ ) at a concentration of 0.25 g/L, and an organic additive, and
the formation of the copper layer includes applying a current at a current density of 40 A/dm 2 to 80 A/dm 2 between an electrode plate and a rotating drum disposed to be spaced apart from each other in the electrolyte.-

摘要： A surface-treated steel sheet in which contact resistance is low and which can suppress the occurrence of a change in the color of the surface thereof is provided. A surface-treated steel sheet of the present disclosure includes a steel sheet, and an Ni-Co-Fe alloy layer containing Ni, Co, and Fe on the steel sheet surface. In the thickness direction of the Ni-Co-Fe alloy layer, a Co concentration in the Ni-Co-Fe alloy layer is highest at a position which is on an outermost surface side of the Ni-Co-Fe alloy layer relative to a position where the Ni concentration is highest in the Ni-Co-Fe alloy layer, and which is between the outermost surface of the Ni-Co-Fe alloy layer and a depth of 100 nm from the outermost surface. In the Ni-Co-Fe alloy layer, an Ni-concentrated region in which the Ni concentration increases toward the outermost surface of the Ni-Co-Fe alloy layer is formed between the outermost surface of the Ni-Co-Fe alloy layer and the position where the Co concentration is highest.

摘要： Provided are a hot-pressed member, a steel sheet for hot pressing, and methods for producing the hot-pressed member and the steel sheet for hot pressing. A hot-pressed member according to the present invention includes a steel sheet and a Zn-based alloy coated layer disposed on at least one surface of the steel sheet. The Zn-based alloy coated layer includes a solid solution phase including Zn with the balance being Fe and incidental impurities, an intermetallic compound phase including Fe with the balance being Zn and incidental impurities, and an oxide layer including Zn. The oxide layer serves as an uppermost layer of the Zn-based alloy coated layer and splits the intermetallic compound phase. The split density in at least one cross-section of the oxide layer per unit cross-section is 10 split positions/mm or more.
