preparation example 1

[0041] A Pt catalyst was deposited on a glassy carbon electrode (5mm OD×4mm H) using a reactive magnetron sputtering machine. Put the Pt target into the sputtering machine, apply power to the Pt target, and pass argon gas (flow rate of 20 sccm) into the machine, and the pressure inside the machine is 30 mTorr. Argon ions are used to strike the Pt target, and sputtering is carried out at room temperature for 5 to 6 minutes to form a Pt catalyst with a film thickness of about 100 nm on the glassy carbon electrode, and the coating amount of the catalyst is 0.042 mg.

Abstract

The invention discloses a nitride catalyst and a formation method thereof. The formation method comprises following steps: placing a Ru target and an M target in a nitrogen containing atmosphere, wherein the M represents Ni, Co, Fe, Mn, Cr, V, Ti, Cu, or Zn; providing power to the Ru target and the M target; and knocking the Ru target and the M target by ions so as to precipitate M<x>Ru<y>N2 on asubstrate through sputtering; 0<x<1.3, 0.7<y<2, x+y=2, and M<x>Ru<y>N2 is a cubic system or amorphous.

Description

technical field [0001] The present invention relates to catalyst material and its preparation method. Background technique [0002] In today's energy shortage, it is imperative to seek alternative energy, and hydrogen energy is the best alternative energy. Due to the concept of environmental protection, the use of hydrogen as fuel meets environmental protection expectations, and electrolysis of water is the easiest way to produce hydrogen and oxygen. Although the use of electrolyzed water to produce hydrogen has considerable advantages, it has a fatal disadvantage in the process of producing hydrogen in large quantities, that is, it consumes a considerable amount of energy and leads to inconsistent costs. Energy consumption is mostly related to overpotential, and overpotential is related to electrodes, electrolyte, and reaction products. In order to improve the efficiency of water electrolysis, electrodes play an important role. Reducing the activation energy and increasi...
