Description
Technical Field
The invention belongs to the field of catalysts, and particularly relates to a preparation method of a supported Ir SAC @ Pt NPs @ MXene oxygen evolution catalyst with high activity and stability.
Background
The electrolysis of water to produce hydrogen (2H2O → O2+2H2) is a method for effectively obtaining clean energy and is receiving much attention in the scientific community. Wherein, the oxygen evolution reaction (2H2O → 4H + O2+4e-) is a 4-electron electrochemical reaction process formed by O-H bond breakage and O-O bond, the chemical kinetics of the process is slow, the efficiency is low (higher overpotential is shown), and therefore, the introduction of the catalyst effectively reduces the overpotential and accelerates the reaction process.
The supported noble metal catalyst is an important catalytic material, and plays an important role in industrial production because the supported noble metal catalyst can effectively reduce the production cost and retain excellent catalytic activity. Research shows that the distribution and size of the noble metal catalyst supported on the carrier directly affect the catalytic activity of the noble metal catalyst. For the traditional supported noble metal catalyst, the noble metal nano particles are not uniform in size, and the exposed crystal faces are different, so that the catalyst has different selectivity on reactants or products, and in the monatomic catalyst, the active sites are noble metal monatomics, so that the catalyst has a single structure and can show excellent catalytic activity. On the other hand, the single-atom catalyst has the maximum atom utilization rate because the noble metal achieves atomic dispersion, and has higher economic value compared with the traditional supported nano catalyst. The currently reported monatomic catalyst is relatively difficult to prepare, the mass fraction of the noble metal is more than 0.5%, if the loading amount of the noble metal is increased, noble metal nano-particles are difficult to avoid in the catalyst, and the monatomic or atomic cluster which is weakly combined with the carrier has high surface energy, is easy to migrate, agglomerate and sinter at high temperature, and needs to form effective interaction with the carrier to ensure the stability of the catalyst. Therefore, how to prepare a noble metal monatomic catalyst with high content and high stability and apply the noble metal monatomic catalyst to industrial production is a great challenge.
