Embodiment 1

[0024] Embodiment 1: preparation embodiment

[0025] Take 0.6g Vulcan XC-72 toner, 0.1g of Ac 2 o 3 powder, 10.25 mL of HO 2 PtCl 6 (0.1mol / L) solution and 17.04mL of NiSO 4 (0.1mol / L) solution was mixed and added to 80mL deionized water, ultrasonicated for 30min to disperse evenly, then under stirring, after adjusting the pH value to 8-9 with 1mol / L NaOH solution, slowly add excess 2.0mg / mL NaBH 4 Solution, continue to stir for 3h. Wash with ultrapure water until Cl-free - Afterwards, vacuum-dried at 60°C for 4 h to obtain Pt-Ni-Ac 2 o 3 / C Catalyst.

Abstract

The invention belongs to the technical field of catalysts, and relates to a platinum-based catalyst containing an actinide elementary substance or compound. The platinum-based catalyst comprises a catalytic active substance and a catalytic auxiliary substance, the catalytic active substance comprises metal platinum, the catalytic auxiliary substance comprises a cocatalyst, and the cocatalyst comprises one or more of simple substances or compounds of actinide or protactinium. The platinum-based catalyst containing the actinide simple substance or compound has better catalytic performance and stability.

Description

technical field [0001] The invention belongs to the technical field of catalysts and relates to a platinum-based catalyst containing actinide elements or compounds. Background technique [0002] Catalyst materials and catalytic technology are one of the basic and key materials and technologies for the development of today's chemical industry. In modern industry, the output value generated by the use of catalytic technology has accounted for about 30% of the total output value of the national economy. [0003] The outer electron configuration of noble metal Pt is 5d 8 6s 2 , followed by a total of 8 d electrons in the outer layer, and the orbitals are not filled. And because the energy level contains unpaired electrons, Pt can exhibit strong ferromagnetism or paramagnetism in physical properties; and in the process of chemical adsorption, these d electrons of Pt can interact with the p electrons in the adsorbate. Or s-electron pairing, chemical adsorption occurs, and inte...
