Conductive Y zeolite molecular sieve as well as preparation method and application thereof

Abstract

The invention discloses a conductive Y zeolite molecular sieve as well as a preparation method and application thereof, and belongs to the technical field of preparation of inorganic molecular sieve catalysts. The general chemical formula of the conductive Y zeolite molecular sieve provided by the invention is Na2O. AlyR < 2-y > O < 3 >. WSiO < 2 >. XH2O, wherein 0 < y < 2, w is 20-10, and x is 1-3; r is selected from one of chromium ions and zirconium ions. According to the conductive Y zeolite molecular sieve provided by the invention, chromium ions or zirconium ions are introduced into a Y zeolite framework and replace part of Al ions, so that the framework of the Y zeolite molecular sieve can be polarized, and the conductivity of the zeolite molecular sieve is greatly improved; the morphology structure and the three-dimensional pore channel structure of the zeolite molecular sieve can be reserved, the pore size is enlarged, and the material transmission efficiency and the reaction activity are enhanced; meanwhile, the crystal structure of the Y zeolite molecular sieve can be reserved, the crystallinity can be obviously improved, the structural stability and reaction activity of the Y zeolite molecular sieve are further improved, the application bottleneck of the zeolite molecular sieve in the electrochemical field is broken through, and the Y zeolite molecular sieve has wide application prospects in electrochemical catalytic reactions.
