Abstract

The invention belongs to the technical field of catalyst preparation and discloses a cellulose acetate electrostatic-spun film loaded AgCl-Ag catalyst and preparation method and application thereof. The preparation method comprises the steps of preparing cellulose acetate into electrostatic spinning solution by using a solvent, then preparing an electrostatic-spun film in electrostatic spinning equipment, enabling an AgNO3 solution and a NaCl solution to be diffused on the electrostatic-spun film through a double-diffusion method to grow AgCl crystals in situ, and finally obtaining the cellulose acetate electrostatic-spun film loaded AgCl-Ag catalyst through sunlight irradiation. Since the catalyst disclosed by the invention uses cellulose acetate as a substrate, the catalytic efficiency is high, the raw materials are cheap and easy to obtain, and the catalyst is convenient to use and simple to recover and has a good actual application value.

Description

technical field [0001] The invention belongs to the technical field of catalyst preparation, and in particular relates to an AgCl-Ag catalyst loaded on a cellulose acetate electrospun membrane and its preparation and application. Background technique [0002] With the increasing energy problems, how to more effectively and fully utilize green energy such as biomass energy and solar energy to replace traditional petrochemical energy has received widespread attention from the society. [0003] As the most widely existing resource in nature, cellulose is a renewable, green and environmentally friendly natural polymer material. Cellulose acetate, that is, cellulose acetate, was first prepared in 1865. It is an industrialized product with good processing properties and is easy to form film and silk. Cellulose acetate is used in photography as a base for film negatives and also as a rayon. Silver chloride-silver is a semiconductor material. In 2008, Huang et al. used silver chlo...
