Abstract

The invention discloses a method for preparing a composite film photoelectrode, and the method comprises the following steps of: preparing an electrode matrix: taking platinum-plated titanium conductive glass as an electrode substrate, soaking the electrode substrate in a hydrogen peroxide solution, washing the electrode substrate with water, and performing ultrasonic treatment to form a film electrode layer; then, putting the film electrode layer into a sodium hydroxide solution for ultrasonic treatment, repeatedly carrying out ultrasonic cleaning by using deionized water, and then, drying; finally, electropolishing and ultrasonically washing with water in a sodium hypochlorite electrolytic cell to prepare the electrode matrix, and drying the electrode matrix; and pretreating the electrode matrix: adding graphene into a mixed solution of sodium carboxymethylcellulose and styrene to obtain a coating solution; performing coating solution spin-coating on the electrode matrix, and performing annealing treatment to obtain an electrode preform; and preparing a composite film photoelectrode: preparing an LDH electrode from the electrode preform by using an electro-deposition method, placing the prepared LDH electrode in a muffle furnace, and calcining and air-cooling to prepare an MMO electrode; and preparing an MMO photoelectrode covered by a lead dioxide film by using an electrodeposition method, washing with water, and drying.

Description

technical field [0001] The invention belongs to the technical field of photoelectrodes, and relates to a method for preparing composite film photoelectrodes. Background technique [0002] Serious environmental problems such as global warming and acid rain, as well as the limited global reserves of fossil fuels, seriously restrict the sustainable development of the global economy. In order to reduce fossil fuel consumption and solve related environmental problems, it is urgent to increase solar energy, hydrogen energy, etc. The utilization rate of clean energy, photocatalytic water splitting hydrogen production can effectively use sunlight to split water to generate clean energy hydrogen, which is a new technology that can solve both energy crisis and environmental pollution problems. Photoelectrodes are the key to this technology. Therefore, it is very important to find suitable photoelectrocatalytic electrode materials and improve photoelectrode preparation methods. [000...
