Abstract

The invention discloses an iodine-sulfur cycle hydrogen production method and system based on high-efficiency light energy utilization. The method comprises the steps: carrying out photocatalytic decomposition on an HI solution through solar illumination to obtain hydrogen, carrying out solid-liquid separation on the remaining material after photocatalytic decomposition to obtain elemental iodine,and carrying out a Bunsen reaction on the elemental iodine, sulfur dioxide and water to obtain HI and H2SO4, wherein HI prepared from Bunsen is used as a raw material for photocatalytic decomposition, H2SO4 generated by the Bunsen reaction is decomposed to generate SO2 under the condition of sunlight light heat gathering and heating, SO2 generated by decomposition of H2SO4 is used as a raw material for the Bunsen reaction, and the catalyst for photocatalytic decomposition is a catalyst based on methyl amino lead iodide. According to the method, solar energy can be used for replacing heat energy consumed in the circulation process, so that the reaction cost can be reduced to a great extent, and the method has a certain industrial application prospect.

Description

technical field [0001] The invention relates to the fields of efficient utilization of solar energy and iodine-sulfur cycle hydrogen production, in particular to a method and system for iodine-sulfur cycle hydrogen production based on high-efficiency light energy utilization. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] In recent years, the energy shortage and environmental problems caused by the endless consumption of fossil energy (coal, oil, and natural gas, etc.) have received close attention from all over the world. The most effective way to solve the above problems today is to find ideal energy sources to replace fossil fuels. As a secondary energy source, hydro...
