Problems solved by technology

TiO 2 The research on the application of photocatalytic materials mainly focuses on the four directions of purification of polluting gases, environmental sterilization, self-cleaning and anti-fog of building surfaces, and enhancement of heat transfer performance of air-conditioning refrigeration, and most of them focus on photocatalytic coatings, self-cleaning glass, functional Ceramics, photocatalytic concrete and other composite building materials exist, but there is no effective and feasible technical route for photocatalytic technology in mitigating the greenhouse effect
[0003] In addition, the existing green building technology also has many limitations, for example, the emission reduction effect is limited, and it is difficult to achieve the goal of zero emission; moreover, the design and construction are relatively complicated, the cost is high and cannot produce economic benefits, and the promotion is limited to a certain extent
These problems are not conducive to the green development of the construction industry

Abstract

A building emission reduction reactor based on a photoelectrocatalysis system comprises a photo-anode system, a dark cathode system and a direct-current power source, the photo-anode system is arranged on the outer surface of a building, and the dark cathode system is arranged on the inner surface of the building. An idle resource, namely a building wall body with a huge surface area, and renewable solar energy are fully utilized, and carbon dioxide is absorbed and oxygen is released by virtue of a photoelectrocatalysis reaction, so that the building emission is effectively controlled, and thegreenization level of a building is improved.
