Abstract

The invention discloses a method for quantitatively analyzing the photocatalytic performance of silver bromide clusters. The method is based on quantum chemical density functional theory to characterize and measure the photocatalytic performance of silver bromide clusters. Through the structural research of silver bromide clusters , to determine its stable structure, and analyze the electronic structure, absorption spectrum, and positions of valence and conduction bands of silver bromide clusters according to the energy band theory, and finally determine its photocatalytic performance. Combined with relevant experimental research literature, a method for characterizing and measuring the photocatalytic performance of clusters is summarized. The method does not require any experiments, and can characterize the photocatalytic performance of silver bromide clusters only by using quantum chemical theoretical calculation; the method can be extended to the measurement and characterization of photocatalytic performance of other photocatalysts.

Description

technical field

[0001] The invention belongs to the technical field of chemistry and relates to a method for quantitatively analyzing the photocatalytic performance of silver bromide clusters. Background technique

[0002] Photocatalyst is a general term for chemical substances that can play a catalytic role under the excitation of photons. There are many methods for measuring its photocatalytic performance, such as: the photoactivity evaluation method of anatase coating film designed by Xu Qiuying of Harbin Institute of Technology, Japan Photocatalyst Association's "Photocatalyst Products Wet Decomposition Ability Determination Method", Taiwan Photocatalyst Industry Development Association "Photocatalyst Air Purification Efficiency Test Method" and so on. However, there are common problems such as complex experimental equipment, long time-consuming, and heavy interpretation of test results.

[0003] At present, the more commonly used evaluation method for photocatalytic p...
