光触媒分散液、光触媒複合材料および光触媒装置
Document Type and Number:
Japanese Patent JP6989421
Kind Code:
B2
Abstract:
To provide a photocatalyst dispersion liquid that is stably dispersed and has high antibacterial action, a highly active photocatalyst composite material and a photocatalyst device.MEANS FOR SOLVING THE PROBLEM: A dispersion liquid has water, a main catalyst particle having a negative zeta potential in water at 20°C and pH 6, and a cocatalyst particle having a positive zeta potential. An average diameter of the main catalyst particles is smaller than that of the cocatalyst particles.SELECTED DRAWING: Figure 1
