Photocatalyst composite structure and preparation method thereof

Abstract

The present invention provides a photocatalyst composite structure and a preparation method thereof. The photocatalyst composite structure has backbone-branch structural feature; the graphite type carbon nitride (g-C3N4) is the backbone, and carbon nanotubes(CNTs) grown in situ on the backbone chemical through vapor deposition (CVD) are the branches; and the nano photocatalyst coats on the entire backbone-branch complex structure surface. The invention has the advantages that the photocatalyst composite structure can degrade organic contaminants and realize photocatalytic water decomposition for hydrogen production under ultraviolet and visible light; in addition, the backbone-branch composite structure has large specific surface area, and can fully contact with organic pollutants and electrolyte solution to improve the photocatalytic efficiency.

AI Technical Summary

Benefits of technology

This patented technology describes an improved catalyst system called this compound's specialized structures made up from tiny particles or small tubular segments attached together at their ends. These smaller parts create larger areas where certain molecules like oxygen have enough space available for them to attach themselves onto these surfaces. By combining different types of materials into one material, it provides more effective ways to remove harmful contaminant species such as pesticides, bacteria, dirt, grease, etc., while also allowing other components within the matrix to absorb sunlight effectively without losing effectiveness over longer periods due to reduced activity levels caused by long exposure times. Overall, this innovative design enhance the performance and durability of various industrial processes involving decomposition reactions.

Problems solved by technology

Technologies for creating efficient catalyst systems containing both oxygen atoms and carboxyl radicals for decompositring harmful chemical species from contaminants include combining different types of photosensitive materials together to enhance their activity towards decomposition of harmful molecules without reducing their effectiveness over time. Additionally, modifying the crystal size distribution of various components within each type helps increase the effective area of exposed surfaces and increases the amount of active sites per unit volume. These modifications help achieve better optically excited charge transfer processes between the charges and reduced dark current scatterings during photochemistry.
