Photocatalytic Degradation Analytical Service

Overview

Photocatalytic degradation uses irradiation and photocatalysts to generate reactive free radicals that break down organic pollutants into inorganic substances through addition, substitution, and electron transfer. Testing assesses a photocatalyst's effectiveness under specific conditions.

Key types of photocatalytic materials include:

1. Metal Oxides: Examples are TiO₂, Fe₂O₃, ZnO, and CuO, with TiO₂ being the most studied for its stability, high activity, and low cost.
2. Metal Sulfides: CdS and MoS₂ are representative materials.
3. Bismuth-Based Catalysts: These have unique layered structures, with internal electric fields promoting charge separation and enhancing activity.
4. Silver-Based Catalysts: Known for visible light responsiveness but prone to instability and photocorrosion, often improved through modifications like semiconductor composites.

Sample Requirement

• Powder Samples: Require 5–100 mg, depending on the experimental conditions. It is recommended to provide 2–3 times the required testing amount. For liquid, bulk, or other types of samples, specific arrangements need to be discussed.

• Note: Samples used in this test are non-recoverable.

Analytical Service Minimum order requirement: $250 per order. A $200 handling fee will be applied if order is below $250.

Please contact sales@msesupplies.com for additional information and instructions on our Analytical Services program. Confirmation of the sample(s) requirements, SDS sheets and additional information is needed prior to processing the Analytical Service order.
