Flame Spray Pyrolysis of photocatalyst on powdered biochar for the degradation of organic contaminants

A flame spray pyrolysis process that improves photocatalytic efficiency.

Background

The flame spray pyrolysis (FSP) with powder substrate holder and collection system is successful in fabricating a photocatalyst and decorating it onto the surface of carbonaceous support material. Photocatalytic efficiency was improved significantly, into the visible light range. This method combined physical adsorption and photocatalytic degradation mechanisms that removed a model organic contaminant from the aqueous solution. In doing so, progress to develop a facile, efficient, sustainable water treatment method has been made. 

Technology Overview

 The Flame spray pyrolysis process includes a powder substrate holder and collection system which fabricates a photocatalyst and decorates it onto the surface of the carbonaceous support material. Photocatalytic efficiency was improved significantly into the visible light range. 

Benefits

 ‑ Improved photocatalytic efficiency into visible light range 

Applications

This technology can be used to fabricate metal-oxide nano-materials while distributing onto powdered carbonaceous substrate. Photocatalyst-carbonaceous material is intended to be used to remove organic pollutants from aqueous solutions. 

Opportunity

 Modification of photocatalysts by decorating onto carbon material for efficient use in the visible light region. This process set up allows for even distribution of modified nano-photocatalysts onto powdered material.
