Nanoconcepts and Simulations

Nanoconcepts represent self-contained instructional materials focusing on the key ideas in nanoscale science and engineering (NSE) and their applications. Each Nanoconcept contains a general user introduction, main concept, notes, images and/or simulations. A usage guide and connections to general science concepts is also provided to aid integration into the classroom.

Photocatalytic Degradation of Methylene Blue by Titanium Dioxide - Interactive Computational Animations on Nanomaterials

 

When titanium dioxide is illuminated with UV light, its electrons are excited to higher energy levels where they can interact with organic chemicals such as methylene blue. The interaction degrades the methylene blye molecules causing its blue color to disappear. This process is called “photocatalysis” and has applications in medicine, energy, and environment. This animation introduces the concept of photocatalysis and step involved in the process.

OVERVIEW:

When titanium dioxide is illuminated with UV light, its electrons are excited to higher energy levels where they can interact with organic chemicals such as methylene blue. The interaction degrades the methylene blye molecules causing its blue color to disappear. This process is called “photocatalysis” and has applications in medicine, energy, and environment. This animation introduces the concept of photocatalysis and step involved in the process.

This animation is appropriate for teaching AP chemistry. It teaches reaction rates and kinetics in detail and contains interesting graphing simulation where you could study if whether the reaction was 1st order or 2nd order with respect to the [MB], [catalyst], or pH ([H+]).
