From the Web: Light-powered device purifies air and generates clean energy

 

 

 

 

 

 

 

 

5.5 million people died prematurely because of air pollution back in 2013 – and half of those people lived in India or China. Air pollution continues to plague people around the world today, but now researchers from KU Leuven and the University of Antwerp have found a way to transform that dirty air into energy. They designed an air purifying device able to fit in a person’s hand that only needs light to work.

The groundbreaking device houses two small chambers divided by a membrane. In one chamber air is purified; in the other hydrogen gas is generated. Nanomaterials in the device act as catalysts to both break down pollution and produce the gas. Scientist Sammy Verbruggen of both institutions, who’s lead author on a study published recently about the device in ChemSusChem, said the hydrogen gas can be stored and used as fuel in the future.
