Two for one - cleaning water and generating energy

Abstract:
A fuel cell system that can generate electricity from organic compounds and clean up wastewater at the same time has been developed by scientists in China.

Yanbiao Liu from Shanghai Jiao Tong University and colleagues made a photocatalytic fuel cell comprising a TiO2-nanotube-array (TNA) anode and a platinum-based cathode. The cell uses light energy to degrade organic compounds in wastewater, generating electrons that pass through to the cathode, which converts the chemical energy into electrical energy.

'Organic compounds in wastewater are important sources of energy,' says Liu. Organic matter that amounts to a third of the global energy demand is lost in wastewater each year. 'Seeking sustainable approaches to recover energy from this waste and degrading it to a non-hazardous product is desirable.'
