Materials referred to as "nanomaterials" generally fall into two categories: fullerenes, and inorganic nanoparticles. See also Nanomaterials in List of nanotechnology topics

information obtain from http://en.wikipedia.org/wiki/Nanomaterials#Materials_used_in_nanotechnology

Nanomaterials that generate heat would be
1.Graphite
2.Graphene
3.Carbon nanotubes
4.Glassy carbon
The nanomaterials mentioned above are fullerenes and "are a class of allotropes of carbon" link to these allotropes of carbon
http://en.wikipedia.org/wiki/Allotropes_of_carbon

1.Nanoparticle photovoltaic cell
2.Magnetic nanoparticles
3.Quantum dot
4.Silicon
5.Transparent materials
The nanomaterials mentioned above are Nanoparticles
link to these nanoparticles http://en.wikipedia.org/wiki/Nanoparticle

They can generate heat up to 400 degrees Fahrenheit

also these links are very interesting

The article on DLR alternative compounds for thermoelectric generators was interesting.

1. Scientist at DLR are searching for new ways of producing electricity from wasted process heat.
2. Can a solid body be caused to release electrical energy simply by heating it on one side?
3. A thermoelectric module is mounted on a block of metal. Heat differential creates a current. The thermal response is made possible in solid state physic by the Peltier effect.
4. The electrical current is made to pull along an accompanying heat flow, with such force that it surpasses even large temperature differences, much like water being pumped uphill.
5. The flow of heat through the thermoelectric material create an electric current. Efficiency levels are very low. There are no moving mechanical parts.
6. Wasted heat is becoming a viable source of electricity.
7. The only thermoelectric materials are special tellurium compounds. Favoured materials include chalcogenides, skutterudites, silicides, and clathrates.
