Research Themes +
Energy Technologies Area (ETA) researchers are continually building on the strong scientific foundation we have developed over the past 50 years. We address the world’s most pressing climate challenges by bringing to market energy-efficient innovations across the buildings, transportation, and industrial sectors. ETA is at the forefront of developing better batteries for electric vehicles; improving the country's aging electrical grid and innovating distributed energy and storage solutions; developing grid-interactive, efficient buildings; and providing the most comprehensive market and data analysis worldwide for renewable technologies like wind and solar.
Strategic Initiatives +
The Energy Technologies Area (ETA) Strategic Plan is the guiding force for our research and development for the next ten years. It clearly charts a path toward clean-energy solutions and focuses on five detailed Strategic Initiatives. The Plan provides an in-depth look at how ETA is accelerating research to provide affordable, clean energy to all while accomplishing deep, economy-wide decarbonization, looking to avoid a rise in global average temperature while simultaneously developing solutions to increase humanity's resilience to extreme weather volatility.

Abstract

Composite carbon–platinum thin-films of nano-crystalline graphitic carbon decorated with uniformly-dispersed 2–4 nm Pt nano-particles have been synthesized from a solid organic precursor by a one-step microwave plasma chemical vapor deposition (MPCVD). The fast Ar-plasma discharge and the presence of microwave radiation accelerate the formation of sites suitable for in situ heterogeneous nucleation, and consequently, the fine dispersion of metal in the carbonaceous matrix. The electrochemical response of the 2 μm C/Pt thin-film electrode displays electrochemical activity, which is attributed to the high ca. 18 m²/g effective surface area of Pt nano-particles.
