Nanotechnology – Energy and Environmental Technology

Nanotechnology – energy and environmental technology

In the past decades we started to struggle more and more often with the idea that the amount of resources on the Planet is not unlimited. That is why at this moment the energy technologies are aiming to be a part of the environmental technologies where we can produce durable and the nano-technology begin to play a considerable role in that industry :

  • Various nanomaterials can improve the efficiency of photovoltaic facilities;
  • Novel dye solar cells (“Grätzel cells”) with nanoscale semiconductor materials are currently under development; they mimic natural photosynthesis in green plants;
  • Plastics with CNTs as coatings on the rotor blades of wind turbines make these lighter and increase the energy yield;
  • Nano-technologically optimized lithium-ion batteries have an improved storage capacity as well as an increased lifespan and find use in electric vehicles for example;
  • Fuel cells with nanoscale ceramic materials for energy production are under development; their production requires less energy and resources;
  • Nanoporous membranes and filters with nanomaterials are used in water treatment and purification;
  • Nanoparticular iron compounds are used in groundwater remediation to remove chlorinated hydrocarbons;
  • The effectiveness of catalytic converters in vehicles can be increased by applying catalytically active precious metals in the nanoscale size range, and
  • Nanoporous particle filters are being developed to reduce emissions in motor vehicles.
