Nanomaterials offer new possibilities for cleaner, more efficient energy technologies. At the NN Group, we design and synthesise advanced nanomaterials for use in energy conversion, storage, and harvesting — with a strong emphasis on sustainability and multifunctionality.

Our research includes the development of nanocrystals and nanocomposites for electrochemical water splitting, a promising route for green hydrogen production. We focus on scalable, low-energy synthesis methods to obtain nanomaterials with controlled morphology and surface properties, optimised for catalytic performance.

We also work on magneto- and thermoelectric nanocomposites that convert heat into electricity through wireless power transfer. In the HYPE-POWER project, we develop nanoheterostructures that combine hyperthermia and thermoelectric effects to enable contactless charging or power generation. These materials have potential uses in powering implantable medical devices or improving energy efficiency in autonomous systems.

Another key line of research is the upcycling of organic waste to produce carbon-based inks for printable electronics and environmental sensing. This circular approach supports the development of sustainable nanomaterials that can be used in smart textiles or biodegradable sensors.

Our work bridges materials chemistry, energy science, and green technology. By combining novel synthesis strategies with advanced characterisation, we aim to understand how nanoscale structure affects energy-related properties such as conductivity, catalytic activity, and thermal response.

The NN Group is committed to developing energy nanomaterials that are not only functional, but also scalable, cost-effective and environmentally responsible. Through both fundamental studies and applied projects, we contribute to shaping the future of sustainable energy technologies.
