Energy & Catalyst Applications

Nanomaterials stand at the forefront of innovation, offering unparalleled versatility in revolutionizing energy and catalysis applications. At our laboratory, we specialize in the synthesis and application of nanoparticles, harnessing their unique optical, electronic, and chemical properties for transformative advancements.

From pioneering green hydrogen production through electrolysis techniques to pushing the boundaries of fuel cell technology, our research endeavors encompass a broad spectrum. We are dedicated to developing cutting-edge electrocatalysts for fuel cells and advancing the synthesis of efficient photocatalysts for sustainable energy conversion.

In tandem with our commitment to green energy solutions, we explore the synergistic integration of machine learning algorithms for the discovery of novel materials with unprecedented performance. By leveraging our expertise in nanocrystal design and assembly, we continue to push the boundaries of possibility, striving to optimize the composition and structure of nanomaterials for targeted applications.

Our recent breakthroughs include the development of highly durable and active nanocatalysts for photochemical and electrochemical reactions, such as the synthesis of single-atom Cu/TiO2 photocatalysts, multimetal-doped Ir and Ru-based oxide nanoparticles, and PtFe nanoparticles integrated with N-doped carbon shells.
