Organic-inorganic Hybrid Material Chemistry Laboratory
Our laboratory studies the development of organic-inorganic hybrid nanomaterials (one of the most promising families of functional materials) and also high-throughput and high-efficiency synthetic methods for their synthesis. Our applied research is aimed at the development of applications of these materials in materials as catalysts, catalyst supports, photocatalysts, absorbents, storage and slow release materials, nano-ink for forgery prevention, cosmetics, and electrode materials for secondary batteries; and in processes such as drug and gene delivery. |
