Abstract
With the rapid development of nanotechnology, the application of functionalized nanoparticles in chemical reaction has attracted wide attention due to their unique physicochemical properties and high catalytic activity. Firstly, the definition, classification and synthesis methods of functionalized nanoparticles are introduced, with emphasis on surface modification techniques, which are essential for the catalytic properties of nanoparticles. In the theoretical foundation part, the basic concept of catalysis and the mechanism of catalytic reaction are described in detail, including acid-base catalysis and me tal catalysis. In addition, catalytic models of functionalized nanoparticles, such as single-point catalytic models and heterogeneous catalytic models, are explored, which are helpful in understanding how nanoparticles facilitate the conduct of chemical reactions. The applications of functionalized nanoparticles in environmental pollution control, energy conversion and storage, and chemical synthesis are demonstrated by examples. These application examples demonstrate the potential of functionalized nanoparticles in improving reaction efficiency, reducing energy consumption and reducing environmental pollution. In order to further improve the catalytic performance of functionalized nanoparticles, a series of optimization strategies are proposed. The relationship between morphology control and catalytic activity is discussed, which shows that the catalytic activity can be optimized by adjusting the shape and size of nanoparticles. The optimal design of surface functional groups is also the key to improve the catalytic performance. By changing the types and quantities of surface functional groups, the interaction between nanoparticles and reactants can be enhanced. In addition, strategies to improve the stability and reactivity of nanoparticles are discussed, which is essential to achieve long-term recycling of catalysts. Finally, the research progress of functionalized nanoparticles in catalysis is summarized, and the future development direction and application prospect of functionalized nanoparticles are prospected. With the further understanding of the catalytic mechanism of functionalized nanoparticles and the continuous advancement of material synthesis technology, it is expected that these nanomaterials will play a more important role in the chemical reaction process.
