Abstract
With the rapid development of nanotechnology, the application of nanomaterials in the field of catalyst carriers has attracted widespread attention. In the section on the basic characteristics of nanomaterials, the article elaborates in detail on the definition, characteristics, and key features such as surface effects, volume effects, and quantum size effects of nanomaterials. These characteristics enable nanomaterials to exhibit excellent performance in catalytic reactions. The third chapter of the article delves into the relationship between nanomaterials and catalytic reactions, analyzing the effects of surface activity, pore structure, stability, and regeneration ability of nanomaterials on catalytic performance. These factors collectively determine the efficiency and selectivity of nanomaterials as catalyst carriers. Chapter 4 is the core of this article, which systematically discusses the performance optimization strategies of nanomaterial catalyst carriers. Including surface modification, composite structure design, size and morphology control, and loading technology. The introduction of surface active sites and modification of surface functional groups can improve the activity and selectivity of catalysts. The preparation of core-shell structures and multi-component composite materials provides a new design concept for catalyst supports. The exploration of size effects and morphology control strategies provides guidance for the synthesis of nanomaterials. The application of loading techniques such as impregnation and in-situ growth further improves the dispersion and utilization of catalysts. In Chapter 5, the article discusses the challenges faced by nanomaterial catalyst carriers, including large-scale production issues, environmental and health impacts, and looks forward to the future development direction of nanomaterial catalyst carriers. The application prospects of nanomaterials in the field of catalysis and their importance in achieving sustainable development goals were pointed out. This article provides a theoretical basis and practical guidance for the application of nanomaterials in catalyst carriers through systematic analysis and research, which is of great significance for promoting the research and application of nanomaterials in the field of catalysis.
