2024年8月常州大学低碳清洁能源与安全高效燃烧科研团队孙运兰教授课题组2022级硕士研究生周海龙在Thermochimica Acta期刊发表了题为“Study on nano-sized boron particles modified by EMOF to enhance the combustion performance”的研究论文

本研究中，作者使用EMOF对nB进行改性，通过点火燃烧实验并结合各项表征，对EMOF的影响机制进行探索，其结论如下：

（1） EMOF可以降低nB的放热温度，扩大nB粉体的增重温度范围，增加nB的放热晗。

（2） EMOF可以显著提高nB的火焰强度和传播速度，降低点火延迟。

（3） EMOF分解可以破坏nB表面的氧化层，减少团聚。并且EMOF分解产生的CuO还可以催化nB的燃烧，以提升nB的燃烧效率。

英文摘要：

 Boron (B) powder has been considered a promising high-energy material due to its high calorific value. Nevertheless, the low combustion efficiency and the difficulty in ignition restrict its application. To solve the problems, in this study, an energetic metal-organic framework (EMOF) was used as a modifier for the nano-sized B powder, and its effect on the ignition and burning performance of B powder was examined. EMOF can significantly increase the heat release of B powder and lower its initial oxidation temperature. The best improvement is achieved with 10% EMOF contents in air, while the highest heat release is obtained with 25% EMOF contents in pure oxygen. Furthermore, EMOF can also reduce the ignition delay of B powder, enhance the flame intensity, and increase the flame propagation rate. This study offers new perspectives on modifying B powder with incorporating EMOF to develop multifunctional energetic particles with improved ignition and combustion characteristics.
