Research progress of EMOFs-based burning rate catalysts for solid propellants

Abstract

Energetic Metal Organic Frameworks (EMOFs) have been a hotspot of research on solid propellants in recent years. In this paper, research on the application of EMOFs-based burning rate catalysts in solid propellants was reviewed and the development trend of these catalysts was explored. The catalysts analyzed included monometallic organic frameworks-based energetic burning rate catalysts, bimetallic multifunctional energetic burning rate catalysts, carbon-supported EMOFs burning rate catalysts, and catalysts that can be used in conjunction with EMOFs. The review suggest that monometallic organic frameworks-based burning rate catalysts have relatively simple catalytic effects, and adding metal salts can improve their catalytic effect. Bimetallic multifunctional energetic burning rate catalysts have excellent catalytic performance and the potential for broad application. The investigation of carbon-supported EMOFs burning rate catalysts is still at a preliminary stage, but their preparation and application have become a research focus in the burning rate catalyst field. The application of catalysts that can be compounded with EMOFs should be promoted. Finally, environmental protection, high energy and low sensitivity, nanometerization, multifunctional compounding and solvent-free are proposed as key directions of future research. This study aims to provide a reference for the application of energetic organic burning rate catalysts in solid propellants.

“…2–5 Moreover, they are widely used as catalysts for propellants and pyrotechnic formulations. 6 Furthermore, energetic metal complexes as precursors produce hybrid nanocomposites and hold great promise for future research in nano-thermite technology. 7–9 These diverse applications of energetic metal complexes not only highlight their importance but also introduce new avenues for fundamental research.…”

Effects of Nanocomposite Derivatives of Ni–Fe, Ni–Co, Ni–Co–Fe Prussian Blue Analogues on the Thermal Decomposition Performance of Nitrocellulose

“…There is currently a dearth of study on the catalytic behavior and catalytic breakdown processes of other energetic molecules, with the majority of studies on MOF-based combustion catalysts concentrating on their catalytic effects on ammonium perchlorate propellants . This work offers a novel solution in response: PB analogues were created using Ni–Fe, Ni–Co, and Ni–Fe–Co metals, and the resulting compounds were then incorporated into NC as nanocatalysts.…”

We conducted a thorough investigation into how these loaded nanocomposite metal oxides affected the thermal deterioration of NC, and we produced valuable data to direct future application-focused research.…”

“…Metal, metal oxide and metal composite oxide catalysts are earlier used and thoroughly studied burning rate catalysts, which have good catalytic effects on most solid propellants. Current research on such catalysts mainly focuses on the preparation of nanoscale catalysts with exceptional catalytic performance from effective metals or metal oxides [ 4 , 5 , 6 , 7 ]. However, nano-sized catalysts have two shortcomings.…”
