Interaction Between Prussian Blue Ultrathin Nanosheet and Ammonium Perchlorate for Highly Efficient Thermal Decomposition

Advanced Functional Materials (2023)

Peng Zhou Zhuoqun Ren Xiaolin Tang Zeyu Zheng Kuan Zhang

Abstract Catalytic stability is the prerequisite for the catalyst to achieve high catalytic efficiency. This study finds a new path that Prussian Blue (PB) ultrathin nanosheet assembly material (PB‐NSa) is designed and used to reach efficient catalysis through continuous interaction with ammonium perchlorate (AP, component to be catalyzed). Based on the strong oxidation environment provided by AP, the decomposition of PB occurs in advance, the product Fe 2 O 3 accelerates the decomposition of AP that can release a large amount of gas, then reacts on Fe 2 O 3 and disperses it near the undecomposed AP, finally realizing continuous and efficient catalysis. The results show that under the catalysis of PB‐N, “deactivation” stage of AP thermal decomposition disappears, showing two consecutive exothermic stages, high temperature decomposition peak of AP is reduced to 341.1 °C, the reduction range is 73.1 °C. Combining kinetic calculation and TG‐IR test, it is found that PB‐NSa can keep excellent catalytic stability, which depends on its special structure and interaction with AP. This research provides a design idea for the material to achieve catalytic stability, which will greatly promote its rapid industrialization.

Oriented Assembled Prussian Blue Analogue Framework for Confined Catalytic Decomposition of Ammonium Perchlorate

Small (2023)

Peng Zhou Xiaolin Tang Zhuoqun Ren Zeyu Zheng Kuan Zhang

The design of highly dispersed active sites of hollow materials and unique contact behavior with the components to be catalyzed provide infinite possibilities for exploring the limits of catalyst capacity. In this study, the synthesis strategy of highly open 3-dimensional frame structure Prussian blue analogues (CoFe-PBA) was explored through structure self-transformation, which was jointly guided by template mediated epitaxial growth, restricted assembly and directional assembly. Additionally, good application prospect of CoFe-PBA as combustion catalyst was discussed. The results show that unexpected thermal decomposition behavior can be achieved by limiting AP(ammonium perchlorate) to the framework of CoFe-PBA. The high temperature decomposition stage of AP can be advanced to 283.6 °C and the weight loss rate can reach 390.03% min-1 . In-situ monitoring shows that CoFe-PBA can accelerate the formation of NO and NO2 . The calculation of reaction kinetics proved that catalytic process was realized by increasing the nucleation factor. On this basis, the catalytic mechanism of CoFe-PBA on the thermal decomposition of AP was discussed, and the possible interaction process between AP and CoFe-PBA during heating was proposed. At the same time, another interesting functional behavior to prevent AP from caking was discussed.

In Situ Cutting of Ammonium Perchlorate Particles by Co‐Bipy “scalpel” for High Efficiency Thermal Decomposition

Advanced Science (2022)

Peng Zhou Siwei Zhang Zhuoqun Ren Xiaolin Tang Kuan Zhang

Abstract Burning rate of solid propellants can be effectively improved by adding catalysts and using smaller size ammonium perchlorate (AP). Although few reports, the exploration of changing the size of AP primary particles by catalysts is of great significance for improving combustion performance. Here, taking Co‐bipy as an example, the potential advantages of such materials as AP decomposition catalysts are reported. Due to the existence of NO 3 − combined with oxygen rich environment provided by AP, the structural self‐transformation from micronrods to nanoparticles can be quickly realized during the heating process. More importantly, when Co‐bipy decomposes, it can play the role of “scalpel” and in situ cut AP particles. Results show that high‐temperature decomposition of Co‐bipy/AP occurs at 305.8 °C, which is 137.5 °C lower than that of pure AP. Catalytic mechanism is discussed by in situ IR and TG‐IR, CoO can effectively increase the content of reactive oxygen species and weaken the N–H bond, realizing the rapid oxidation of NH 3 . Eventually, the behavior of Co‐bipy cutting AP particles is tested. This interesting catalyst structure self‐transformation behavior can not only realize the influence on AP, but also perform a positive function in the combustion process of solid propellants, such as opening the adhesive AP interface.

Hierarchical MOFs with Good Catalytic Properties and Structural Stability in Oxygen‐Rich and High‐Temperature Environments

Small (2024)

Zeyu Zheng Peng Zhou Xiaolin Tang Qihui Zeng Shengping Yi

Abstract Metal‐organic framework materials are ideal materials characterized by open frameworks, adjustable components, and high catalytic activity. They are extensively utilized for catalysis. Due to decomposition and structural collapse under high temperatures and an oxygen‐rich environment, the potential of thermal catalysis is greatly limited. In this research, Co‐rich hollow spheres (Co‐HSs) with a gradient composition are designed and synthesized to investigate their thermal catalytic properties in the ammonium perchlorate（AP）system. The results demonstrate that Co‐HSs@AP exhibits good thermal catalytic activity and a high‐temperature decomposition of 292.5 °C, which is 121.6 °C lower than pure AP. The hierarchical structure confers structural stability during the thermal decomposition process. Thermogravimetry‐infrared indicates that the inclusion of Co‐HSs successfully boosts the level of reactive oxygen species and achieves thorough oxidation of NH 3 . Based on the above phenomenon, macro dynamics calculations are carried out. The results show that Co‐HSs can promote the circulation of lattice oxygen and reactive oxygen species and the multidimensional diffusion of NH 3 in an oxygen‐rich environment. This material has significant potential for application in the fields of thermal catalysis and ammonia oxidation.
