Article Synopsis
- The study uses density functional theory (DFT) to examine how low oxygen vacancy formation energy affects the catalytic performance of chemical looping dry reforming of methane (CL-DRM) when metal ions Zn and Nd are co-substituted on CeO(111) surfaces.
- Results show that the co-substituted surfaces have a very low oxygen vacancy formation energy (-2.05 eV), enhancing the CH conversion process compared to pristine surfaces, with the rate-limiting step being the dehydrogenation of CH.
- However, while the co-substituted surfaces promote better reaction performance, high energy is required for syngas desorption and CO selectivity is reduced, indicating a balance is needed to prevent excessive
In order to improve the mechanical properties and thermodynamic stability of the long needle-like raw material Nitroguanidine (NQ), it was pulverized by a mechanical pulverization method and dried by a spray drying method, and three ultrafine NQ samples with different aspect ratios (2.26, 1.87, and 1.

The thermal behaviors and chemical kinetic parameters of the above two propellants and their mixtures with water were analyzed by using a CALVET heat flux calorimeter, C80. The thermal decomposition mechanisms of these two propellants with water were conjectured based on the tests.
