“…It can be seen that the pristine Ti-MOF displays the strong emission peak at 430 nm as similar to the previous report. [55] M 2+ ions coordinated MOFs exhibits less PL emission intensity than the pristine Ti-MOF, demonstrating the rapid charge carrier separation through the coordinated M 2+ ions. It is noted from the PL spectra that the emission Small 2020, 16,1902990 intensities are decreased with respect to the different M 2+ ions coordination.…”

Design and development of efficient photocatalysts for H2 production from water and sunlight have gained significant attention as the solar assisted approach is considered to be a promising approach for the generation of clean fuel. However, the poor charge carrier separation and light harvesting ability of existing photocatalysts limits the efficiency of photoconversion of water. In this work, the synthesis of transition metal ions (M2+ = Co2+, Cu2+, and Ni2+) coordinated with Ti‐metal organic frameworks (Ti‐MOFs) through a simple post‐synthetic coordination method for efficient solar light‐driven H2 production is reported. Notably, coordination of M2+ ions with Ti‐MOF significantly improves the optical absorption by d–d transitions and the multimetal sites facilitate the fast charge carrier separation, thereby enhancing the solar light‐driven H2 production activity. Very interestingly, the rate of solar light‐driven H2 production is varied with respect to different metal ions coordination due to the position of d–d bands absorption in the solar spectrum, and the complexing tendency of M2+ ions with sacrificial electron donors. A maximum solar H2 production rate of 1583.55 µmol h−1 g−1 is achieved with a Cu2+ coordinated Ti‐MOF, which is ≈13 fold higher than that of the pristine Ti‐MOF.

“…According to the types of chemical reactions, nanoenergetic composite films can be divided into two categories: one is metal/oxide nanoenergetic composite films that can undergo aluminothermic reactions, such as Al/CuO [ 3 , 4 , 6 ], Al/MoO 3 [ 7 , 8 ], Al/Fe 2 O 3 [ 9 , 10 ] , and Al/NiO [ 11 , 12 ], etc. The other is metal/metal nanoenergetic composite films, such as Al/Ni [ 13 , 14 , 15 ], Al/Ti [ 16 , 17 ], and B/Ti [ 18 , 19 ], which can be alloyed. The volume energy density of nano Al/CuO energetic composite film is even higher than that of conventional explosive cyclotrimethyltrinitroamine (RDX).…”

Exploring the Interfacial Reaction of Nano Al/CuO Energetic Films through Thermal Analysis and Ab Initio Molecular Dynamics Simulation

The effect of the interface layer on energy release in nanoenergetic composite films is important and challenging for the utilization of energy. Nano Al/CuO composite films with different modulation periods were prepared by magnetron sputtering and tested by differential scanning calorimetry. With the increase in the modulation period of the nano Al/CuO energetic composite films, the interface layer contained in the energetic composite film decreased meaningfully, increasing the total heat release meaningfully. Ab initio molecular dynamics (AIMD) simulation were carried out to study the preparation process changes and related properties of the nano Al/CuO energetic composite films under different configurations at 400 K. The results showed that the diffusion of oxygen atoms first occurred at the upper and lower interfaces of CuO and Al, forming AlOx and CuxAlyOz. The two-modulation-period structure changed more obviously than the one-modulation-period structure, and the reaction was faster. The propagation rate and reaction duration of the front end of the diffusion reaction fronts at the upper and lower interfaces were different. The Helmholtz free energy loss of the nano Al/CuO composite films with a two-modulation-period configuration was large, and the number of interfacial layers had a great influence on the Helmholtz free energy, which was consistent with the results of the thermal analysis. Current molecular dynamics studies may provide new insights into the nature and characteristics of fast thermite reactions in atomic detail.

Reactive multilayer films (RMFs) are a type of a thermite nanoenergetic multilayer film, which can be potentially applied to an exploding foil flyer generator (EFFG). Herein, Al/Ni RMFs with a bilayer thickness of 500 nm are integrated into an exploding foil layer by a magnetron sputtering method. The effects of interface layer on the properties of the EFFG are systematically investigated in terms of the electrical behavior and flyer velocity. The interface layer is controlled by annealing, whose structure and chemical composition are confirmed by X‐ray diffraction and transmission electron microscopy. The periodic multilayer structure can be clearly visible, and the thickness of interface layer increases with increasing annealing temperatures from room temperature to 573 K. The EFFG integrating as‐deposited Al/Ni RMFs exhibits improved exploding properties with a short exploding time, violent explosion region, and high flyer velocity phenomenon in comparison with generator at 573 K. Overall, the EFFGs integrated Al/Ni RMFs with larger interface layers can decrease the electrical plasma performances, which are significant for investigating the applicability in various engineering fields.
