“…[ 46 ] The peak observed at 12.22° in the Co‐MOF, 12.14° in the Fe‐MOF, and 12.14° in the TFC‐MOF corresponds to the characteristic diffraction peak of H 3 BTC, respectively. [ 47 ] This indicates the existence of H 3 BTC in the electrocatalysts, which is important for the formation reactions. The crystallography feature of the TFC‐MOF is confirmed by the comparison with the Fe‐MOF and the Co‐MOF.…”

It is urgent to design a low‐cost electrocatalyst with high activity to enhance the efficiency of oxygen evolution reaction (OER), which is limited by the slow four‐electron transfer kinetics process. Nevertheless, traditional synthetic methods, including calcination and solvothermal, of the electrocatalysts are high‐cost, low‐yield, and energy‐hogging, which limits their industrial application. Herein, an ambient fast synthetic method is developed to prepare terrace‐like Fe/Co bimetal‐organic framework (TFC‐MOF) electrocatalyst materials in gram scale in 1 h. The method in this paper is designable based on coordination chemistry. Fe and Co ions can coordinate with the carboxyl groups on benzene‐1,3,5‐tricarboxylic acid (H3BTC) to form a 2D‐MOF structure. Structural characterizations, including SEM, TEM, and XRD are conducted to verify that the TFC‐MOF is a terrace‐like layered structure with uniform‐sized mesoporous, which reduces the adsorption steric hindrance and facilitates the mass and electron transfer efficiency of OER. The TFC‐MOF shows low overpotential, 255 mV at a current density of 10 mA cm−2, and a low Tafel slope of 49.9 mV dec−1, in an alkaline solution. This work provides a planar coordination strategy to synthesize 2D‐MOF OER electrocatalyst on a large scale with low cost and low energy consumption, which will promote its practical OER applications.

“…Previously, our group reported a gas–solid two-phase flow (GSF) technique as an alternative method to conventional mechanochemical synthesis. − The technology is based on the principles of the hydrodynamic theory, in which reactant particles are accelerated by a high-speed carrier gas to 300 m·s –1 or higher, and particles convert enormous mechanical energy into activation energy required to overcome the chemical reaction by hitting the target or colliding with it, thus achieving an efficient chemical reaction. In this process, the expansion of the compressed gas absorbs heat, causing the ambient temperature to drop significantly and enabling the reaction to occur at low temperatures.…”

In this work, we report a novel spiral gas−solid two-phase flow (S-GSF) technique for the continuous mechanochemical synthesis of N-acylhydrazone derivatives. The synthesis of (E)-N′-(4-nitrobenzylidene)benzoylhydrazide (compound 1) was used as a model reaction to demonstrate the feasibility of this approach. The prepared products were characterized by Fourier transform infrared spectroscopy, nuclear magnetic resonance, powder X-ray diffraction, differential scanning calorimetry, thermogravimetric analysis, ultraviolet−visible (UV−vis) spectroscopy, and scanning electron microscopy (SEM). Results showed that the product prepared by this method was analytically pure and had a high yield. No solvent was used in the reaction, and the byproduct water was in the form of water of crystallization. Moreover, SEM images showed that the method can directly obtain ultrafine powder products that are attractive to the pharmaceutical industry. Subsequently, kinetic analysis was performed by detecting the UV−vis spectra of the products under different optimized reaction conditions. The green chemistry metrics of the method showed that it is more environmentally friendly than the conventional solution method. In addition, the method was used in preparing a variety of N-acylhydrazone derivatives by using aldehydes with different substituents.

“…Researchers in the field of modifying traditional metal catalysts have conducted extensive research in order to achieve higher stability and improved catalytic efficiency. Metal–organic framework (MOFs) materials possess highly controllable porous structures and extremely high specific surface areas, making them have broad application potential in areas such as gas adsorption, separation and storage, and catalyst supports ( Juan et al, 2022 ; Tao et al, 2022 ; Juan et al, 2024 ). The structures and compositions can be precisely adjusted according to specific needs, endowing them with multifunctionality and sustainability ( Sanoop et al, 2017 ).…”

In solid propellants, combustion catalysts play a crucial role. Here, we introduce a convenient method for the self-assembly of UIO-66 (Mn) in the presence of water, leading to the preparation of Mn/C aerogels. The aerogels were successfully utilized in the thermocatalytic decomposition of ammonium perchlorate (AP). The results indicate that the incorporation of 2% mass fraction of Mn/C aerogels enhances the peak temperature of AP decomposition by approximately 87.5°C. Mn/C aerogels demonstrate excellent catalytic performance. In combination with kinetics, we propose a thermal catalytic mechanism.
