Gas–solid two-phase flow (GSF) mechanochemical synthesis of dual-metal–organic frameworks and research on electrochemical properties

Abstract

As an alternative approach for conventional mechanochemical synthesis, a novel gas–solid two-phase flow (GSF) synthetic technique for the mechanochemical synthesis of dual metal–organic frameworks (DMOFs) was reported for the first...

Continuous, Solvent-Free, and Mechanochemical Synthesis of N-Acylhydrazone Derivatives by Spiral Gas–Solid Two-Phase Flow

“…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.…”

Manufacturing of urea co-crystals by spiral gas–solid two-phase flow (S-GSF) based on spiral jet mills: a continuous, solvent-free, and scalable mechanochemical method

“…Based on the shortcomings of traditional mechanochemical methods, our group reported a gas-solid two-phase flow (GSF) technique. [25][26][27][28] The technology is based on the principles of hydrodynamic theory, and it utilizes a high-speed carrier gas to accelerate the reactant particles to supersonic speed. The high-speed moving particles convert the huge kinetic energy into activation energy needed to overcome the chemical reaction by hitting the target or collision.…”

Gas–solid two-phase flow method for preparing trimesic acid series MOFs for catalytic thermal decomposition of ammonium perchlorate

“…Therefore, by combining numerous factors, the present work is based on a new device for mechanical and chemical reactions designed and developed by the group, i.e., the gas-solid two-phase flow (GSF) low-heat solid-phase synthesis device. [27][28][29] This device works based on the principle of fluid dynamics theory, that is, the reaction material is driven by high-speed airflow, the reactant particles instantaneously hit the target head, and the mechanical energy is converted into the activation energy required to overcome the chemical reaction, thus promoting the chemical reaction. This method has the advantages of a simple and solvent-free process, high product purity, and easy industrial production.…”
