Mechanochemical synthesis of highly porous materials

Abstract

Mechanochemistry became a powerful and popular method for the preparation of various porous materials.

Mechanochemically assisted hydrolysis in the ADOR process

“…A promising methodology is mechanochemistry, applicable in different elds of chemistry, as shown in various literature reviews. [32][33][34][35][36][37][38][39][40][41] The applicability and importance of mechanochemical methods for zeolite chemistry has recently been outlined by Pérez-Ramírez and co-workers 42 as well as Morris and James. 43 Reducing the amount of solvent (solvent-assisted methods) or even omitting it altogether (solvent-free approaches) could lead, and in some cases already has led, to improvements in terms of the quantity of waste products and in energy efficiency, resulting in an overall more economical process.…”

A Brief Overview on Antioxidant Activity Determination of Silver Nanoparticles

“…The most common technique for nanoparticles preparation is the reduction by reducing agents of organic or inorganic character, for example sodium ascorbate, hydrogen, N , N -dimethyl formamide, or sodium borohydride. The principle of AgNPs preparation is the reduction of Ag + ion to metallic form Ag 0 which is followed by agglomeration into oligomeric clusters leading to the formation of metallic colloidal AgNPs [ 92 ]. To avoid the agglomeration of nanoparticles, it is necessary to use stabilizing agents, such as poly(vinyl alcohol), poly(vinyl pyrrolidine), or polyethylene glycol [ 93 , 94 , 95 ].…”

Ambient Temperature Graphitization Based on Mechanochemical Synthesis

“…In this respect, an alternative and promising solution is mechanochemistry. In the mechanochemical process, the energy needed to initiate and stimulate the chemical reactions is generated by mechanical treatment, leading to rapid and efficient solid state transformation with no heat supply [31–35] . The synthesis procedure is shown in Figure 1 A.…”

[31][32][33][34][35] The synthesis procedure is shown in Figure 1 A. The g-C 3 N 4 precursor (2 g) and Mg powder were mixed, placed in a stainless-steel reactor along with ball bearings, and treated by high-speed vibrating ball milling, affording the product (ca.…”
