Synthesis and characterization of metal–organic frameworks fabricated by microwave-assisted ball milling for adsorptive removal of Congo red from aqueous solutions

Abstract

In this study, four metal–organic frameworks (MOFs) were prepared using a simple, low-cost, and high-efficiency technique utilizing simple carboxylic acids and metal salts by microwave-assisted ball milling.

Comparison Study on the Adsorption Capacity of Rhodamine B, Congo Red, and Orange II on Fe-MOFs

“…Fe-MOFs were synthesized by microwave-assisted ball milling on the basis of a previously reported way [ 48 ]. H 3 BTC (98%) and FeSO 4 ·7H 2 O were purchased from Shanghai Aladdin Biological Technology Co., Ltd. (Shanghai, China), while potassium dichromate (≥99.8%) was purchased from Tianjin Zhiyuan Chemical Reagent Co., Ltd. (Tianjin, China).…”

“…Microwave-assisted ball milling was first described by our laboratory and is based on a solid-liquid ball-milling (MSBM) approach that involves using a ball-milling machine in a microwave oven [ 41 , 42 , 43 , 44 , 45 , 46 ]. The coupling of mechanical milling with microwaves enables certain nanocrystal materials, such as magnetic and metal oxidation ferrite, to be generated at room temperature [ 47 , 48 , 49 ]. In the present study, MOF-based adsorptive removal of hazardous compounds, including RhB, Orange II, and CR, from aqueous media was investigated.…”

The synthesis of biodiesel using copper based metal-organic framework as a catalyst

“…Many studies have shown the synthesized of CuBTc MOF and its use in various applications, such as being used as an ion exchanger, adsorption agent, reduction agent, and antioxidant agent [6][7][8][9][10][11]. However, there are still no studies investigating the potential of CuBTc-MOF to catalyze biodiesel production thus far.…”

An Effective Microwave-Assisted Synthesis of MOF235 with Excellent Adsorption of Acid Chrome Blue K

“…The intensities of all crystallinity peaks which increased gradually in short periods could be attributed to the fast heating precursor and avoid thermal gradients [20,21]. It also demonstrated that the increased irradiation time leads to high yields and Journal of Nanomaterials larger crystals [22]. It indicated that microwave heating was more effective than the convenient heating.…”
