In this study, a facile one-pot method was developed to create hierarchical porous M−ZIF−8 by utilizing NaOH as defecting agent. The as-synthesized material comprising macroporous and mesoporous exhibits porosity. TiO2 (anatase) with different mass ratios (5%, 15%, 25%) were immobilized into combine the synergism of adsorption photocatalytic oxidation. Five percent in gave best degradation. kin...

In recent years, alternative methods to conventional synthesis of MOFs (metal-organic frameworks) have emerged due the problematic use solvents for both environment and human health. Here we present ZIFs (zeolitic imidazolate at high pressure by means a hydraulic press provided with heating mechanism. By optimization parameters such as temperature, time addition promotor NH4NO3, considerable in...

A novel ZIF-8 assisted polyacrylamide functionalized silica polar stationary phase was prepared by a facile method of adding nanoparticles and into (PAM) aqueous solution, then stirring the mixture until solution evaporated absolutely with help mechanical agitator. Interestingly, (PAM-Sil@ZIF-8/PAM) showed favorable hydrophilicity, as demonstrated good separation performance strong retention ab...

Doping heteroatoms such as nitrogen (N) and boron (B) into the framework of carbon materials is one most efficient methods to improve electrical performance carbon-based electrodes. In this study, N-doped has been facilely synthesized using a ZIF-8/polydopamine precursor. The polyhedral structure ZIF-8 effective surface-coating capability dopamine enabled formation with hollow structure. polyhe...

A sensitive and flexible detection method for organophosphorus pesticides (OPs) is a crucial request to avoid their further expanded pollution. Herein, an acetylcholinesterase (AChE) electrochemical sensor, based on the co-modification of ZIF-8 graphene (GR), was constructed OPs. ZIF-8/GR composite can provide stable biocompatible environment loading AChE accelerate chemical reaction electrode ...

ABSTRACT. The utilization of a metal organic framework (ZIF-8) modified by Fe3O4 nanoparticles was used to accomplish adsorption Rhodamine B (RB) from aqueous solutions. SEM, XRD, IR, and BET analyses were all characterize the composite (Fe3O4@ZIF-8). surface area this adsorbent 478.4 m2/g. X-Ray diffraction spectroscopy detect modification utilizing electron microscopy (SEM) scanning with 48 n...

The production of 1-butene by ethylene dimerization is an important chemical industrial process currently implemented using homogeneous catalysts. Here, we describe a highly active heterogeneous catalyst (Ni-ZIF-8) for dimerization, which consists isolating Ni-active sites selectively located on the crystal surface zeolitic imidazolate framework. Ni-ZIF-8 can be easily prepared simple one-pot s...
