Coordination polymers and metal-organic frameworks: materials by design.

The field of coordination polymers and metal–organic frameworks (MOFs) has evolved over a period of approximately 25 years to a stage where it is one of the most widely investigated areas of materials chemistry. The field has impacted many areas of science including commercial applications from gas storage agents to new investigations as drug-delivery vehicles [1]. Coordination polymers and MOF...

Aqueous Atrazine Removal by Activated Carbon / Metal Oxides Composites

In this work the removal of atrazine herbicide from aqueous medium was investigated using different catalysts based on activated carbon impregnated iron or chromium oxides. The materials were characterized by powder XRD, scanning electron microscopy (SEM) and infrared spectroscopy (FTIR). The characterization showed the formation of small particle size goethite (α-FeOOH) phase on activated carb...

Photochromism in composite and hybrid materials based on transition-metal oxides and polyoxometalates

Photochromic materials are attractive and promising for applications in many fields. One subject in this area is to prepare and study the photochromism in composite or hybrid materials based on transition-metal oxides or polyoxometalates. Their properties not depend only on the chemical nature of each component, but also on the interface and synergy between them. Since the charge transfer plays...
