• Abstract

  Metal-Organic Frameworks (MOFs) are a special class of coordinating polymers formed by the interaction between metal ions or clusters and multitopic organic linkers. The great interest in these materials are related to properties such as high crystallinity, permanent microporosity, high surface area values, low density and high thermal and chemical stability (in some cases). Within this p…

• Abstract

  Carbon dioxide is one of the more important gases responsible for greenhouse. Today global emissions of CO2 are in the order of 49 billion tons. In this context, the goal of this project is to develop two different strategies so they can, in the near future, constitute in alternative methods for the carbon dioxide reduction in the atmosphere. The first of them focuses on the synthesis of …

• Abstract

  Metal-Organic Frameworks (MOFs) are highly porous and selective materials known as inorganic polymer structures in which metal clusters are connected by organic spacers. This new class of materials has been highlighted as adsorbent material of heavy metals and organic dyes. Contamination of water from industrial effluents containing such substances is a concern because its harmful effects…

• Abstract

  Rare-Earth based Infinite Coordination Polymers (RE-ICPs) are multifunctional materials since they can have several properties such as permanent porosity and luminescence. In addition, these compounds usually exhibit homogeneous spherical nanocrystalline particles, with micro- or nanometric dimensions. For these reasons, this class of materials can have potential applications in different…

• Abstract

  Lanthanide (III) ions are important in several current technological applications, such as in the catalytic and electronics industries. However, these metals have relatively low abundance in Earth's crust. In addition, there is a growing concern about the disposal of these materials into the environment since the environmental impact and toxicity are not yet known in detail. For this reas…
