Synthesis and comparison of the activities of a catalyst supported on two silicate materials

Abstract

h i g h l i g h t s Immobilization of [W(CO) 3 I 2 (NCCH 3) 2 ] complex onto mesoporous supports. Synthesis and characterization of new mesoporous catalysts. The new catalysts exhibit great catalytic activity in the epoxidation of 1-octene. Recyclable catalysts with excellent reusability and stability.

Isoniazid‐sensing Behavior of a Hybrid Silsesquioxane and Cobalt Pentacyanonitrosylferrate‐based Nanocomposite

“…The advantage of using hybrid silsesquioxane-derived materials and nanocomposites is the development of new materials, due to their excellent thermal and mechanical aspects, low dielectric constant, well-defined inorganic framework at the nanosized scale level [8,9] and suitable properties for specific applications. In this context, silsesquioxanes can be applied in diverse technological areas, such as additives [10], glass and ceramic matrices precursors [11,12], dendrimer precursors [13][14][15][16], polymers [17,18], fluorescent polymeric materials [19,20]; liquid crystal precursors [21,22], organic-inorganic hybrid material precursors [23][24][25][26], silica interface precursors [27,28], in electroactive films [29]; as adsorbents [30][31][32], homogeneous and heterogeneous catalysts [33,34] and antibacterials and biocides [35]. They are also applied in thin films and coatings, aiming at several applications, including nanocomposites [36][37][38].…”
