Hybrid inorganic/organic adsorbents were synthesized using mixtures of diatomite and carbon charcoal as precursors, and explored for the removal of p-cresol from aqueous solution. The carbon/diatomite composites displayed a bimodal and interconnected porous structure which was partially inherited from both precursors. They display moderate surface areas (between 100 and 400 m(2)g(-1)) due to th...

We discuss density functional theory calculations of hybrid inorganic-organic systems that explicitly include the global effects of doping (i.e., position of the Fermi level) and the formation of a space-charge layer. For the example of tetrafluoro-tetracyanoquinodimethane on the ZnO(0001[over ¯]) surface we show that the adsorption energy and electron transfer depend strongly on the ZnO doping...

An inorganic-organic hybrid fluorescence chemosensor (DA/SBA-15) was prepared by covalent immobilization of a dansylamide derivative into the channels of mesoporous silica material SBA-15 via (3-aminopropyl)triethoxysilane (APTES) groups. The primary hexagonally ordered mesoporous structure of SBA-15 was preserved after the grafting procedure. Fluorescence characterization shows that the obtain...

Constructing a highly efficient bulk-heterojunction is of critical importance to the hybrid organic/inorganic solar cells. Here in this work, we introduce a novel hybrid architecture containing P3HT nanowire and CdSe nanotetrapod as bicontinuous charge channels for holes and electrons, respectively. Compared to the traditionally applied P3HT molecules, the well crystallized P3HT nanowires quali...

Poly (vinylpyrrolidone)-grafted silica as an organic-inorganic hybrid material was used as an effective heterogeneous polymeric cosolvent catalyst in organic reactions. This modified silica catalyzed nucleophilic displacement of alkyl halides for easy preparation of alkyl thiocyanates, alkyl cyanides, alkyl azides and alkyl aryl ethers. Furthermore, the catalyst was applied for the conversion o...

Hybrid organic-inorganic materials offer a wide range of interesting applications especially in optics. Chemistry plays a major role in the elaboration and comprehension of such materials. Sol-gel process provide a method to blend, down to the molecular scale, organic and inorganic components. Examples of hybrid organic-inorganic materials for optics and optical characterizations of hybrid mate...

We present the design and development of hybrid organic – inorganic materials with improved electrochemical performance to be used in energy storage applications (e.g. supercapacitors). The systematic study carried out shows various carbon–based materials (e.g. activated carbons, graphene based materials) working as active substrates where the anchoring of inorganic species takes place (i.e. po...

Nanocomposite membrane comprising of both organic and inorganic material qualities have become a prime focus for the next generation membranes. Nanocomposite may consist of hard permeable or impermeable inorganic particles, such as zeolites, carbon molecular sieves and, silica and carbon nanotubes, metal oxide blended with continuous polymeric matrix presents an attract...
