Structures and unexpected dynamic properties of phosphine oxides adsorbed on silica surfaces.
نویسندگان
چکیده
Solid-state NMR spectroscopy of selected phosphine oxides adsorbed on silica surfaces establishes the surface mobilities, even of phosphine oxides with high melting points. Crystal structures of the adducts Ph3 PO⋅HOSiPh3 and Cy3 PO⋅H2 O indicate that the interactions with silica involve hydrogen bonding of the P=O group to adsorbed water and surface silanol groups.

Origin of Catalytic Activity Differences between Phosphine and Phosphine Oxide-Based Structures in the Water-Crosslinkable Polyalkoxysilane Composition
Organocatalysts have attracted enormous interest in the water-crosslinking reaction in silane-grafted polyolefins (SGPOs) system owing to their simplicity, low toxicity and environmentally benign nature compared to organotin catalysts, which are most used in SGPOs system. We focus on organophosphorus compounds including four structure types as organocatalysts; phosphoric acids, phosphoric ester...
متن کاملSupercritical water impregnation of CuO nanoparticles on silica-support as new catalyst
In our current study, supercritical water impregnation (SCWI) was introduced as a unique catalyst preparation method by employing the high diffusivity property of supercritical water. The method allows nano-particles to place on support surfaces in extremely dispersed conditions. The silica-based nanocatalyst granules for this purpose were prepared by initial impregnation of highly porous silic...

Molecular thin films utilizing phosphonates are widely used in a variety of chemical applications, such as surfactants, stabilization of nanoparticle suspensions, layer by layer film formation, and more. Furthermore, surface chemistry is a valuable tool in the context of semiconducting materials. To date, the studies of monolayer formation of phosphonates have mainly focused on phosphonic acids...
متن کاملExtraction of Co(II) by Isocyanate Treated Graphite Oxides (iGOs) Adsorbed on Surfactant Coated C18 Before Determination by FAAS
A simple, highly sensitive, accurate and selective method for determination of trace amounts of Co(II) in water samples is presented. Isocyanate treated graphite oxides (iGOs) solid phase extraction adsorbent was synthesized by covalently isocyanate onto the surfaces of graphite oxides. The stability of a chemically (iGOs) especially in concentrated hydrochloric acid which was then used as a re...
