METAL-ORGANIC FRAMEWORK FUNCTIONALIZED POLYMERIC COMPOSITIONS
A polymeric composition includes an organic polymeric substrate and metal-organic frameworks on the surface of the polymeric substrate. The metal-organic frameworks cover at least 90% of the surface area of the polymeric substrate.
Homogeneous Catalysts That Are Recoverable By Host Guest Interactions
A method for separating a homogeneous catalyst from a solution includes forming a host-guest compound between a first isomer of the catalyst and inclusion compound in the solution and isolating the host-guest compound from the solution. The catalyst may be released from the inclusion compound by converting the first isomer of the catalyst to a second isomer of the catalyst.

Water Soluble Homogeneous Catalysts That Are Recoverable By Phase Selectivity And Host-Guest Interactions
A chemical reaction is catalyzed in an organic solvent using a water soluble N-heterocyclic carbene homogeneous catalyst to form a reaction mixture. An aqueous phase in the reaction mixture. A solvent in which the catalyst is insoluble is added to the reaction mixture, causing the catalyst to migrate to the aqueous phase to form a catalyst-laden aqueous phase. The catalyst is extracted from the catalyst-laden aqueous phase.

A method for separating a homogeneous catalyst from a solution includes forming a host-guest compound between a first isomer of the catalyst and inclusion compound in the solution and isolating the host-guest compound from the solution. The catalyst may be released from the inclusion compound by converting the first isomer of the catalyst to a second isomer of the catalyst.
METHOD FOR PREPARING PARTICLES SUITABLE FOR CATALYSING OXYGEN REDUCTION OR HYDROGEN OXIDATION, THE PARTICLES BEING PROTON-CONDUCTING BY GRAFTING SPECIFIC PROTON-CONDUCTING FLUORINATED POLYMERS TO THE SURFACE THEREOF
A method for preparing particles comprising a material suitable for catalysing oxygen reduction or hydrogen oxidation, the particles being grafted with grafts consisting of at least one specific polymer comprising at least one repeating fluorinated styrene unit bearing at least one proton-conducting group.
Water soluble homogeneous catalysts that are recoverable by phase selectivity and host-guest interactions
This describes homogeneous catalysts that are recoverable from solution by being phase selective and through host-guest interactions. An example of a method includes separating a water soluble N-heterocyclic carbene homogeneous catalyst from a solution by: (a) forming a host-guest compound between the catalyst and an inclusion compound in the solution; and (b) isolating the host-guest compound from the solution.
Catalytic upcycling of polyolefins via versatile alkylaluminums
Disclosed herein is a process for the conversion of polymers, oligomers, or mixtures thereof into shorter alkanes, carboxylic acids, alcohols, alkyl halides or aldehydes. This process includes contacting the polymers, oligomers, or mixtures thereof with the compound of formula (I):
Al(R.sup.1).sub.3(I)
where R.sup.1 is independently selected at each occurrence thereof from the group consisting of H, aryl, C.sub.1-C.sub.8 alkyl, and C.sub.1-C.sub.8 alkoxy, as a reaction mixture, in the presence of a catalyst selected from the group consisting of a transition metal catalyst, a lanthanide series metal catalyst, or combinations thereof.
Hydrogenation catalyst, its method of preparation and use
A method of preparing a hydrogenation catalyst, for example, a phthalate hydrogenation catalyst, comprising contacting a silica support having a median pore size of at least about 10 nm with a silylating agent to form an at least partially coated silica support, calcining said coated silica support to form a treated silica support, and depositing a noble metal, preferably ruthenium, on the treated silica support, and optionally contacting the treated silica support with an optional chelating agent to form the hydrogenation catalyst; a hydrogenation catalyst prepared by that method; and a method of hydrogenating unsaturated hydrocarbons, such as phthalates, in which an unsaturated hydrocarbon is contacted with hydrogen gas in the presence of the hydrogenation catalyst of the invention.
