Abstract: A solid-supported Pd catalyst is suitable for C—C bond formation, e.g., via Suzuki-Miyaura and Mizoroki-Heck cross-coupling reactions, with a support that is reusable, cost-efficient, regioselective, and naturally available. Such catalysts may contain Pd nanoparticles on jute plant sticks (GS), i.e., Pd@GS, and may be formed by reducing, e.g., K2PdCl4 with NaBH4 in water, and then used this as a “dip catalyst.” The dip catalyst can catalyze Suzuki-Miyaura and Mizoroki-Heck cross coupling-reactions in water. The catalysts may have a homogeneous distribution of Pd nanoparticles with average dimensions, e.g., within a range of 7 to 10 nm on the solid support. Suzuki-Miyaura cross-coupling reactions may achieve conversions of, e.g., 97% with TOFs around 4692 h−1, Mizoroki-Heck reactions with conversions of, e.g., a 98% and TOFs of 237 h−1, while the same catalyst sample may be used for 7 consecutive cycles, i.e., without addition of any fresh catalyst.

Abstract: A catalyst that includes heterogeneous metal carbide nanomaterials and a novel preparation method to synthesize the metal carbide nanomaterials under relatively mild conditions to form an encapsulated transition metal and/or transition metal carbide nanoclusters in a support and/or binder. The catalyst may include confined platinum carbide nanoclusters. The preparation may include the treatment of encapsulated platinum nanoclusters with ethane at elevated temperatures. The catalysts may be used for catalytic hydrocarbon conversions, which include but are not limited to, ethane aromatization, and for selective hydrogenation, with negligible green oil production.

Abstract: A catalyst includes a support, where the support includes an external surface, about 60 wt % to about 99 wt % silica, and about 1.0 wt % to about 5.0 wt % alumina. A catalytic layer is disposed within the support adjacent to the external surface, where the catalytic layer further includes Pd, Au, and potassium acetate (KOAc). In the catalyst, (a) the KOAc is from about 60 kg/m3 to about 150 kg/m3 of the catalyst; or (b) the catalytic layer has an average thickness from about 50 μm to about 150 μm; or (c) both (a) and (b). The catalyst also possesses a Brunauer-Emmett-Teller surface area of about 130 m2/g to about 300 m2/g and a geometric surface area per packed bed volume from about 550 m2/m3 to about 1500 m2/m3. The catalyst is highly active for the synthesis of vinyl acetate monomer and exhibits a high selectivity for vinyl acetate monomer.

Abstract: The present invention relates to carbon fiber composites and a method for producing the same. By reducing specific transition metal ions with a specific concentration, the method for producing the carbon fiber composites can form nanoparticles of a transition metal on an outer surface of a titanium dioxide layer encapsulating a carbon fiber to produce the carbon fiber composites. The nanoparticles of the transition metal directionally contact the titanium dioxide layer, so that the carbon fiber composites have synergistically photocatalytic activity.

Abstract: Methods of making robust bijels include dispersing metal oxide precursors and/or metal salts into at least one phase of a bijel and hydrolyzing and condensing the metal oxide precursors and/or metal salts in a sol-gel reaction to form sintered bridges between interfacially jammed surface-active nanoparticles. The methods can be used with any bijels, including those produced during solvent transfer-induced phase separation (STRIPS) methods and other methods. A robust bijel includes chemically sintered bridges between the interfacially jammed surface-active nanoparticles. Methods of making nanocatalyst-functionalized sintered bijels include adsorbing metal salts to a surface of sintered interfacially jammed nanoparticles of bijels, and reducing the metal precursors on the surface of the sintered nanoparticles. Nanocatalyst-functionalized sintered bijels include catalytically active metal or metal oxide nanocatalysts on a surface of the sintered interfacially jammed surface-active nanoparticles.
