Abstract: A catalyst support structure may include a base material and a metal oxide support structure. The metal oxide support structure may be formed by loading a first concentration of precursors of a metal oxide onto the base material using incipient wetness impregnation (IWI) to form the catalyst support structure, performing a first calcination process on the catalyst support structure at a first temperature to produce first structures of the metal oxide, loading a second concentration of precursors of the metal oxide onto the catalyst support structure using IWI to at least partially cover the first structures of the metal oxide, and performing a second calcination process on the catalyst support structure at a second temperature lower than the first temperature to produce second structures of the metal oxide.

Abstract: An isopoly-vanadic acid coordination polymer catalyst, method of manufacturing the same, and application thereof are provided. The isopoly-vanadic acid coordination polymer catalyst has a chemical formula of [Co(atrz)(V2O6)]. The atrz is a 4-amino-1,2,4-triazole ligand, and [V2O6] is a binuclear vanadate anion. The isopoly-vanadic acid coordination polymer catalyst shows strong thermal stability, and it is easy to synthesize with high reproducibility. The isopoly-vanadic acid coordination polymer catalyst has a good catalytic activity towards the bulk ring-opening of p-dioxanone. The resulting poly(p-dioxanone) is stable and uniform. The high molecular weight of the resulting poly(p-dioxanone) has great potential in high polymer materials, in particular the field of medical high polymer materials.

Abstract: Processes for converting a hydrocarbon reactant into an alcohol compound and/or a carbonyl compound are disclosed, and these processes include the steps of forming a supported chromium catalyst comprising chromium in a hexavalent oxidation state, irradiating the hydrocarbon reactant and the supported chromium catalyst with a light beam at a wavelength in the UV-visible spectrum to reduce at least a portion of the supported chromium catalyst to form a reduced chromium catalyst, and hydrolyzing the reduced chromium catalyst to form a reaction product comprising the alcohol compound and/or the carbonyl compound. The supported chromium catalyst can be formed by heat treating a supported chromium precursor, contacting a chromium precursor with a solid support while heat treating, or heat treating a solid support and then contacting a chromium precursor with the solid support.

Abstract: Methods for synthesizing a mesoporous nano-sized ultra-stable Y zeolite include adding sodium aluminate and colloidal silica to an aqueous NaOH solution and mixing to form a hydrogel having a molar ratio composition of 8 to 12 Na2O:Al2O3:14 SiO2:200 to 400 H2O. The method further includes heating the hydrogel to an autoclave to form a zeolite precursor which is filtered and washed to form a nano-sized Y zeolite. Further the method includes combining the nano-sized Y zeolite with water to form a nano-sized Y zeolite slurry mixture and then adding a 0.1 to 2.0 M aqueous solution of ammonium hexafluorosilicate to form a dealuminated solution. Finally the method includes filtering and washing the dealuminated solution with water to form an ultra-stable Y zeolite precursor, drying the ultra-stable Y zeolite precursor, and calcining the dried zeolite precursor to form the nano-sized ultra-stable Y zeolite.

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.
