Abstract: Methods for synthesizing a mesoporous nano-sized ultra-stable Y zeolite include combining a microporous Y zeolite having a SiO2/Al2O3 molar ratio of less than 5.2 with water to form a microporous Y zeolite slurry and heating the microporous Y zeolite slurry to 30° C. to 100° C. to form a heated microporous Y zeolite slurry. Further the method includes adding a 0.1M to 2.0M ammonium hexafluorosilicate solution and a 0.1M to 2.0M ammonium hydroxide solution in a drop-wise manner, either sequentially or simultaneously, to the heated microporous Y zeolite slurry to form a treated zeolite solution and holding the treated zeolite solution at 50° C. to 100° C. 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: The present invention combines the advantages of fabrication of semiconductor heterostructure (Ag3PO4—WO3) with plasmonic metals (Pt and Ag) with optical interference to optimize the visible light photo response of plasmonic metals deposited semiconductor (Pt—Ag/Ag3PO4—WO3) for visible light assisted H2 generation utilizing the aqueous bio-alcohols. Crystalline Ag3PO4 and WO3 nanofibers were synthesized by microwave and electrospinning methods. Three different WO3 nanofibers composition (5, 10 and 15 wt. %) were used to obtain Ag3PO4/WO3 nanocomposite heterostructures, which are effective visible light active photo catalysts. Further, a simple, enviro-friendly, and cost-effective biogenic synthesis method have been achieved using Salvia officinalis extract to decorate Pt and Ag metal nanoparticles on the surface of Ag3PO4—WO3 composites. Presence of bioactive agents in the extract are responsible for the Pt and Ag3PO4 reduction and for prevention of the Pt nanoparticles from aggregation in aqueous medium.

Abstract: A nanocatalyst for partial oxidation of methane is disclosed. The nanocatalyst is prepared by carbonizing a metal-organic framework coordinated with copper ions to form a structure in which nitrogen atoms present in a nitrogen-doped porous carbon structure form coordinate bonds with copper ions. This structure enhances the chemical stability of the nanocatalyst, prevents the peroxidation of methane at low temperature, and significantly improves the conversion efficiency of methane to liquid products such as methanol and methyl hydroperoxide by selective partial oxidation of methane gas. Also disclosed are a method for preparing the nanocatalyst and a method for partial oxidation of methane using the nanocatalyst.
