Abstract: The present disclosure is related to a method for preparing a gaseous- or liquid-nitridation treated core-shell catalyst and, more specifically, to a method for preparing a gaseous- or liquid-nitridation treated core-shell catalyst comprising steps of: nitridation-treating a transition metal precursor core and noble metal precursor shell particles in the presence of a gaseous nitrogen source; or forming a transition metal precursor core and noble metal precursor shell particles, by means of a liquid nitrogen source, and at the same time allowing the nitrogen source to bond with the transition metal precursor and thus allowing nitridation treatment. Therefore, the present disclosure allows a high nitrogen content in the core and thus enables a prepared catalyst to have excellent durability, a small average particle size and high degree of dispersion and uniformity, and thus to be suitable for the fuel cell field.

Abstract: Zeolites are industrially important materials possessing high Bronsted acidity and shape-selectivity. However, their inherently small pores restrict application for catalytic conversion of bulky molecules. A method of synthesis of ‘artificial’ zeolites. The artificial zeolites have well-tailored Bronsted and Lewis acid sites prepared on mesostructured silica to circumvent this limitation. This novel approach utilizes atomic layer deposition to tailor both porosity and acid speciation, providing exquisite control over catalytic behavior and enabling systematic studies.

Abstract: A zero-valent metal polymeric complex supporter (ZVM-PCS) is disclosed. PCS possesses porous surface and internal coralloid-like channel structure that can accommodate high amount of iron-containing materials and derivatives thereof. The surface pore size, porosity, hydrophilicity and internal coralloid-like channel structure of PCS can be tailored through the manufacturing process, with which PCS can be functioned as a regulator for the releasing of produced hydrogen, and also control the adsorption and reactions toward heavy metals and chlorinated volatile organic compounds in water. The released hydrogen from the ZVM-PCS can be applied to anaerobic bioremediation. Moreover, the ZVM-PCS can be developed as the filter materials that can be installed in a column or any storage for water and wastewater treatment, or even in a groundwater cut-off barrier for the cleanup of contamination. While the ZVM-PCS is synthesized as a film without openings, it can be used as the electromagnetic interference shielding material.

Abstract: A semiconductor material basically consists of titanium oxide, with the special feature of being like nanostructures, which gives special physicochemical properties, with ability to disperse and stabilize metal particles with high activity and selectivity in catalytic processes mainly. The process of producing the semiconductor material includes adding a titanium alkoxide to an alcoholic solution, adding an acid to the alcoholic solution, controlling the pH from 1 to 5; subjecting the acidic solution to agitation and reflux conditions at 70 to 80° C.; stabilizing the medium and adding bidistilled water in a water/alkoxide molar ratio of 1-2/0.100-0.150, continuing with reflux until gelation; aging the gel for 1 to 24 hours for complete formation of the titania; drying the titania nanostructured at of 50 to 80° C. for about 1 to 24 hours, and subjecting the dried titania to a calcination step at 200 to 600° C. for 1 to 12 hours.
