Abstract: A method of upcycling polymers to useful hydrocarbon materials. A catalyst with nanoparticles on a substrate selectively docks and cleaves hydrocarbon chains forming shorter hydrocarbon chains. The catalyst includes metal nanoparticles, such as monometallic nickel or ruthenium nanoparticles or a plurality of nanoparticles of two or more metals, on a metal oxide substrate.

Abstract: A method of upcycling polymers to useful hydrocarbon materials. A catalyst with nanoparticles on a substrate selectively docks and cleaves longer hydrocarbon chains over shorter hydrocarbon chains. The nanoparticles exhibit an edge to facet ratio to provide for more interactions with the facets.

Abstract: A catalyst for oxidative dehydrogenation of alkanes includes a substrate including an oxide; at least one promoter including a transition metal or a main group element of the periodic table; and an oxidation-active transition metal. The catalyst is multimetallic.

Abstract: The invention is directed to a catalyst and a method for making a reforming catalyst for the production of hydrogen from organic compounds that overcomes the problems of catalyst poisoning and deactivation by coking and high temperature sintering, yet provides excellent durability and a long working life in process use. An embodiment is the formation of a unique four-metal ion hexa-aluminate of the formula M1aM2bM3cM4dAl11O19-?. M1 and M2 are selected from the group consisting of beryllium, magnesium, calcium, strontium, barium, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, and gadolinium. M3 and M4 are selected from the group consisting of chromium, manganese, iron, cobalt, nickel, copper, molybdenum, ruthenium, rhodium, palladium, tungsten, rhenium, osmium, iridium, platinum, wherein 0.010?a+b+c+d?2.0. Also, 1???1. Further, M1?M2 and M3?M4.
