The present invention is to provide a catalyst for hydrocracking that is capable of decreasing the content of oxygen components contained in hydrocarbons synthesized from a vegetable fat or oil, an animal fat or oil, and/or a coal liquefaction oil each containing at least one selected from a fatty acid, a fatty acid ester, and an alkylphenol compound, and a hydrocarbon production method using the same. The catalyst for hydrocracking of the present invention contains a carrier containing a porous oxide, and nickel and molybdenum supported on the carrier, the catalyst for hydrocracking being subjected to a hydrogen reduction treatment, and having a mass ratio (X/(X+Y)) of a nickel content (X) in terms of nickel oxide (NiO) to the sum of the nickel content (X) in terms of nickel oxide (NiO) and a molybdenum content (Y) in terms of molybdenum oxide (MoO.sub.3) of 0.5 or more and 0.9 or less. The hydrocarbon production method of the present invention includes producing hydrocarbons from a vegetable fat or oil, an animal fat or oil, and/or a coal liquefaction oil each containing at least one selected from a fatty acid, a fatty acid ester, and an alkylphenol compound, by using the catalyst for hydrocracking of the present invention.

Single crystalline nanoparticles that are tantalum nitride doped with at least one metal are described. The single crystalline nanoparticles can be doped with two metals such as Zr and Mg. The single crystalline nanoparticles can be Ta.sub.3N.sub.5:Mg+Zr, or Ta.sub.3N.sub.5:Mg, or Ta.sub.3N.sub.5:Zr or any combination thereof. Catalyst containing the single crystalline nanoparticles alone or with one or more co-catalyst are further described along with methods of making the nanoparticles and catalyst. Methods to split water utilizing the catalyst are further described.

A method to make delta-valerolactone (DVL) by dehydrogenating 2-hydroxytetrahydropyran (HTHP). The HTHP is contacted with a supported-metal catalyst for a time, at a temperature, and at a pressure wherein at least a portion of the HTHP is converted to DVL via dehydrogenation of the HTHP. The HTHP may be derived from biomass. Thus, the method yields DVL without requiring a petroleum-based feedstock.
