    • A photocatalyst comprising ZnO instead of titanium is provided to reduce production costs of the photocatalyst significantly, and a photocatalyst in which ZnO is formed as nanowires is provided to obtain an electric potential required for the generation of hydrogen without the use of additional electrodes or the application of additional voltage by near fields generated from pointed ends of the nanowires. A near-field photocatalyst using near field light formed from an pointed end of a nanowire comprises: a substrate; and a base which is formed on the substrate and formed from nanomaterial comprising one or more selected from ZnO, TiO2, GaP, ZrO2, SiCdS, KTaO2, KTaNBO, CdSe, SrTiO3, Nb2O3, Fe2O3, WO2, SaO2 or mixture thereof as a main component, wherein the nanomaterial is formed in shapes of nanowires comprising a nanoneedle, a nanorod, and a nanotube. The ZnO nanomaterial has a diameter of less than 5 to 200 nm, and a length of 0.5 to 100 mum. The substrate is selected from a group consisting of a silicon substrate, a glass substrate, a quartz substrate, a Pyrex substrate, a sapphire substrate, and a plastic substrate. The ZnO nanomaterial is oriented on the substrate perpendicularly to the substrate. The ZnO nanomaterial is formed on the substrate by a metal-organic vapor-phase epitaxy process, a metal-organic chemical vapor deposition process, a sputtering process, a thermal or electron beam evaporation process, a pulse laser deposition process, a vapor-phase transport process, and a chemical synthesis process. Further, the nanomaterial is coated by a compound selected from a group consisting of MgO, CdO, GaN, AlN, InN, GaAs, GaP, InP or the mixture thereof.
