(CN107008334) 1. One photo catalytic decomposition of the catalyst-modified water hydrogen-make method, characterized in: at low-cost natural halloysite nanotubes (HNTs) as a carrier, to butyl phthalate, nickel nitrate, iron nitrate, cerium nitrate to form a precursor, synthesized in situ on the support surface nano-titanium dioxide (TiO2), is then subjected to impregnation, drying, calcination, hydrogen reduction step or the like, having a lattice defect in the composite carrier formed on the surface of the nickel ferrite catalyst sites, specifically comprises the following step: (1) after the natural halloysite nanotube iron, placed in a mixed solution of ethanol and water dissolved in ethanol solution a quantity butyl phthalate ; (2), magnetic stirring the solution in the addition (1), stirring was continued, and then filtered, dried, i.e. in the anatase-type titanium dioxide nano halioysite formed on the surface of the (2) titanium dioxide composite powder obtained in/halioysite ; (3) nickel nitrate was placed, ferric nitrate and cerium nitrate was immersed in mixed solution, and then dried, calcined, a final reduction with hydrogen, to give CeO2 -NiFe2 O4 /TiO2 -HNTs.
