摘要
(CN107008334) 种​光​催化​分解​水​制​氢​催化剂​的​改性​方法,以​低成本​天然​埃洛​石​纳米​管(HNTs)为​载体,以​钛​酸​丁​酯、硝酸​镍、硝酸​铁、硝酸​铈​为​前驱​物,在​载体​表面​原位​合成​纳米​二氧化钛(TiO),然后​经过​浸渍、干燥、煅烧、氢​还原​等​工序,在​复合​载体​表面​生成​具有​晶格​缺陷​的​铁​酸​镍​铈​催化​活性中心。本​发明​的​优点​是:该​方法​工艺​简单,操作​方便,成本​低,光​催化​中心​高度​分散,催化剂​活性​高,光​生​电子​复合​率​低,且​催化剂​具有​抗​烧结​和​坍塌​特性。

主权利要求
(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.
