中文摘要: |
以熔盐法和固相法分别制备了5个钛酸锶光催化剂,并采用XRD、BET、SEM等表征了制备样品的性质.熔盐法制备的样品呈现立方体小颗粒状.采用浸渍法,在钛酸锶的表面担载氧化镍助催化剂,评价了该光催化剂光解水的催化活性.结果表明光解水催化剂钛酸锶的制备过程明显影响催化剂的反应活性.NaCl为熔盐时制备的SrTiO 3晶体光催化反应活性好于固相法制备的晶体,能够有效分解纯水制备氢气和氧气. |
英文摘要: |
The five photocatalysts of SrTiO 3 were prepared by molten salt synthesis (MSS) process and solid state reaction (SSR) process. The properties of the obtained samples were characterized by X-ray diffraction, BET and scanning electron microscope. The samples obtained by the MSS process showed the cubic particles. NiO x as a co-catalyst was coated on the surface of SrTiO 3 by an impregnated process, and the photocatalysis reactions for water splitting were evaluated with the NiO x -SrTiO 3 catalyst. The experimental results show that the photocatalysis reactivity of SrTiO 3 is influenced obviously by the synthesis process. And the reactivity of SrTiO 3 prepared by MSS process with NaCl is better than that of SSR process. The water can be split into hydrogen and oxygen effectively. |
