Abstract

Surface modification of titania with noble and semi-noble metals resulted in significant enhancement of photocatalytic activity. Presented data, showing the photocatalytic properties of TiO-M (where M is Pt and/or Cu) photocatalysts were further used as FeO@SiO/TiO-M magnetic nanocomposites shells in "Mono- and bimetallic (Pt/Cu) titanium(IV) oxide core-shell photocatalysts with Vis light activity and magnetic separability" [1]. Platinum and copper were photodeposited on four different titania matrices (commercial and self-obtained ones). The prepared photocatalysts were characterized by X-ray diffraction (XRD) analysis, specific surface area measurements using the Brunauer-Emmet-Teller (BET) isotherm, diffuse reflectance spectroscopy (DR-UV/Vis) analysis as well as scanning transmission electron microscopy (STEM) analysis. Photocatalytic properties were investigated in three different reactions: H generation, acetic acid oxidation to CO, and phenol degradation.

摘要

用贵金属和准贵金属对二氧化钛进行表面改性可显著提高其光催化活性。所呈现的展示TiO-M（其中M为Pt和/或Cu）光催化剂光催化性能的数据，进一步用作“具有可见光活性和磁分离性的单金属和双金属（Pt/Cu）二氧化钛核壳光催化剂”[1]中FeO@SiO/TiO-M磁性纳米复合材料壳层。铂和铜光沉积在四种不同的二氧化钛基质（商业的和自行制备的）上。通过X射线衍射（XRD）分析、使用布鲁诺尔-埃米特-泰勒（BET）等温线的比表面积测量、漫反射光谱（DR-UV/Vis）分析以及扫描透射电子显微镜（STEM）分析对制备的光催化剂进行表征。在三个不同反应中研究了光催化性能：氢气生成、乙酸氧化为二氧化碳以及苯酚降解。
