摘要

利用柠檬酸法制备了系列钙钛矿型复合氧化物LaFe

1-x

(x=0～0.07)

通过XRD、TEM、UV-VIS DRS、XPS和PLS等表征手段对其晶相结构、形貌、吸光特性和表面性质进行了表征

并结合光催化分解水反应评价了其产氢活性.结果表明:柠檬酸法制得的钙钛矿型LaFeO

为纳米级材料

其在紫外-可见光区具有较宽的吸收带

掺杂Cu

可增强对可见光的吸收; 在紫外光的激发下

系列纳米钙钛矿型LaFe

1-x

(x=0～0.07)具有一定的光催化分解水产氢活性

且掺杂Cu

可在一定程度上提高产氢量

其掺杂的最佳摩尔分数为0.05.

Abstract

Perovskite oxides LaFe

1-x

(x=0-0.07)was prepared by a conventional citrate complex method. The structure

shape

particle size

the photon absorption performance and surface property of the prepared LaFe

1-x

(x=0-0.07)were investigated by using XRD

TEM

UV-VIS DRS

XPS and PLS techniques. Perovskite oxides LaFeO

prepared is a kind of nano-sized material. Perovskite oxides LaFeO

has the good absorption property in UV-visible region

and a series of Cu-doped LaFeO

have more respondence to the visible light. Under UV light irr

adiation

can be produced by photocatalytic decomposingof water over the prepared LaFe

1-x

(x=0-0.07). Doping Cu

can enhance the photocatalytic activity of LaFeO

to a certain extent

and the optimal doping molar fraction of catalyst is 0.05.
