Design and development of a titanium oxide photocatalyst able to work effectively under visible light irradiation by an advanced metal ion-implantation method

摘要

The effective utilization of solar beamsis one of the most important challenges in chemistrytoday not only for the conversion and storage of solarenergy but also for the reduction and elimination ofenvironmental pollution such as toxic air and water.Strong contenders as environmentally-harmoniouscatalysts are photocatalysts which are able to workeffectively under visible and/or solar lightirradiation. In this article, an advanced metalion-implantation method has been successfully appliedto improve the photocatalytic properties ofsemiconducting titanium oxide photocatalysts. Thecatalysts enables the absorption of visible light evenlonger than 450 nm so that they are able to operateeffectively as photocatalysts under visible or solarlight irradiation. The development of suchenvironmentally-friendly titanium oxidephotocatalysts can be considered a breakthrough in theefficient and large scale utilization of solar energyto address urgent environmental and energy needs for the 21st century.
