Abstract:

The use of solar energy through titanium dioxide, one of the most promising semiconductor photocatalyst, is a possible solution to energy shortage and environmental pollution. In this paper, anatase carbon-incorporated TiO2 microspheres are prepared by a facile flame thermal approach, which is annealing-free and almost no waste and simple. The photocatalytic hydrogen yield of the as-prepared TiO2 sample is tested by gas chromatograph under Xe lamp irradiation. Through this experiment, students can learn photocatalytic mechanism, the synthesis and characterization of semiconductor photocatalyst as well as know a little about solar energy, hydrogen energy and environmental awareness.

Key words: TiO2, Hydrogen energy, Comprehensive experiment, Environmentally friendly
