Photocatalytic hydrogen production over metal-doped Cd_xZn_(1-x)S under visible light

【摘要】：正Photocatalytic water splitting using solar energy has been regarded as an attractive solution to resolve the global energy and environmental problems,but most of the photocatalysts that have been reported only work in ultraviolet region due to their wide band gap.In order to use the solar energy more effectively,visible-light-driven photocatalysts must be developed.To control the band structure,both of the methods which are doping of foreign elements into active photocatalysts with wide band gap and making solid solutions between photocatalysts with wide and narrow band gaps are often used.
