英文摘要	To utilize visible-light solar energy to meet environmental and energy crises, black TiO2 as a photocatalyst is an excellent solution to clean polluted air and water and to produce H-2. Herein, black TiO2 with a crystalline core-amorphous shell structure reduced easily by CaH2 at 400 degrees C is demonstrated to harvest over 80% solar absorption, whereas white TiO2 harvests only 7%, and possesses superior photocatalytic performances in the degradation of organics and H-2 production. Its water decontamination is 2.4 times faster and its H-2 production was 1.7 times higher than that of pristine TiO2. Photoelectrochemical measurements reveal that the reduced samples exhibit greatly improved carrier densities, charge separation, and photocurrent (a 4.5-fold increase) compared with the original TiO2. Consequently, this facile and versatile method could provide a promising and cost-effective approach to improve the visible-light absorption and performance of TiO2 in photocatalysis.; NSF of China [91122034, 51125006, 61376056, 51402336]; Science and Technology Commission of Shanghai [13JC1405700, 14YF1406500]; SCI(E); EI; ARTICLE; huangfq@mail.sic.ac.cn; 17; 2614-2619; 7
