【摘要】:正Photocatalysis is an environmentally-friendly technology,which can supply an ambient-temperatureprocess to completelydecompose organic contaminants,split water to produce cleanhydrogen energy,and convert CO_2 to hydrocarbon fuel usingsolar light.Thus it will potentially be embraced into the futuresustainable-development strategy.From the view of effectivelyutilizing solar energy,developing highly efficient visible-lightsensitivephotocatalysts is highly anticipated and thus has attractedextensive attention.During re-
