The photocatalytic hydrogen evolution and electrochemical behaviors of Kiggen-type XW12O40n- (X=P,Ge and Si) are investigated. It is found that the two-electron reduced species are active for H+ reduction and the more negative the potential of XW12O40(n+2)-/(n+1)- is,the higher the activity for hydrogen evolution is.
