好像没有确定的数值,有的文献提到与制备方法有关,在4-6 eV之间,如Physical Review B 2004, 70, 045415;Adv. Funct. Mater. 2007, 17, 2133–2138(the work functions for rutile and anatase phases are calculated to be 4.9 and 5.1 eV);J. Phys. Chem. B 2002, 106, 5814-5819(4.1eV)。对于anatase, 其导带大概位于-4.40 eV,价带位于-7.60 eV(相对于真空能级0eV),由于是n型半导体,其Fermi能级靠近导带,因此功函数在4.5-5.0 eV是可能的,也有可能更大,取决于n掺杂的程度。
