摘要：Dye-sensitized photoelectrochemical cell (DS-PEC) is an especially attractive method to generate hydrogen via visible light driven water splitting. Electrolyte, an essential component of DS-PEC, plays a great role in determining the photoactivities of devices for water splitting. When using phosphate buffer (pH = 6.4) as electrolyte, the DS-PEC displayed much higher photoactivity than using 0.1 M Na2SO4(pH = 6.4) as electrolyte. The insight is phosphate anion gathers together to form a negative electrostatic field on TiO2surface, which increases the resistance in the TiO2/catalyst and electrolyte interface and validly reduces the charge recombination from TiO2to the oxidized catalyst. © 2016 Science Press
