采用有机p/n双层光电极从H+产生H2，其中n型富勒烯（C60）与p型酞菁锌（ZnPc）结合使用。当Pt催化剂负载于C60表面时，在Pt负载的C60表面上通过析氢成功地产生了光电阴极电流.光电流的作用光谱测量结果的基础上，H2的演变似乎是在整个可见光波长范围内的诱导<750 nm。特别是ZnPc/C60双层膜的可见光吸收有效地促进了载流子的产生，从而通过减少双层膜内一系列光物理事件产生的功率，导致C60表面的H2析出。
A photoelectrode featuring an organic p/n bilayer was used to generate H2from H+, where n-type fullerene (C60) was used in combination with p-type zinc phthalocyanine (ZnPc). When a Pt catalyst was loaded on the surface of C60in the organo-photoelectrode, a photocathodic current was successfully generated via H2evolution at the Pt-coated C60surface. On the basis of the results of action spectral measurements for photocurrent, the H2evolution appeared to be induced over the entire visible-light wavelength range of <750 nm. In particular, the visible-light absorption of ZnPc/C60bilayer efficiently contributed to carrier generation, consequently leading to the H2evolution at the C60surface via reducing power generated through a series of photophysical events within the bilayer.
