چکیده انگلیسی
An organic p-n bilayer photocatalyst, comprising a perylene derivative (PTCBI, n-type) and cobalt phthalocyanine (CoPc, n-type), is utilized for the oxidative formation of molecular hydrogen (H2) from a borane-ammonia complex (NH3BH3, AB). The formation of H2 occurs photocatalytically at the surface of CoPc in the organo-bilayer, along with the reduction of O2 by a reducing power generated at PTCBI. The mechanism to illustrate the H2-formation from AB by the organo-photocatalyst may be different from that of the conventional photocatalysis by inorganic semiconductors. To further understand the mechanism of H2-formation, photoelectrochemistry is further investigated using the PTCBI/CoPc bilayer as a photoanode. Considering the resulting faradaic efficiency for H2-formation, at least two possible equations have to be suggested: BH3OHâ (intermediate)â¯+â¯3OHââ¯ââ¯BO2ââ¯+â¯3/2H2â¯+â¯2H2Oâ¯+â¯3eâ and BH3OHâ (intermediate)â¯+â¯2OHââ¯ââ¯BO2ââ¯+â¯2H2â¯+â¯H2Oâ¯+â¯2eâ.
