A Full‐Spectrum Visible‐Light‐Responsive Organophotocatalyst Film for Removal of Trimethylamine

Photocatalytic decomposition of N-methyl-2-pyrrolidone, aldehydes, and thiol by biphase and p/n junction-like organic semiconductor composite nanoparticles responsive to nearly full spectrum of visible light

“…4). During NMP diffusion in water, recrystallization and phase separation took place as a result of a weak interaction between C 60 and AlPcCl in the NMP solution [13], after which nucleated particles of C 60 and AlPc were formed. Subsequent particle growth occurred through the aggregation of not only the homologous but also the heterologous nucleated particles, where the aggregation of the latter was induced because of the opposite electrical charge they possessed.…”

“…Furthermore, the p/n junction has also been shown to perform the functions of a laser-induced reflection device on the basis of photon-induced charge separation without an electrode [12]. On the basis of these reports, we applied an organic n/p bilayer of a perylene derivative and metal-free phthalocyanine (H 2 Pc) coated on a Nafion membrane for the photodegradation of an organic pollutant [13], wherein the organophotocatalyst was highly responsive to visible light. We further continued organophotocatalyst research in order to decrease its fabrication cost for practical use and developed a nanoparticulate organic composite [14].…”

Study of Co-deposition Photoelectrode of Perylene Derivative and Phthalocyanine in Comparison with Its Bilayer Focusing on Charge Transfer Complex and Kinetic Analysis

“…Stable organic semiconductor composed of p/n junction responsive to whole visible light was operated and utilized not only for photovoltaic (OPV), 1-10 but also photocatalyst. [11][12][13][14][15][16][17][18][19][20] For the design of efficient OSM photocatalyst, material selection for p-type and n-type is different from photovoltaic devices. In the case of photocatalyst, p-type is oxidation part and phthalocyanine (Pc) exhibited as a co-catalyst site.…”

Synthesis and characterization of Biphasic Vanadyl phthalocyanine and C₆₀ composite nanoparticles through a reprecipitation process

“…[3] Tang first reported in 1986 of a heterojunction composed of bilayer organic solar cell composed of CuPc and a perylene derivative. [4] We have previously studied the photoelectrochemistry of organic n/p bilayer of a perylene derivative (3,4,9,10-perylenetetracarboxyl-bisbenimidazole, PTCBI) or fullerene (C 60 ) and metal-free Pc's (H 2 Pc) in water phase, [5][6][7][8][9][10][11][12][13] wherein the evolution of O 2 from water was found to occur along with hole conduction through the p-type layer under visible light irradiation. [8] The studies indicate that the photoinduced redox reaction occur catalytically on the semiconductor surfaces and that the organic bilayer of the p/n junction lead to an efficient generation of photocurrent in comparison with the single layers of the Schottky junction.…”
