Photocatalytic Systems Based on Acridine Salts Derivatives
摘要:
The possibility of 10-methyl-9-phenylacridine iodide usage as a photocatalyst in the process of molecular hydrogen evolution in various aprotic solvents has been shown. A possible process scheme has been suggested. The influence of the acid nature and its concentration on the efficiency of the photocatalytic process has been revealed. It has been shown that the highest amount of molecular hydrogen is formed in presence of acids with intermediate pK.

Change happens: Acridine–carbon nanotube nanohybrids were built (see figure) and their photoinducedelectron‐transfer properties investigated, showing variable behaviour depending on the acridine partner.
salt 9-phenyl-10-methylacridinium iodide for hydrogen evolution reaction. A controlled potential electrolysis experiment in present 9-phenyl-10-methylacridinium iodide with a simultaneous gas chromatographic analysis confirmed the catalytic production of molecular hydrogen. The behavior of the catalytic wave is typical for a “total catalysis”. A mechanism involving initial reduction of PhAcr+/PhAcr
