Photoionization of N-alkyphenothiazines in mesoporous metal silicoaluminophosphate molecular sieves

Article Abstract:

The photoionization of N-alkylphenothiazines (PC(sub n) where n=1,3,6,10, and 16) in mesoporous silicoaluminophosphate (UHM-3) and transition metal-substituted silicoaluminophosphate (MUHM-3 where M=Cu,Ni,Cr,and Mn) molecular sieves by electron spin resonance with ultraviolet irradiation at room temperature is studied. The effect of the ratio of Si/Al, the nature of the transition metal, and the concentration of the metal on the photoyield is studied.

Synthesis of mesoporous aluminophosphate (AIPO) and investigation of zirconium incorporation into mesoporous AIPOs

Article Abstract:

Mesoporous aluminophosphate materials with variable amounts of zirconium were synthesized at room temperature using a nonionic surfactant tri-block copolymer as the structure-directing agent. Zirconia-based materials have wide applications in the field of catalysis in dehydration, hydrogenation, and hydroxylation reactions.

Photoinduced charge separation of methylphenothiazine in microporous metal silicoaluminophosphate M-SAPO-n (M = Cr, Fe, Mn, n= 5, 8, 11) materials

Article Abstract:

Chromium containing SAPO materials exhibited the highest photoyield among the Cr, Fe, and Mn transition metals ions studied. The photoionization efficiency was found to depend on the nature of the metal ion, the concentration of the metal ion, and also on the pore size of the microporous SAPO material used.
