Synthesis, characterization, and photocatalytic disinfection studies of porphyrin dimer/TiO2-based photocatalyst

In this research, we synthesized a novel panchromatic absorption dimer porphyrin and designed a dimer molecule with maximum absorption in the visible and NIR regions. The work was followed and monitored by its photocatalytic function with anatase TiO2 and brookite-rutile TiO2, and preliminarily compared and tested its photocatalytic disinfection of gram-negative bacteria Escherichia coli (E. coli) in visible light conditions toward the potential of future studies. The finding results were compared with the bare anatase TiO2 and brookite-rutile TiO2. The prepared structure of molecules was confirmed by SEM, EDS, XRD, XPS, and solid-state diffuse reflectance spectral studies.

Synthesis of novel panchromatic porphyrin-squaraine dye and application towards TiO2 combined photocatalysis

Here with, a porphyrin-squaraine-based panchromatic sensitizer was designed, synthesized perfectly and confirmed by its spectral analysis. SP-TBU showed a wide energy absorption in the visible and NIR region, which is very important criteria for photocatalytic activity studies. With this dye, a new TiO2-porphyrin catalyst was prepared and studied using SEM, TEM, UV–vis diffused reflectance spectra, FT-IR spectroscopy, XPS, and EDS analyses. The photocatalytic activity for methylene blue degradation under visible light was studied and compared with the bare TiO2 and (4,4′,4″,4?-(porphine-5,10,15,20-tetrayl)tetrakis(benzoic acid) with TiO2 (TCPP-TiO2) taken with and without the addition of H2O2. The order of the photocatalytic activity performance was TiO2 2 2. The fast and efficient activity of SP-TBU-TiO2 was due to its broad absorption ability. This is the first report of panchromatic TiO2-porphyrin-squarine photocatalysis.

Synthesis of porphyrin sensitizers with a thiazole group as an efficient π-spacer: Potential application in dye-sensitized solar cells

Herein, we report porphyrin sensitizers for DSSCs, coded CNU-OC8 and CNU-TBU, which were synthesized using a donor-π-bridge-acceptor approach. The porphyrin sensitizers were subjected to electrochemical experiments to study their electron distribution, in

Synthesis and Characterization of Donor-π-Acceptor-Based Porphyrin Sensitizers: Potential Application of Dye-Sensitized Solar Cells

New porphyrin sensitizers based on donor-π-acceptor (D-π-A) approach have been designed, synthesized, characterized by various spectroscopic techniques and their photovoltaic properties explored. N,N′-Diphenylamine acts as donor, the porphyrin is the π-spacer, and either carboxylic acid or cyanoacryclic acid acts as acceptor. All compounds were characterized by using 1H-NMR spectroscopy, ESI-MS, UV-visible emission spectroscopies as well as electrochemical methods. The presence of aromatic groups between porphyrin π-plane and acceptor group push the absorption of both Soret and Q-bands of porphyrin towards the red region. The electrochemical properties suggests that LUMO of these sensitizers above the TiO2 conduction band. Finally, the device was fabricated using liquid redox electrolyte (I-/I3-) and its efficiency was compared with that of a leading sensitizer. Rooftop ready: New porphyrin sensitizers based on a donor-π-acceptor approach have been designed, synthesized, and characterized by various spectroscopic techniques and their photovoltaic properties were explored. The electrochemical properties suggest that the LUMO of these sensitizers is above the TiO2 conduction band. The sensitizer HYD4-OC8, has shown an overall conversion efficiency of 9.25 %, whereas the standard sensitizer YD2-O-C8, has shown 9.40 %.

Synthesis and characterization of porphyrin sensitizers with various electron-donating substituents for highly efficient dye-sensitized solar cells

A series of porphyrin dyes with an electron-donating group (EDG) attached at a meso-position (YD1-YD8) have been designed and synthesized for use as sensitizers in dye-sensitized solar cells (DSSC). The nature of the EDG exerts a significant influence on the spectral, electrochemical and photovoltaic properties of these sensitizers. Absorption spectra of porphyrins having an amino group show broadened Soret band and red-shifted Q bands with respect to those of reference porphyrin YD0. This phenomenon is more pronounced for porphyrins YD7 and YD8 that have a π-conjugated triphenylamine at the meso-position opposite the anchoring group. Upon introduction of an EDG at the meso-position, the potential for the first oxidation alters significantly to the negative whereas that for the first reduction changes inappreciably, indicating a decreased HOMO-LUMO gap. Results of density-functional theory (DFT) calculations support the spectroelectrochemical data for a delocalization of charge between the porphyrin ring and the amino group in the first oxidative state of diarylamino-substituted porphyrins YD1-YD4, which exhibit superior photovoltaic performance among all porphyrins under investigation. With long-chain alkyl groups on the diarylamino substituent, YD2 shows the best cell performance with JSC = 13.4 mA cm-2, VOC = 0.71 V, and FF = 0.69, giving an overall efficiency 6.6% of power conversion under simulated one-sun AM1.5 illumination.
