The crystal structure, optical properties, surface and bulk morphology have been characterised using various tools like X-ray diffraction (XRD), UV visible spectroscopy, Fourier transform infrared spectroscopy, transmission electron microscope (TEM) and scanning electron microscope (SEM). Cubic, spheres and porous like morphology of SnO2 photocatalyst was successfully confirmed using SEM micrographs and TEM. In addition to this the photocatalytic activity was evaluated towards the degradation of methylene blue dye solution. SnO2 photocatalyst annealed at 600 degrees C exhibits excellent photocatalytic efficiency which may be attributed to the unique morphology, high crystalline nature and charge separation. The photocatalyst efficiency was further tested towards the concentration of dye, catalyst dosage and pH of the dye. The involvement of center dot OH in the photocatalytic reaction was evidenced using trapping experiment by employing different scavengers. The photocatalyst was moderately active, stable upto its fifth usage and stability of the photocatalyst before and after the photocatalytic reaction was also been studied using XRD and SEM.</style></abstract><issue><style face="normal" font="default" size="100%">14</style></issue><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">0.832</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Prakash, K.</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">Manchanda, S.</style></author></secondary-authors><tertiary-authors><author><style face="normal" font="default" size="100%">Sudhakar, V.</style></author></tertiary-authors><subsidiary-authors><author><style face="normal" font="default" size="100%">Sharma, N.</style></author><author><style face="normal" font="default" size="100%">Sankar, M.</style></author><author><style face="normal" font="default" size="100%">Krishnamoorthy, K.</style></author></subsidiary-authors></contributors><titles><title><style face="normal" font="default" size="100%">Facile synthesis of β-functionalized “push-pull” Zn(II) porphyrins for DSSC applications</style></title><secondary-title><style face="normal" font="default" size="100%">Dyes and Pigments</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">charge transfer</style></keyword><keyword><style  face="normal" font="default" size="100%">Conduction Bands</style></keyword><keyword><style  face="normal" font="default" size="100%">Cyanoacetic Acid</style></keyword><keyword><style  face="normal" font="default" size="100%">Electrolytes</style></keyword><keyword><style  face="normal" font="default" size="100%">Floorescence</style></keyword><keyword><style  face="normal" font="default" size="100%">Redox Reaction</style></keyword><keyword><style  face="normal" font="default" size="100%">zinc compounds</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2017</style></year><pub-dates><date><style  face="normal" font="default" size="100%">DEC</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">147</style></volume><pages><style face="normal" font="default" size="100%">56-66</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;Three new β-substituted “push-pull” Zn(II) porphyrin dyes with various electron donors at meso-positions and cyanoacetic acid as acceptor at β-position have been designed and synthesized. These porphyrins have been characterized by UV-Vis, Fluorescence, 1H NMR and 13C NMR spectroscopic techniques and cyclic voltammetric studies. The Soret and Q band of Zn(II) porphyrin dyes were found to be red-shifted (30–35 nm) as compared to ZnTPP. The fluorescence quenching and the decrement in quantum yield and lifetime suggest intramolecular charge transfer from donor to acceptor. Zn porphyrins exhibited anodic shift in their first redox potentials (0.03–0.11 V) as compared to ZnTPP. The HOMO-LUMO energy levels of Zn porphyrin dyes were compared with the conduction band of TiO2 and the electrolyte I−/I3 −. The HOMO levels of all the dyes are sufficiently higher than the energy level of electrolyte I−/I3 − and LUMO levels significantly lower than the conduction band of TiO2 which reflect the feasibility of facile electron-transfer. ZnT(Mes)P(CN-COOH) has been co-sensitized with N719 dye to further improve the PCE efficiency. These dyes displayed power conversion efficiency (PCE) of η = 1.72–3.13% where co-sensitized ZnT(Mes)P(CN-COOH) (N719) dye demonstrated maximum PCE efficiency up to 5.35%, with a Jsc of 11.8 mA cm−2, a Voc of 630 mV and a fill factor (FF) of 72% due to better light harvesting capacity.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Journal Article</style></work-type><custom3><style face="normal" font="default" size="100%">&lt;p&gt;Foreign&lt;/p&gt;</style></custom3><custom4><style face="normal" font="default" size="100%">&lt;p&gt;4.055&lt;/p&gt;</style></custom4></record></records></xml>
