(2020) Solğun, Derya Güngördü; Horoz, Sabit; Agırtas, Mehmet Salıh
Bu çalışmada, başlangıç materyali olarak non periferik bir ftalonitril bileşiği hazırlanmıştır. Daha sonra bu 3,4- dimetoksifentoksi sübstitüentli non periferal ftalonitril bileşiği, Co, Zn ve Cu tuzları ile reaksiyona sokuldu. Kolay ve pratik bir metot kullanılarak non periferal ftalosiyanin bileşikleri hazırlandı. Çinko ftalosiyanin bileşiğinin floresan spektrumları tetrahidrofuran içinde ölçüldü. Agregasyon çalışmaları, non periferal ftalosiyanin bileşikleri için incelenen konsantrasyon aralığında lambert-beer yasasına uyum göstermiştir. Termogravimetrik (TG) analizler bileşiklerin kararlı olduğunu gösterdi. Bu ftalosiyanin bileşiklerinin fotovoltaik performansı akım yoğunluk voltajı (J-V) olarak ölçüldü. Hesaplanan güç dönüşüm etkileri, bu bileşiklerin, boyaya duyarlı güneş pili (DSSC) yapıları için kullanılma potansiyeline sahip olduğunu göstermiştir.

(Taylor & Francis inc, 2020) Cabir, Beyza; Yildiko, Umit; Agirtas, Mehmet Salih; Horoz, Sabit
In this study, 4-((2R, 3S)-2, 3, 4-trihydroxybutoxy) phthalonitrile was synthesized and characterized as starting material. This new starting material reacts with cobalt and copper metal salts to obtain metallophthalocyanine complexes. The electronic absorption of cobalt and copper phthalocyanine compounds in different concentrations of THF was investigated. In addition, the solubility and absorption of the compounds in different solvents were investigated. Density functional theory was also performed to support the relevant experimental results of the synthesized copper and cobalt center atomic compound. The photovoltaic performance of compounds was measured as current density-voltage (J-V).
High Hydrogen Production Rate From Potassium Borohydride Hydrolysis With an Efficient Catalyst: Cnt@ru(0)
(Elsevier Science inc, 2022) Keskin, M. Salih; Agirtas, Mehmet Salih; Baytar, Orhan; Izgi, M. Sait; Sahin, Omer; Horoz, Sabit
We describe the production and catalytic activity of a carbon nanotube supported-Ru(0) (CNT@Ru(0)) catalyst. For the first time, the produced CNT@Ru(0) catalyst is used to achieve the greatest hydrogen production rate from potassium borohydride (KBH4) hydrolysis. The produced CNT@ Ru(0) catalyst shows promise in the creation of hydrogen from the degradation of KBH4. The hydrogen generation rate of CNT@Ru(0) is determined to be 86,264.85 mL min(-1) can with a low activation energy of 30.18 kJ mol(-1). CNTs are potential support for distributing metal catalysts, according to the current work. Furthermore, structural, morphological, and elemental characteristics of the produced CNT@Ru(0) catalyst are investigated.
Synthesis of Novel Tetra (4-Tritylphenoxy) Substituted Metallophthalocyanines and Investigation of Their Aggregation, Photovoltaic, Solar Cell Properties
(Taylor & Francis inc, 2018) Solgun, Derya Gungordu; Horoz, Sabit; Agirtas, Mehmet Salih
4-(4-tritylphenoxy) phthalonitrile was synthesized and characterized. Copper, zinc and cobalt phthalocyanines were obtained by reaction of 4-(4-tritylphenoxy)phthalonitrile with CuCl2, ZnCl2, CoCl2 metal salts. New compounds were characterized by using electronic absorption, nuclear magnetic resonance spectroscopy, infrared. The aggregation investigation for phthalocyanine complexes carried out in different concentrations tetrahydrofuran. Copper, cobalt and zinc phthalocyanines were used as sensitizers in dye-sensitized solar cell structures (DSSC) by growing on TiO2 coated on FTO (Fluorine doped Tin Oxide) conductive glass substrates. Current density (J) versus voltage (V) measurements were applied to investigate the photovoltaic properties of the synthesized complexes. The calculated power conversion efficiencies (%) of the complexes using the obtained current density (J) versus voltage (V) curves show that these devices can be used as promising sensitizers in solar cell applications.
