Reduced Graphene Oxide - Molybdenum Disulfide Aerogel Nanocomposite Electrodes for Supercapacitors
Aydınlı, Alptekin; Doğan, Öznur; Koylan, Serkan; Bat, Erhan; Ünalan, Hüsnü Emrah (null; 2018-11-25)
Supercapacitors have attracted extensive attention for their high specific power and moderate energy densities. Nanoscale structure and high surface area are the two main requirements for a supercapacitor electrode with high performance. We report on the fabrication and electrochemical characterization of hybrid aerogel nanocomposite supercapacitor electrodes composed of reduced graphene oxide and molybdenum disulfide nanosheets on nickel foams. Graphene oxide was produced using Tour Method. Reduced graphen...
Double‐decker lutetium and europium phthalocyanine composites with reduced graphene oxide as supercapacitor electrode materials
YABAŞ, EBRU; Biçer, Emre; Durukan, Mete Batuhan; Keskin, Deniz; Ünalan, Hüsnü Emrah (2022-12-01)
© 2022 Elsevier B.V.Double‐decker phthalocyanines were synthesized by a classical method with phthalonitrile and lanthanide metal salts, europium and lutetium acetate. Non-covalent double-decker phthalocyanine-reduced graphene oxide (MPc2/rGO) composites were then prepared by simple sonication method. All the phthalocyanines were peripheral tetrasubstituted 5-(3-pyridyl)-1,3,4-oxadiazole. Following spectroscopic and morphological characterisation, fabricated composites were subjected to detailed electrochem...
Enhanced photocurrent in PbSe nanorod-quantum dot bulk nano-heterojunction solar cells
Hacıefendioğlu, Tuğba; Balıkoğlu, Bensu; Aydın, Firdevs; Kolay, İrem; Öztürk, İbrahim; Asil, Demet (2021-01-01)
Owing to their remarkable multiple exciton generation (MEG) yield, PbSe nanorods (NRs) have been considered as one of the most promising materials to overcome the Shockley–Queisser limit. Unfortunately, assessing the direct role of the PbSe NRs in solar cell designs has been challenging due to their unoptimized film microstructure and poor performances. Here we devise a cell architecture that overcomes these limitations by inserting an electron blocking quantum dot (QD) layer to the NR/metal interface. Furt...
Efficient Ceria-Supported Rhodium Nanoparticles as an Electrocatalyst for Hydrogen Evolution
Akbayrak, Merve; Önal, Ahmet Muhtar (The Electrochemical Society, 2019-12-13)
Rh-0/CeO2 catalystwas prepared by the reduction of Rh+3 ions on CeO2 surface and characterized by transmission electron microscopy, inductively coupled plasma optical emission spectrometry, X-ray photoelectron spectroscopy and powder X-ray diffractometry techniques. To investigate its electrocatalytic activity for H-2 evolution reaction, a glassy carbon electrode (GCE) was modified with Rh-0/CeO2. The modified electrode was found to exhibit a high electrocatalytic activity (turnover frequency (TOF): 1.56 s(...
Enhanced supercapacitors from hierarchical carbon nanotube and nanohorn architectures
Hiralal, Pritesh; Wang, Haolan; Ünalan, Hüsnü Emrah; Liu, Yinglin; Rouvala, Markku; Wei, Di; Andrew, Piers; Amaratunga, Gehan A. J. (2011-01-01)
Supercapacitors fill the power and energy gap between electrolytic capacitors and batteries. The energy density for commercial supercapacitors is currently limited to similar to 5 Wh kg similar to 1. Enhancing the energy and power density of supercapacitors is of great interest as it would open up a much wider range of applications. In this work, thin film supercapacitors made of random networks of single-walled carbon nanotubes (SWNTs) were enhanced by the use of carbon nanoparticles of a size ideal to fil...
