Synthesis of TiO2 Nanotube Arrays for Hydrogen Production from Photo-Assisted Water Splitting Reaction

Kawde A.Y., Vats A., Shende R.V., Puszynski J.A., South Dakota School of Mines & Technology, US

This study focuses on the synthesis of TiO2 nanotube arrays and its application for hydrogen generation from photo-assisted water-splitting reaction. In the synthesis approach, an nt-TiO2/Ti/nt-TiO2 structure was synthesized using electrochemical anodization in fluorine (F-) [...]

Strain effect on the hydrogen storage capacity of graphite oxide

Kim J., Seo M., Kim J., Kang S., Seoul National Univ., KR

Among clean fuel alternatives hydrogen is one of the most attractive fuels due to its abundance, easy synthesis, and non-polluting nature when used in fuel cells. Recently carbon-based materials which have high specific surface area [...]

Investigation of a short stack PEM electrolyzer based on a nanosized IrO2 anode electrocatalyst

Di Blasi A., Siracusano S., Baglio V., Briguglio N., Stassi A., Antonucci V., Aricò A.S., CNR ITAE, IT

Electrolysis systems based on PEMs have a number of advantages in comparison to the traditional alkaline electrolyzers, such as ecological cleanliness, considerably smaller mass–volume characteristics and, essentially, a high degree of gases purity. The main [...]

Nguyen K.C., Chung L.T., THLLC Joint Stock Company, VN

A hydroelectric fuel cell system is designed for stand-alone household generator to meet the need of home electricity behind national electrical network in Vietnam. The energy system utilizes water to generate H2 by the reduction [...]

Carbon-supported platinum and nickel nanoparticles for CO capture in hydrogen fuel cells

J. D. Durbin D., J. Fermin D., Plana D., J. D. Durbin D., J. Fermin D., Malardier-Jugroot C., Royal Military College of Canada, CA

Fuel cells are electrochemical cells that convert chemical energy into electrical energy with efficiencies up to 80%; they are a promising potential replacement for internal combustion engines in automobiles. However, carbon monoxide poisoning of the [...]

Optimization study of Supercapacitor electrode material composition and thickness for enhanced performance of the Supercapacitor

Ranade A.P., Jung D.Y., Sammakia B.G., Eilertsen T., Davis T., Binghamton University, US

A prototype electrode was constructed to verify the optimization of composition of materials for the supercapacitors. Surface area analysis and SEM images were used initially to select the most appropriate active carbon from a group [...]

(Au, Ag, Ti)-SiO2 Core-Shell Nanoparticles Based Polymer Nanodielectrics for Energy Storage Applications

Badi N., Singh R., Bensaoula A., Rittikulsittichai S., Thanasarakhan T., Randall Lee T., University of Houston, US

This paper addresses materials and processes for energy storage in high k embedded capacitors using metal nanoparticles coated and uncoated SiO2 shells (M@SiO2, where M = Au, Ag, and Ti)) and high K polymer matrices [...]

Overview of four energy storage techniques

Chukwubuikem C., University of Cape Town, ZA

Abstract: Renewable Energy has gained a significant attention in recent years due to high energy cost and adverse environmental impacts of conventional fossil fuels. One of the major challenges for the renewable energy systems remains [...]

Microstructures and electrochemical properties of Si-Ni based alloys

Song J-J, Inje University, KR

In this work, Si-Ni-Al and Si-Ni-Cu-Al alloy ribbons were fabricated by a rapid solidification process to minimize the effect of the volume change of silicon particles. Thin ribbons with thicknesses of 10~20μm were fabricated by [...]
