Hydrogen Absorption Property of Pd-Doped Porous Materials

چکیده
In electrochemical loading of Pd with deuterium, it has been known that attaining a D/Pd value larger than 0.88 is necessary for triggering excess heat effects [1]. It has been reported by Arata and Zhang that the heat arising from D-D nuclear fusion reaction in solid is observed simply by pressurizing nano-Pd/ZrO2 system with deuterium gas [2]. It seems that nano-scale Pd particles absorb more hydrogen than Pd bulk and use of nano-Pd is advantageous to induce anomalous heat effect in gas loading experiments.

Comparison of doped combination zirconium-tungsten, zirconium- molybdenum and molybdenum-tungsten on single-wall vanadium oxide nanotube in hydrogen gas adsorption
In this study, doped vanadium oxide nanotubes were evaluated using different software to study the absorption of hydrogen gas. Vanadium oxide nanotubes are one of the options for absorption and storage hydrogen gas. In this research study for the first time, the Monte Carlo simulation was used to investigate the hydrogen gas absorption behavior in molybdenum-tungsten, molybdenum-zirconium and z...
متن کاملبررسی قابلیت جذب هیدروژن در ماده مرکب نانوساختار SBA-16-Pd
The purpose of this work was to study the hydrogen adsorption on the surface of mesoporous materials based on silica (SBA-16) modified with palladium via temperature. Since mesoporous silica materials have a high specific surface area, and the ordered mesoporous size of 2-10nm, they are suitable for adsorption and storage of hydrogen. SBA-16 is suitable for this purpose due to its cubic crystal...

متن کاملInteraction of Hydrogen with Au Modified by Pd and Rh in View of Electrochemical Applications
Hydrogen interaction with bimetallic Au(Pd) and Au(Rh) systems are studied with the density functional theory (DFT)-based periodic approach. Several bimetallic configurations with varying concentrations of Pd and Rh atoms in the under layer of a gold surface(111) were considered. The reactivity of the doped Au(111) toward hydrogen adsorption and absorption was related to the property modificati...
متن کاملDetermination of thermodynamic parameters of hydrogen permeation of palladium membrane for considering the effect of stainless steel support
A palladium composite membrane was prepared by electroless plating on oxidized porous stainless steel support (ox-PSS). Hydrogen permeation flux through this composite membrane was measured in the temperature range of 574-674K and the pressure difference of two sides of membrane up to 90kPa. A simplified resistance model was employed to analyze the permeation behavior of hydrogen through Pd/ox-...
