Hydrolysis of Hydrazine Borane for Chemical Hydrogen Storage by Highly Efficient Poly(N-vinyl-2-pyrrolidone)-protected Rhodium Nanoparticles

Bayram Abay, Nihat Tunç and Murat Rakap
The employment of poly(N-vinyl-2-pyrrolidone)-protected rhodium nanoparticles (3.8 ± 1.2 nm) as highly efficient catalysts in the hydrolysis of hydrazine borane for hydrogen generation is reported. The catalyst is prepared by reduction of rhodium metal ion in ethanol/water mixture by an alcohol reduction method and characterized by TEM analysis, UV-Vis spectroscopy, and X-ray photoelectron spectroscopy.

Surface Modification Efficiency of Titanium-based Particles with an Alkyl Phosphate

Igor Lopes Soares, Elton Jorge da Rocha Rodrigues, Taís Nascimento dos Santos, Emerson Oliveira da Silva and Maria Inês Bruno Tavares
This article reports the efficiency of surface modification of titanium particles based on an alkyl phosphate. Different techniques were used to evaluate the behavior of the samples after modification, in terms of better particle dispersion tendency in response to type and quantity of modifier incorporation (TiO2 anatase in crystalline form).
