J. Am. Chem. Soc., ASAP Article 10.1021/ja071323z S0002-7863(07)01323-6 Web Release Date: May 9, 2007 Copyright © 2007 American Chemical Society Magnesium Nanowires: Enhanced Kinetics for Hydrogen Absorption and Desorption Weiyang Li, Chunsheng Li, Hua Ma, and Jun Chen* Institute of New Energy Material Chemistry, Nankai University, Tianjin 300071, People's Republic of China chenabc@nankai.edu.cn Received February 25, 2007 Abstract: Mg nanowires with the diameters of 30-50 nm, 80-100 nm, and 150-170 nm, which were prepared via a vapor-transport method, exhibited enhanced kinetics for hydrogen absorption/desorption. The present results clearly show that thinner Mg/MgH2 nanowires have a much lower desorption energy than that of thicker nanowires or bulk Mg/MgH2, indicating that changes in kinetics and thermodynamics are expected if the diameters of the nanowires are thinner than 30 nm.
