30. Electric field enhanced hydrogen storage on polarizable materials substrates

Abstract

Using density functional theory, we show that an applied electric field can substantially improve the hydrogen storage properties of polarizable substrates. This new concept is demonstrated by adsorbing a layer of hydrogen molecules on a number of nanomaterials. When one layer of [H.sub.2] molecules is adsorbed on a BN sheet, the binding energy per [H.sub.2] molecule increases from 0.03 eV/[H.sub.2] in the field-free case to 0.14 eV/[H.sub.2] in the presence of an electric field of 0.045 a.u. The corresponding gravimetric density of 7.5 wt% is consistent with the 6 wt% system target set by Department of Energy for 2010. The strength of the electric field can be reduced if the substrate is more polarizable. For example, a hydrogen adsorption energy of 0.14 eV/[H.sub.2] can be achieved by applying an electric field of 0.03 a.u. on an AIN substrate, 0.006 a.u. on a silsesquioxane molecule, and 0.007 a.u. on a silsesquioxane sheet. Thus, application of an electric field to a polarizable substrate provides a novel way to store hydrogen; once the applied electric field is removed, the stored Hz molecules can be easily released, thus making storage reversible with fast kinetics. In addition, we show that materials with rich low-coordinated nonmetal anions are highly polarizable and can serve as a guide in the design of new hydrogen storage materials. energetics [ kinetics | nanomaterials | polarization | reversibility www.pnas.org/cgi/doi/10.1073/pnas.0905571107

Abstract

A well-developed technique, based upon a combined experimental and phenomenological modeling approach, has been adopted for the measurement of nitric oxide (NO) emissions in a diesel engine exhaust under transient engine operation. The dynamic behavior of the chemiluminescent analyzer used for the measurement of NO emissions is characterized by a single gas diffusion model followed by three perfect gas-mixing models. The response of the analyzer is obtained using a computer-controlled transient NO emission simulator, which randomly generates a square-pulse train of NO gas and concurrently measures its signal output. Signal prediction and reconstruction analysis were performed, which has demonstrated the predictive and reconstructive capabilities of the phenomenological analyzer model. On-line nitric oxide emission measurements were obtained in a computer-controlled dynamic engine test bed having three different control modes and fuel injection timing settings. The results have shown that the transient nitric oxide concentration is very sensitive to the engine operating condition prior to the transients as well to the amount of fuel injected into the combustion chamber at the start of the transient operation.
