Journal ArticleDOI
High-capacity hydrogen storage in lithium and sodium amidoboranes
Zhitao Xiong,Chaw-Keong Yong,Guotao Wu,Ping Chen,Wendy J. Shaw,Abhi Karkamkar,Tom Autrey,Martin O. Jones,Simon R. Johnson,Peter P. Edwards,William I. F. David +10 more
TL;DR: The low-temperature release of a large amount of hydrogen is significant and provides the potential to fulfil many of the principal criteria required for an on-board hydrogen store.
Journal ArticleDOI

Camp,Eun Seon Cho,Hiroyasu Furukawa,Hiroyasu Furukawa,Maciej Haranczyk,Martin Head-Gordon,Martin Head-Gordon,Sohee Jeong,Abhi Karkamkar,Di Jia Liu,Jeffrey R. Long,Jeffrey R. Long,Katie R. Meihaus,Iffat Nayyar,Roman Nazarov,Donald J. Siegel,Vitalie Stavila,Jeffrey J. Urban,Srimukh Prasad Veccham,Brandon C. Wood +26 more
TL;DR: An overview of the major known and proposed strategies for hydrogen adsorbents is provided, with the aim of guiding ongoing research as well as future new storage concepts.
Journal ArticleDOI
Determination of Structure and Phase Transition of Light Element Nanocomposites in Mesoporous Silica: Case study of NH3BH3 in MCM-41
TL;DR: In this article, the authors used atomic pair distribution function (PDF) analysis of synchrotron X-ray powder diffraction data to follow the structural evolution of molecular crystal ammonia borane (AB) embedded within MCM-41 at temperatures ranging from 80 to 300 K.
Journal ArticleDOI
Solid-state hydrogen rich boron–nitrogen compounds for energy storage
TL;DR: This review highlights developments in synthesis of ammonia borane and its derivatives over the last 80 years and identifies the key distinctions between homopolar and heteropolar H2 release.
Journal ArticleDOI
Role of Calcination Temperature on the Hydrotalcite Derived MgO–Al2O3 in Converting Ethanol to Butanol
Karthikeyan K. Ramasamy,Michel J. Gray,Heather Job,Daniel M. Santosa,Xiaohong Shari Li,Arun Devaraj,Abhi Karkamkar,Yong Wang,Yong Wang +8 more
TL;DR: In this article, the characteristics of the hydrotalcite material treated between catalytically relevant temperatures 450 and 800°C have been studied with respect to the physical, chemical, and structural properties and compared with catalytic activity testing.
