'Perovskitization'-Assisted Electrochemical Reduction of Solid TiO2 in Molten CaCl2

摘要

The present inability to increase on-board hydrogen storage beyond 6 wt % of the storage materials and/or devices suggests that a longer time is needed before commercially viable hydrogen-powered vehicles join the battle against global warming. This situation would not be quite so constraining, however, if car manufacturers could replace steel components by titanium ones as both are equally strong but titanium is about 40 % lighter (and more corrosion resistant). A lighter titanium car would then allow an additional load capacity for the heavy hydrogen-storage system. However, titanium (
