Design and Control of Dynamical Quantum Processes in Ortho-para H2 Conversion on Surfaces -from Atomic-Scale Understanding to Meter-Scale Application-

Abstract


We present here a novel, cost-effective method for increasing and controlling the ortho-para H2 (o-p H2) conversion yield. First, we invoke two processes derived from fundamental, surface science insights, based on the effect of molecular orientation on the hydrogen-solid surface reaction, i.e., dynamical quantum filtering and steering, and apply them to enhance the o-p H2 conversion yield. Second, we find an important factor that can significantly influence the yield i.e., inhomogeneity of spin density distribution. This factor gives us a promising possibility to increase the yield and to find the best catalyst e.g., design of materials that can function as catalysts for the o-p H2 conversion.
