New Method to Enhance the ortho-para H2 Conversion by using Dynamical Quantum Filtering Effect and Steric Effect

We introduce a new method to enhance the orthohydrogen-parahydrogen (o-p H2) conversion yield /rate of a H2 interacting with a solid surface. This method consists of two steps. The first step involves the dynamical quantum filtering (DQF) process, and the second step relies on the steric effect on o-p H2 conversion. The purpose of the DQF process is to align the rotation of free rotating o-H2 such that we have only H2 in helicopter-like rotational states or H2 in cartwheel-like rotational states. In the second process, we bring these aligned o-H2 close to a catalyst surface (e.g., metal oxide surface). Based on the steric effect, o-H2 that has a cartwheel-like rotation will be converted to p-H2 with high rate.
