抄録

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.
