TL;DR

This paper introduces a molecular sieve utilizing a carbon nanotube junction and C60 to selectively filter hydrogen based on its high compressibility, effectively blocking neon and argon.

Contribution

The study presents a novel hydrogen sieve mechanism exploiting high compressibility, combining carbon nanotube junctions and C60 molecules for selective permeation.

Findings

Hydrogen can be selectively sieved using the proposed molecular structure.

The sieve effectively blocks neon and argon while allowing hydrogen passage.

The mechanism relies on hydrogen's unique high compressibility.

Abstract

A molecular sieve for hydrogen is presented based on a carbon nanotube intramolecular junction and a $C_{60}$. The small interspace formed between $C_{60}$ and junction provides a size changeable channel for the permselectivity of hydrogen while blocking $Ne$ and $Ar$. The sieving mechanism is due to the high compressibility of hydrogen.
