Filtration of the preferred catalyst for reverse water-gas shift among Rh_<i>n</i>⁻(<i>n</i>= 3–11) clusters by mass spectrometry under variable temperatures

Abstract

clusters to drive the catalysis at a mild starting temperature (∼440 K). This finding represents the first example that a specifically sized cluster catalyst that works under an optimum condition can be accurately filtered by using state-of-the-art mass spectrometric experiments and rationalized by quantum-chemical calculations.
