Exploring chromium oxynitrides as efficient catalysts for the water-gas shift reaction

Year: 2025

Type: article

Abstract: Transition metal nitrides and oxynitrides exhibit catalytic properties that make them promising candidates as alternatives to noble metals. A series of high-surface-area chromium oxynitrides, CrO x N 1-x (0.10 < x < 0.25), was synthesized from a cheap hydroxide precursor and investigated as unconventional heterogeneous catalysts for the Water-Gas Shift (WGS) reaction. Currently, this reaction is predominantly catalyzed by platinum. Replacing platinum with chromium oxynitrides could provide a more cost-effective and environmentally friendly solution. A series of high surface area chromium oxynitrides CrO x N 1-x (0.10 < x < 0.25) was synthesized from a hydroxide precursor and evaluated as a potential alternative to noble metal-based heterogeneous catalysts for the water-gas shift (WGS) reaction.
