Formic acid (FA) is the simplest carboxylic acid in terms of structure. As one of its main decomposition products, carbon monoxide (CO) can be used as a center for various chemical synthesis applications. The biggest challenge of formic acid decomposition is the purity of CO, separation and purification processes often result in additional energy and economic losses. In this work, we introduce a non-metallic two-dimensional (2D) layered material, hydrogen boride (HB). It can catalyze the dehydration of FA from 120 ℃, achieving a FA conversion rate of about 97% and CO production rate of about 15 mmol g-1 h-1 at 300 ℃, with 100% CO selectivity across all tested temperature. The apparent activation energy (Ea) is 67.9 ± 5 kJ/mol, which is lower than most reported results.
