Abstract

Hydrogen is recognized as a promising energy scours in the close future. Online hydrogen preparation from formic acid under mild reaction conditions causes extensive interests. Mo₂C and metal (Fe, Ni, Co, K) doped Mo₂C on granular activated carbon (GAC) were prepared and used as heterogeneous catalysts for H₂ generation from formic acid on a fixed bed reactor at 100–250°C. The formic acid conversions on doped Mo₂C-Me/GAC are clearly improved, especially at lower reaction temperatures. Co doping presents outstanding effect on H₂ selectivity and conversion rate compared to Ni and Fe. A 56.3% formic acid conversion was reached on Mo₂C-Co/GAC at 100°C, which triples that on Mo₂C/ GAC at the same temperature. At 150°C, a high formic acid conversion over 90% was reached on Mo₂C-Co/GAC. These long lifetime catalysts with no precious metal provide a low cost route to hydrogen production from formic acid.
