Özet

Here, carbon quantum dot (CQD) supported Ru nanoparticles from the caffeine in methanol or water by the hydrothermal method were synthesized for the first time to produce hydrogen (H₂) by hydrolysis of ammonia borane(NH₃BH₃) and their catalytic activities were investigated. The chemical compositions and morphology structures of this caffeine carbon dot-supported Ru catalysts were carefully characterized by UV, PL, TEM, FTIR, and ICP/OES analyses. Well-dispersed Ru nanoclusters with ∼1.81 nm particle size on CQD by the hydrothermal method in methanol medium showed very good catalytic performance. The turnover frequency (TOF) obtained for H₂ production from the catalytic hydrolysis of 5% NH₃BH₃ with CQD supported Ru catalyst obtained by the hydrothermal method in methanol and water was found to be 361 and 1895 mol H₂ min⁻¹ mol⁻¹, respectively. The activation energies (Ea) for NH₃BH₃ hydrolysis with the same catalysts were measured as 33.32 and 27.80 kJmol^-1, respectively.
