英文摘要: Hydrous hydrazine is identified as a hydrogen reservoir owing to its high content of hydrogen (8.0 wt %). Its selective decomposition under mild conditions is the key for quick H-2 release. Modifying Ni nanoparticles with a small amount of CeO2 (8.0 mol %) resulted in a 3-fold increase of turnover frequency (TOF) and an enhancement of H-2 selectivity from 67% to above 99%. This improvement was due to the modification of Ni with CeO2 nearby through strong metal-support interaction (e.g., Ni-O-Ce structure). Furthermore, this promoting effect was extended to other oxides which can form strong metal-support interaction with Ni, such as ZrO2, MgO, and La2O3.
