Additive-Free, Robust H2 Production from H2O and DMF by Dehydrogenation
Hits:125    Update:2017/6/14 8:26:33


Liquid organic hydrides, such as water, methanol and formic acid, can be catalytically converted into H2 gas, and thus are promising for overcoming the challenges associated with H2 storage and transport. However, the practical use of such carbon hydrides still faces many challenges: 1) safety issues; 2) the toxicity of some carbon hydrides; 3) the release of CO2 and even CO with H2 generation; 4) the use of expensive noble metals as catalysts. Therefore, to develop a green, safe, efficient and robust earth-abundant catalyst for H2 generation is a long term target.
Recently, Prof. Qu group in Frontier Institute of Science and Technology (Xi’an Jiaotong University) describe an alternative pathway for highly efficient and robust H2 production through a dehydrogenation reaction between water and N,N-dimethylformamide catalyzed by Cu/Cu2O catalysts formed in situ. The catalysts exhibit high and robust activity for H2 production. Importantly, the formation of H2 as the sole gas and the valuable by-product N,N-dimethylaminoformic acid make this process clean and valuable with 100% atom economy.
The research results are published at Angewandte Chemie International Edition (IF=11.709) titled with “Additive-Free, Robust H2 Production from H2O and DMF by Dehydrogenation Catalyzed by Cu/Cu2O Formed In Situ”.
Prof. Qu’s group focus on the design and applications of multiple scales materials in catalysis including high temperature catalysis, heterogeneous organic catalysis and electro-catalysis (OER and HER). Excellent students are warmly welcome to join us!
