Exploration of activity control strategies and mechanisms for efficient HCOOH dehydrogenation catalysts
甲酸具有氢含量高、毒性低、成本低、稳定性高、副产物简单等特点,已经作为有潜力的氢气储存材料,吸引了人们的广泛关注.本论文综述了惰性载体、还原性氧化物、金属有机框架材料、碳材料及分子筛作为载体分散Pd及Pd与其他金属形成的合金纳米粒子在甲酸脱氢反应中的活性.进一步总结了热(光或光热)催化甲酸脱氢反应机理.对于甲酸脱氢反应面临的挑战从提高活性金属利用率、采用理论计算深层次理解耦合效应、借助先进表征技术手段理解反应机理、实现碳循环角度进行了展望.
Formic acid(HCOOH)is taken as a promising H2 carrier,which has attracted wide concern as a result of high hydrogen content,low toxicity,high stability and simple byproducts.In this paper,we review the catalytic activity of Pd nanoparticles and Pd alloy metal nanoparticles loaded with inert carriers,reduced oxides,metal organic framework materials,carbon materials,as well as molecular sieves.Further,we summarize the reaction mechanism of the HCOOH dehydrogenation reaction driven by thermal energy,photo energy and photo-thermal energy.Finally,we provide the prospects to the challenges faced by HCOOH dehydrogenation reaction from the view of improving the utilization of active metals,using theoretical calculations to deeply understand coupling effects,utilizing advanced techniques to explore reaction mechanisms and realizing carbon cycling.
