Temperature-responsive dissolution/recrystallization of Zn MOF enables the maximum efficiency and recyclability of catalysts

Abstract

A novel strategy through a temperature-responsive dissolution and recrystallization process has successfully achieved 100% atomic utilization and easy recyclability of heterogeneous metal organic framework dimethylammonium zinc formate (DMZnF) catalysts for highly efficient dehydrogenation of DMF–H₂O for hydrogen generation. DMZnF dissolves as a homogeneous catalyst at high reaction temperatures and then is recrystallized and recycled as a heterogeneous catalyst at low temperatures.
