Hydrogen (H2) has drawn extensive attention due to its superior gravimetric capacity density and eco-friendly nature. Nowadays, hydrogen is mainly produced by the steam reforming of natural gas, a process that leads to massive emissions of greenhouse gases. Very recently, H2 evolution upon hydrolysis of diboranes (e.g., B2(OH)4 and B2pin2) is promising because both H atoms of the released H2 are obtained from water. This is different from the hydrolysis of sodium borohydride, dimethylaminoborane, ammonia borane, and tetramethyldisiloxane, where an H2 is generated with only one H atom from H2O and the other one from hydrogen storage materials. Importantly, diborane hydrolysis in D2O could provide an easy and simple method for D2 evolution. In this minireview, an overview of H2 evolution upon diborane hydrolysis with an extraordinary emphasis on the recent developments in mechanism study and applications is presented. The future research emphasis and perspectives of H2 evolution upon diborane hydrolysis have been suggested for commercialization as well.
