Mechanism of fast hydrogen generation from pure water using Al–SnCl2 and bi-doped Al–SnCl2 composites

The mechanism of fast hydrogen generation from pure water using selectively activated Al–SnCl2 composites was elucidated with the help of experimental data using combined XRD, SEM, EDX, DSC and calorimetric techniques. It is found that H2 is produced from two different but simultaneous routes specific to the Al–SnCl2 composite stoichiometry achieved after ball milling the precursor that readily yields, besides the excess of Al, Sn and AlCl3....
