H2 generation upon hydrolysis of ammonia-borane catalyzed by stabilized transition metal nanoparticles has been demonstrated, showing high catalytic activity and the RhNP-3/THPP exhibits the best performance.
Ammonia-borane (AB) is one of the most promising fuel forms for the hydrogen economy, but the reaction requires a good catalyst to accelerate this hydrolysis reaction under ambient conditions. Here, H-2 evolution upon hydrolysis of ammonia-borane catalyzed by tetra-(p-hydroxyphenyl) porphyrin (THPP) stabilized transition metal nanoparticles (RhNPs/THPP, RuNPs/THPP, PtNPs/THPP) has been reported for the first time. The as-synthesized nanocomposites (TMNPs/THPP) show high catalytic activity in the AB hydrolysis. Among these TMNPs/THPP, the RhNP-3/THPP exhibits the best catalytic activity with a TOF of 213.64 mol(H2) mol(cata)(-1) min(-1). In addition, tandem reaction for 1,1-diphenylethylene hydrogenation has also confirmed the H-2 evolution upon hydrolysis of ammonia-borane. [GRAPHICS] .
