Synthesis and characterization of TiO2 nanotube supported Rh-nanoparticle catalysts for regioselective hydroformylation of vinyl acetate

“…Nanoscale Rh particles have been holding people's interests 14 for their novel electronic, magnetic, optical and catalytic properties. [15][16][17][18][19][20] Their enhanced performances, especially for size-dependent catalytic properties, result from their size or shape and high surface-to-volume ratio. 21 However, pristine Rh nanoparticles are thermally unstable and tend to agglomerate in solution when heated.…”

A high-performance Pt–Co bimetallic catalyst with polyethyleneimine decorated graphene oxide as support for hydrolysis of ammonia borane

“…Noble metals 11,12 and non-noble metals [13][14][15] have long been studied for the catalytic hydrolysis of AB. However, noble metal catalysts usually suffer from resource and cost limitations whereas non-noble metal catalysts only have moderate activity and stability.…”

Rhodium(0) nanoparticles supported on hydroxyapatite nanospheres and further stabilized by dihydrogen phosphate ion: A highly active catalyst in hydrogen generation from the methanolysis of ammonia borane

“…In addition, reducing the particle size of support from the microcrystalline to the nanocrystalline regime (from > 1 mm to <100 nm) can enhance the activity due to a higher external surface area and a large number of exchange sites [39]. Using nanotitania as support, for example, has provided a high catalytic activity of TOF ¼ 260 min À1 for the rhodium(0) nanoparticles in the hydrolysis of ammonia borane [40]. Our two recent papers have shown that reducing the particle size of support increases the catalytic activity of ruthenium(0) nanoparticles in hydrogen generation from the hydrolysis of ammonia borane at 25.0 ± 0.5 C from TOF ¼ 137 min À1 for micron size HAP [41] to TOF ¼ 205 min À1 for nanometer size nanoHAP [42].…”
