Metal loading determines the stabilization pathway for Co2+ in titanate nanowires: ion exchange vs. cluster formation

Abstract: Co nanoparticles were produced and characterized on protonated titanate nanowires. Co deposits were obtained after low-temperature decomposition of Co2(CO)8 on titanate nanostructures. The carbonylation was carried out by vapor-phase adsorption in a fluidized bed reactor and the decarbonylation processes were followed by FT-IR spectroscopy and microbalance combined with temperature programmed reaction mass spectrometry. The band gap of Co-decorated titanate nanostructures determined by UV-VIS diffuse reflectan… Show more

“…Az adszorbeált Co 2 (CO) 8 A bomlás során a CO ligandum reagált a titanát felületi oxigénjével 13 . A DRIFT és a hõmérséklet programozott deszorpciós (TPR) spektrumok megegyeztek a különbözõ mennyiségû kobalt-karbonil prekurzor molekula alkalmazásakor: 2 és 4 wt% kobalt-karbonil is ugyanazt az eredményt mutatta.…”
