Catalysis offers cleaner and more efficient chemical reactions for environmental scientists.
More than 90% of industrial processes are performed with a catalyst involved, however
research it is still required to improve the catalyst materials. The purpose of this work is to
contribute with the development of catalysts synthesis with two different approaches. First,
the precise size control of non-noble metals nanoparticles. Second, a new one-pot synthesis
method based on a microemulsion system was developed to synthesize size-controlled
metal nanoparticles in oxide supports. The one-pot method represents a simple approach to
synthesize both support and immobilized nanometer-sized non-noble metal nanoparticles
in the same reaction system. Narrow size distribution nickel, cobalt, iron and cobalt-nickel
nanoparticles were obtained. High metal dispersions are attainable regardless the metal or
support used in the synthesis. Thus, the methodology is adaptable and robust. The sizecontrolled
supported metal nanoparticles offer the opportunity to study size effects and
metal-support interactions on different catalytic reactions with different sets of metals and
supports.
