摘要: Designing and developing materials with specific properties are nowadays important tasks. These could be achieved by choosing the adequate conditions, from a myriad of possibilities, being aware that slight changes in preparation method have major impact on final material. With work presented here, we showing kinetically controlled surface nano-structuring (NPs formation deposition over solid supports) scCO2 is versatile way for preparing active materials. Size, composition, morphology organization/architecture supported metal NPs can playing type metal, precursor, reaction media composition (stronger or weaker reducing media) different supports employed. Moreover, direct correlation between physical (size, morphology, organization) chemical (composition, chemistry) demonstrated systems catalytic behaviour, yield selectivity, exemplified N-alkylation amines alcohols.
