    Hydrogenation of Cinnamaldehyde Using Carbon Dots Reduced Palladium Nanoparticles

    Carbon dots (CDs) with a size range of 0.2 to 2 nm were prepared using a hydrothermal treatment of sucrose and oleic acid. The as-synthesized CDs were used to reduce H2PdCl4 to metallic Pd nanoparticles with dPd ...

    Polystyrene-b-poly(acrylic acid) nanospheres for the synthesis of size-controlled cobalt nanoparticles encapsulated inside hollow carbon spheres

    Metal particle agglomeration is known to be one of the factors responsible for the reduction in catalytic activity (even selectivity) when metal particles are supported on carbon. In this study, an approach us...
