We report the aq. phase catalytic hydrogenation pyruvic acid, acetone, nitrobenzene, Alanine and 6-bromo-1-hexene using three immobilized nanoparticles: Ru NPs, Pd NPs and Pd/Ru bimetallic NPs. Triruthenium dodecacarbonyl and palladium acetate were used as precursors for ruthenium nanoparticles Ru (NPs) and palladium nanoparticles Pd (NPs) resp. Pd/Ru bimetallic nanoparticles was stabilized using n-dodecyl sulfide, and synthesized by pyrolysis method. Ru NPs, Pd NPs and Pd/Ru bimetallic NPs were immobilized on silica (SiO2). The nanoparticles were characterized using Scanning Electron microscope (SEM), transmission electron microscope (TEM) and X-ray diffraction (XRD). All reactions were conducted at 328K and approx. 5 MPa of hydrogen gas pressure, with 0.10 g catalyst in 30 mL of substrate (20 mM pyruvic acid in water). Pd and Ru monometallic nanoparticles showed low to moderate catalytic activity. In spite of the low catalyst-SiO2 loading, about 99% of all target compds. were converted to the desired product when Pd/Ru bimetallic nanoparticles was used within 24 h.

Well-defined Group VIII transition metal catalytic nanoparticles were prepd. following a pyrolysis method. Novel binary hierarchical systems were fabricated by electrospinning the metal nanoparticles in the presence of textile material, followed by at. layer (ALD) or pulsed-laser deposition techniques (PLD), resp. Immobilization of catalytic nanoparticles onto surfaces that consist of textile materials in the form of binary hierarchical systems is an attractive approach for green technol. applications. The resulting materials were characterized using electron microscopy, and x-ray diffraction, and inductively coupled plasma mass spectrometry. The results indicated a 5% loading of the nanoparticles onto the textile supports. The selective redn. of cinnamaldehyde derivs. at C=C bonds or C=O bonds using the novel materials will be described.

The design and synthesis of well-defined metallic and bimetallic nanoparticles (NPs), their characterization, and the assessment of how their size and shape-dependent properties influence their applications are important areas of investigation for advancing green technologies that protect the environment. This chapter reviews recent advances in the design and synthesis of metallic, bimetallic and semiconductor nanoparticles and their emerging applications in the production of energy and chemicals from biorenewable materials. This contribution focuses on nanoparticle-mediated processes for biomass transformation that include hydrogenation, hydrogenolysis, decarboxylation, small molecule oxidation, conversion of cellulosic materials, hydrocarbon formation, and production of fuel cells. These processes all have significant potential for development of green technologies.
