      Graphene is a new 2D nanomaterial with outstanding material, physical, chemical, and electrochemical properties. In this review, we first discuss the methods of preparing graphene sheets and their chemistry. The fundamental reasons governing the electrochemistry of graphene are then described. Graphene is an excellent electrode material with the advantages of conductivity and electrochemistry of sp2 carbon but without the disadvantages related to carbon nanotubes, such as residual metallic impurities. We highlight important applications of graphene and graphene nanoplatelets for sensing, biosensing, and energy storage.

      We have studied the rational design of heterogeneous catalysis capable of high activity and selectivity. Platinum nanoparticles are synthesized in mesoporous silica, and the supported nanoparticles show the unique high activity and selectivity in preferential oxidation of CO in hydrogen for fuels cells. This promotional effect is due to the concerted effect of metal nanoparticles and supports. Supported metal catalysts have also been applied to biomass conversion. We found the degradation of cellulose by supported metal catalysts, in which bifunctional catalysis of acid and metal plays the key role for the hydrolysis and reduction of cellulose.

    3. Organophosphine syntheses via activation of the phosphorus-silicon bond of silylphosphines (pages 236–245)

      Recent advances in the syntheses of organophosphines via activation of the phosphorus-silicon bond of silylphosphines are described. Three types of the activation methods, nucleophile-induced activations, reactions with Lewis acid-activated electrophiles, and transition metal-catalyzed reactions, are summarized. Selective formations of P-C bond were achieved through these activations to produce a variety of functional organophosphines including optically active ones.
