Nanoporous Gold as a Highly Selective and Active Carbon Dioxide Reduction Catalyst

Nanoporous gold catalyst for highly selective semihydrogenation of alkynes: remarkable effect of amine additives.

We report for the first time the highly selective semihydrogenation of alkynes using the unsupported nanoporous gold (AuNPore) as a catalyst and organosilanes with water as a hydrogen source. Under the optimized reaction conditions, the present semihydrogenation of various terminal- and internal-alkynes affords the corresponding alkenes in high chemical yields and excellent Z-selectivity withou...

Nanoporous gold as an active low temperature catalyst toward CO oxidation in hydrogen-rich stream

Preferential CO oxidation (PROX) was investigated by using dealloyed nanoporous gold (NPG) catalyst under ambient conditions. Systematic investigations were carried out to characterize its catalytic performance by varying reaction parameters such as temperature and co-existence of CO2 and H2O, which revealed that NPG was a highly active and selective catalyst for PROX, especially at low tempera...

Nanoporous carbon derived from a functionalized metal-organic framework as a highly efficient oxygen reduction electrocatalyst.

High levels of iron-nitrogen doped porous carbon materials are obtained from MOF-253 using a step-by-step post-synthetic modification strategy. MOF-253 possessing open 2,2'-bipyridine nitrogen sites not only serves as a precursor but also provides chelate bonding sites for Fe2+. Followed by further impregnation of 1,10-phenanthroline, high surface area porous carbon materials are obtained. For ...

Nanoporous nickel spheres as highly active catalyst for hydrogen generation from ammonia borane.

CoSi particles on silica support as a highly active and selective catalyst for naphthalene hydrogenation.

CoSi particles on a silica support, synthesized by metal organic chemical vapor deposition (MOCVD) of Co(SiCl(3))(CO)(4) as a precursor at atmospheric pressure and moderate temperature in a fluidized bed reactor, show high catalytic activity and selectivity in naphthalene hydrogenation.
