Dilute Pd-in-Au alloy catalysts are promising materials for selective hydrogenation catalysis. Extensive surface science studies have contributed mechanistic insight on the energetic aspect of hydrogen dissociation, migration, and recombination dilute systems. Yet, translating these fundamental concepts to kinetics free energy dissociation nanoparticle operating at ambient pressures temperature...

Production of hydrogen (H2) from H2 storage materials is very attractive as a source sustainable energy. We report that [email protected] alloys are efficient nanocatalysts for evolution upon ammonia borane hydrolysis under visible-light illumination with turnover frequency 3.4 times higher than the monometallic Ni catalyst in dark. This improvement attributed to dramatic volcano-type positive ...

The switch from a carbon-based to hydrogen-based economy requires environmentally friendly methods for hydrogen production. CO 2 -reforming of methane promises be greener alternative steam-methane reforming, which accounts the majority production today. For this dry process become industrially competitive, challenges such as catalyst deactivation and degradation through coke formation must bett...

• PdCu single atom alloys (SAA) selectively catalyse furfural hydrogenation. Successful deposition of Pd atoms on Cu nanoparticles via galvanic replacement. SAAs are catalytically superior to monometallic and catalysts. host enhance hydrogen dissociative adsorption. Single-atom catalysts serve as a skilful control precious metals heterogenous where all active sites accessible for catalytic reac...

Lowering or eliminating the noble-metal content in oxygen reduction fuel cell catalysts could propel large-scale introduction of commercial systems. Several free are already under investigation with metal-nitrogen-carbon (Me-N-C) system being one most promising. In this study, a systematic approach to investigate influence metal ratios bimetallic Me-N-C cells reaction (ORR) has been taken. Diff...

Lignin is an attractive renewable source of aromatics with a low effective hydrogen to carbon ratio (H/Ceff). The catalytic hydrodeoxygenation (HDO) lignin-derived model compounds key strategy for lignin upgrading. In this work, the HDO guaiacol, typical compound, was carried out over metal–organic framework (MOF)-derived Ni-based catalysts. A monometallic Ni-MOF catalyst and different ratios b...

Carbon materials have attracted increasing attention as supports for metal catalysts. Iron-containing carbon nanotubes often promoted with copper found application in Fischer-Tropsch synthesis, which provides an alternative way conversion of renewable feedstocks to chemicals and fuels. In nanotubes, the active phase can be nanoconfined inside channels or localized on outer surface. most previou...

Series of Copper Ruthenium (Cu-Ru) bimetallic catalysts supported on γ-Al2O3 with different metal loading are prepared and investigated for catalytic wet air oxidation of ammonia to nitrogen. The ammonia decomposition activity was studied at three different temperatures i.e. 150oC, 200oC, and 230 oC and it is found that catalytic activity increases with the increase in temperature along with th...

Unlike the conversion of monosaccharides to corresponding polyols, production maltitol by hydrogenation maltose has been seldom investigated in literature, despite its industrial importance. Monometallic Ni catalysts are known for their lack stability, and objective present paper is determine through a kinetic study, what extent Ni-Fe/SiO2 bimetallic catalyst would outperform Ni/SiO2 aqueous ph...
