Efficient NiIr alloy catalyst for selective hydrogenation of benzonitrile, crotonaldehyde and benzylideneacetone

Catalysis Communications, 2023
SiO2-supported NiIr alloy acted as an effective heterogeneous catalyst for the hydrogenation of benzonitrile, crotonaldehyde and benzylideneacetone, showing much higher activity than monometallic Ni/SiO2 and Ir/SiO2 catalysts and superior selectivity to ...

Synthesis of Ni/NiAlOx Catalysts for Hydrogenation Saturation of Phenanthrene

Frontiers in Chemistry, 2021
The saturation of octahydrophenanthrene was the rate-determining step in the hydrogenation process from phenanthrene to perhydrophenanthrene, which was due to the steric hindrance and competitive adsorption of octahydrophenanthrene.

Quasiparticle bandgap engineering of graphene and graphone on hexagonal boron nitride substrate [PDF]

, 2011
Graphene holds great promise for post-silicon electronics, however, it faces two main challenges: opening up a bandgap and finding a suitable substrate material.

"Narrow" Graphene Nanoribbons Made Easier by Partial Hydrogenation

, 2009
It is a challenge to synthesize graphene nanoribbons (GNRs) with narrow widths and smooth edges in large scale. Our first principles study on the hydrogenation of GNRs shows that the hydrogenation starts from the edges of GNRs and proceeds gradually ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

C2H2 semi-hydrogenation on the PdxMy cluster/graphdiyne catalysts: Effects of cluster composition and size on the activity and selectivity

Green Energy & Environment, 2022
C2H2 semi-hydrogenation has been widely applied in industry to eliminate trace C2H2 from C2H4 feed. C2H2 semi-hydrogenation to C2H4 on a series of the newly designed catalysts, graphdiyne (GDY) as a new carbon allotrope supported different sizes of PdxMy
