B, N‐Co Doped Porous Carbon Nanotubes Supported Cu Single Atoms and B‐Doped Cu Nanoparticles for High‐Performance Electrocatalytic NO3RR and Zn‐Nitrate Batteries

Carbon Energy, EarlyView.
The ToC image shows a porous B, N‐doped carbon nanotube decorated with B‐doped Cu nanoparticles for nitrate‐to‐ammonia conversion. The unique structure enhances charge transport, promotes the adsorption and activation of key intermediates, alters the rate‐determining step, suppresses hydrogen evolution, and improves NH3 yield and Faradaic efficiency ...

Modelling of Hg Removal from Gaseous Streams and its Fixation in Hydroxyapatite-Based Adsorbents Modified with Copper Sulphide

Adsorption Science & Technology, 2015
In this work, a mathematical model of a fixed-bed process for elemental mercury removal from gaseous streams is proposed. Advective and diffusive processes were taken into account in the macroscopic mass balance along the bed, and diffusive process was ...

Synthesis of the Phospha‐Wittig Reagent Me3P = P(C2F5) and Generation of a Phospanyl‐Wittig Derivative Me3P = C(CF3)P(C2F5)F

Chemistry – A European Journal, EarlyView.
The first example of a simple alkylated phosphinidene‐adduct (“phospha‐Wittig”) is reported. The synthesis of Me3PPC2F5 was enabled through reaction of the cyclotetraphosphane (PC2F5)4 with PMe3. The phosphanyl‐functionalized Wittig reagent Me3PC(CF3)P(C2F5)F was prepared by treating the diphosphane P2(C2F5)4 with PMe3.

Silica‐Supported Mononuclear Methyl‐Platinum Complexes Stabilized by Trimethylphosphine—Synthesis, Structure, and Reactions Under Reducing Conditions

Chemistry – A European Journal, EarlyView.
The article describes the synthesis and molecular transformations of a silica‐supported bis(phosphine)methylplatinum(II) complex under reactive (H2, CO) and inert gas atmospheres. The focus lies on the stabilizing effect of the sterically non‐demanding trimethylphosphine ligand, which alters the reactivity of the surface sites, compared to other ...

Towards Halogen Bonding MOFs: Networking With a Polyiodinated and Perfluorinated Terphenyl Ligand and Divalent Zinc

Chemistry – A European Journal, EarlyView.
One ligand, three new architectures with different intermolecular interactions: a polyhalogenated terphenyl linker with carboxyl groups coordinates Zn2+ to form (i) a metal‐containing hydrogen‐bonded organic framework; (ii) a metal‐organic framework or (iii) one‐dimensional metal‐organic chains with intermolecular halogen bonding and hydrogen bonding ...
