Bio‐Inspired Carbon Spheres Enable Active Sites Multiscale‐Anchoring and Pre‐Reduction

open access: yesCarbon Energy, EarlyView.
Combining the wet‐spinning technique with a “bionic design” concept, a bio‐inspired carbon sphere support with internal finger‐shaped pores and external craquelure structures is designed and constructed, and the corresponding carbon sphere reactor is fabricated through the multiscale anchoring and the pre‐reduced promoting, and verified for application

Sustainable Germanium Recovery From Germanium Dioxide via Halogen‐Free Chemical Vapor Transport

open access: yesChemistry – A European Journal, EarlyView.
Recovery of the critical element Ge from GeO2 and SiO2/GeO2 mixtures was investigated based on an endothermic chemical vapor transport via GeO, formed with natural gas or a hydrogen(10%)‑argon(90%) mixture and water vapor. (This picture was partly created with AI, engine: Adobe Firefly).

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

open access: yesChemistry – 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 ...

Ru Nanoparticle Supported by Mesoporous SiOx and Pillared Montmorillonite: Suppressing Catalyst Inhibition in Carbon Dioxide Hydrogenation

open access: yesChemistry – A European Journal, EarlyView.
Ru nanoparticles confined within mesoporous SiOx‐pillared montmorillonite exhibit exceptional performance for CO2 methanation. The catalyst maintains a high reaction rate even at elevated CO2 conversion while preserving high Ru mass–specific activity, overcoming typical inhibition by H2O and CO observed in conventional supported Ru catalysts.

Anion‐Selective Channels Formed by Synthetic 13‐Mer Chimeric α ‐Peptide‐Oligourea Foldamers

open access: yesChemistry – A European Journal, EarlyView.
Synthetic 13‐mer α‐peptide‐oligourea chimeric foldamers self‐assemble into supramolecular ion channels, demonstrating high ion transport activity with distinct anion selectivity in lipid membranes. This study supports the design of bioinspired functional foldamer‐based channels for synthetic ion transport applications.

Embedding a Dinuclear Ru─Pt Photocatalyst Into Polyampholytic Graft Copolymer Matrix Enables Prolonged Hydrogen Evolution While Allowing Catalyst Repair

open access: yesChemistry – A European Journal, EarlyView.
A unimolecular polyampholytic graft copolymer matrix provides a protective confinement for an electrostatically embedded tetrapyridophenazine‐bridged heterodinuclear Ru‐Pt hydrogen evolving photocatalyst. The matrix slows the degradation kinetics of the catalyst and at the same time does not hinder its repair by ammonium persulfate.
