High-Resolution X-ray Absorption Spectroscopy of Soluble Methane Monooxygenase: Room Temperature and Cryogenic Insights into Active Site Electronic Structure Modulation

Abstract Room temperature HERFD XAS (High Energy Resolution Fluorescence Detected X-ray Absorption Spectroscopy) data collected on the stable Fe(III)Fe(III) (ox) and Fe(II)Fe(II) (red) states of the soluble methane monooxygenase hydroxylase (sMMOH) from Methylosinus trichosporium...

Adaptive Catalytic Synthesis of Aromatic and Aliphatic Amines via CO2-Induced Feedback Inhibition Using Standard Hydrogenation Catalysts

Abstract Adaptive catalytic systems, able to adjust or be adjusted reversibly in their performance, are finding increasing interest in science and technology. Yet, their development is currently associated with sophisticated catalyst designs integrating catalytic and stimuli-resp...

Access to Unsupported Iminobismuthane and Tetraazabismole Species Enabled by a Rigid and Bulky Organobismuthinidene

ABSTRACT Herein, we report the reactivity of a monocoordinate bismuthinidene ( 1 ) with various organic azides. The reaction of 1 with p ‐toluenesulfonyl azide resulted in the formation of an unprecedented, unsupported iminobismuthane ( 2 ), which features the shortest reported B...

Effects of Polyaromatic Film Interfaces on Cu Catalysts for Selective Electrochemical CO2 Reduction

Abstract Electrochemical CO2 reduction (CO2RR) offers a sustainable pathway to convert CO2 into energy-dense fuels and value-added chemicals, addressing both climate and energy storage challenges. This study investigates the effect of polyaromatic film (PAF) coatings on Cu-based...

Contrasting Roles of Rare-Earth and Ga Oxide Additives in Spinel-Derived Water-Tolerant Ni-Co/Al2O3 Catalysts for Ammonia Decomposition

Abstract In this study, Ni-Co-Al mixed oxides were synthesized via continuous-flow hydrothermal synthesis (CFHS) in supercritical water (T ≥ 445 °C, p = 24 MPa) and combined with different loadings of La-, Ce-, and Ga-based oxides. From these precursors, catalysts for the decompo...

Nickel(I) in an All-FerricNiFeS Cluster

Abstract Anaerobic carbon monoxide dehydrogenase (CODH) enzymes interconvert CO2 and CO under mild conditions and with near perfect selectivity. The CODH active site, termed the C-cluster, is a [NiFe3S4]-Feu cluster that can reside in several different oxidation states. Despite d...
