Photocatalytic Lignin Depolymerization and Cross‐Coupling With Alcohols to Produce Unsymmetric Aromatic Diols

Angewandte Chemie, EarlyView.
A photocatalytic approach for efficient one‐pot direct lignin depolymerization and subsequent cross‐coupling with alcohols for the production of unsymmetrical aromatic diols has been demonstrated. ABSTRACT Conversion of lignin into chemical products typically involves two separate steps, such as depolymerization and subsequent upgrading of monomers ...

Bifurcation of *COOH Pathway Determines HCOOH Formation in CO2 Electroreduction on Bismuth

Angewandte Chemie, EarlyView.
Driven by the mechanistic debate of Bi‐catalyzed CO2‐to‐HCOOH conversion, ambiguity remains regarding true reaction pathways. To resolve this, we combined constant‐potential AIMD simulations with spectroscopic evidence to analyze the competitive pathways.

Facet‐Dependent Water Inhibition of Alkanol Dehydration on TiO2 via Distinct Water–Alkanol Complexes

Angewandte Chemie, EarlyView.
Water inhibits alkanol dehydration on TiO2 through facet‐dependent manners via distinct IPA‐water complexes. On TiO2(001), water forms a strongly hydrogen‐bonded isopropoxide–H2O complex that readily dominates the surface and substantially elevates the activation barrier, whereas on TiO2(101), water weakly hydrogen‐bonds to molecular IPA, resulting in ...

Palladium‐Doping‐Enabled Interface Synergy for Superb Ampere Level Ammonia Electrosynthesis From Nitrate

Angewandte Chemie, EarlyView.
Isolated Pd sites in a metallic Co matrix boost nitrate‐to‐ammonia conversion. Pd doping optimizes intermediate adsorption and reconstructs the interfacial microenvironment, promoting cation enrichment and a hydrogen‐down‐oriented water network. This dual modulation facilitates proton transfer and intermediate stabilization, enabling high ammonia ...

Graphdiyne as a Hole‐Transport Channel in Carbon Nitride Heterojunctions for Synergistic CO2 Reduction and γ‐Butyrolactone Synthesis

Angewandte Chemie, EarlyView.
A fully metal‐free heterojunction constructed from graphdiyne (GDY) and polymeric carbon nitride (PCN) enables efficient coupling of CO2 reduction and tetrahydrofuran oxidation. GDY serves as a hole‐transport channel, establishing a built‐in electric field that drives spatial charge separation. The optimized catalyst achieves near‐unity selectivity for
