Transformative Masked Ortho‐Quinone Chemistry: From Direct Guaiacol Activation to Lignin‐Based Adhesives

Angewandte Chemie International Edition, EarlyView.
Renewable guaiacols are rapidly oxidized by phenyliodine(III)diacetate to masked ortho‐quinones, giving a new class of monomers that undergo selective Michael‐type polyaddition with multithiols to from thiol‐guaiacol connectivity‐bearing polymers. The activation applies to discrete monomers and directly to lignin, enabling two‐component adhesives that ...

Structural and Chemical Dynamics of Cu/NiO/Cu(100) Surfaces During CO2 Hydrogenation

Angewandte Chemie International Edition, EarlyView.
Dynamic segregation as a design principle for Cu–Ni catalysts. Operando LEEM/XPEEM tracks reduction, reshaping, and surface segregation processes taking place in Cu‐encapsulated NiO islands supported on Cu(100) during CO2 hydrogenation. ABSTRACT Understanding the dynamic restructuring of bimetallic catalysts under reaction conditions is key to ...

Catalytic Pyrolysis of Waste Polystyrene Over Fe–B Composite Catalyst for Enhanced Liquid Fuel Production

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Healthcare derived polystyrene waste represents a growing and under addressed fraction of plastic waste streams due to contamination risks and limited recyclability. This study aims to investigate the valorization of waste polystyrene foam through catalytic and noncatalytic pyrolysis pathways to evaluate product yield distribution and identify
