A Biochar‐Based Composite Hydrogel Microenvironment for Enhanced Biocatalysis

open access: yesAdvanced Materials, EarlyView.
This work presents the synthesis of a polyacrylamide hydrogel wherein biomass‐derived biochar is co‐encapsulated with the enzyme horseradish peroxidase (HRP). The resulting composite hydrogel possesses balanced electron‐rich and electron‐deficient domains, creating an optimal microenvironment that concentrates both hydrogen peroxide and phenol ...

Defect‐Healed Au/rGO Coating for the Corrosion Protection of PEMFC Bipolar Plates

open access: yesAdvanced Materials Technologies, EarlyView.
 A defect‐healed gold/reduced graphene oxide (Au/rGO) coating is presented for stainless steel bipolar plates in polymer electrolyte membrane fuel cells. Gold nanoparticles nucleate at graphene oxide defects, blocking corrosive ion penetration and enhancing corrosion resistance, thereby ensuring durable fuel cell operation.
