Design of Terpene‐Based Eco‐Friendly Solution Process for High‐Performance Organic Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
High‐performance, terpene‐processed organic solar cells (OSCs) by designing a new green co‐solvent system consisting of eucalyptol (Eu) and 2‐methyltetrahydrofuran (MeTHF) are developed. The OSCs processed from the optimal ratio of Eu and MeTHF achieve the highest power conversion efficiency (PCE) value of 17.3% reported to date for terpene‐processed ...

Phase‐Stable Palladium Hydride Derived from PdCoO2 for Sustainable Hydrogen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
The exceptionally active β‐PdHx is demonstrated for the hydrogen evolution reaction in acidic media. The fast activation kinetics from the PdCoO2 template are resolved by operando spectroscopy, and isotope‐labeled atom probe tomography quantifies the H content in β‐PdHx. The outstanding stability of the electrocatalyst is attributed to the retention of

Using In Situ TEM to Understand the Surfaces of Electrocatalysts at Reaction Conditions: Single‐Atoms to Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
This review summarizes recent advances in closed‐cell in situ TEM strategies for accurate determination of the activity and stability of single‐atom catalyst systems during operation. Operando conditions causing dynamic changes of SAC systems are highlighted and we explain why ensemble average‐based optical techniques may benefit from the technological
