Synthesis of Primary Amines via Reductive Amination of Aldehydes and Ketones Over a Ni‐Doped MFM‐300(Cr) Catalyst

Advanced Science, EarlyView.
Reductive amination of aldehydes and ketones to primary amines with high selectivity and yield can be achieved over Ni‐doped MFM‐300(Cr) in the presence of NH3 and H2. In situ inelastic neutron scattering, coupled with modeling, reveals that cooperativity between Ni active sites and MFM‐300(Cr) affords an optimal microenvironment for the selective ...

Suppressing the Electron–Phonon Coupling in 2D Perovskite Cs3Sb2I9 for Lead‐Free Indoor Photovoltaics

Advanced Science, EarlyView.
The study has developed an in situ anion‐exchange strategy to fabricate Pb‐free Sb‐based perovskite‐inspired materials (Sb‐PIMs) and solar cells, achieving a record indoor efficiency of 8.2% and a 3.4% power conversion efficiency under 1 sun illumination.

Synthesis of Functional Materials Using N‐heterocyclic Amines Beyond Melamine

Advanced Science, EarlyView.
Melamine has long enabled supramolecular assemblies, polymers, and carbon nitrides, yet related N‐heterocyclic amines remain underexplored. This review highlights advances with melamine analogues such as 6‐phenyl‐, 6‐methyl‐triazine diamines and 2,4,6‐triaminopyrimidine, focusing on how structural variation governs reactivity, condensation, and ...

Design Rule for Highly Stable Efficient High‐Entropy Metal Oxide Electrocatalysts: Complementary Roles of 3d Transition Metal Ions

Advanced Science, EarlyView.
Design rules for robust high‐performance metal oxide electrocatalysts are established by studying complementary roles of 3d transition metal ions. Based on the systematic investigation on the impact of metal substitution, several 3d metal ions are selected as optimized substituent ions.
