Sunlight‐Driven Green Synthesis of Platinum Nanoparticles From Double‐Vacancy Halide Perovskite Precursors for Methanol Reforming

Chemistry – A European Journal, EarlyView.
ABSTRACT The development of synthetic procedures for preparing metal nanoparticles with controlled size using sunlight opens new avenues toward more sustainable methods with lower energy consumption. Herein, we propose the use of double‐vacancy halide perovskites as precursors for engineering highly crystalline and small platinum nanoparticles (< 3 nm)

Highly Efficient Sky‐Blue Perovskite Quantum Dot Light‐Emitting Diodes via Ligand‐Assisted Trap‐State Passivation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Highly efficient sky‐blue LED with EQE of 13.6% is realized through short‐chain ligand tridecylamine treaded perovskite quantum dots, due to the suppressed non‐radiative recombination from the trap state. These results indicate that the ligand with strong affinity can facilitate the surface defects passivation, resulting in enhanced optical properties,

Strong Nonradiative Recombination Induced by Pronounced Lone‐Pair Electron Expression Following Deprotonation in Aziridinium Lead Iodide Perovskites

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The transition from linear to cyclic organic cations promotes deprotonation and activates VH(N) defects with pronounced lone‐pair electron activity, thereby inducing severe local distortions and highly efficient nonradiative recombination centers. This work unveils a direct structure–defect–performance correlation and proposes design strategies for the

Bottlenecks‐Breaking in Zinc‐Iodine Batteries Toward Practical Implementation: A Review and Perspective

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Aqueous zinc–iodine batteries (Zn–I2Bs) offer promise for grid storage due to safety and cost advantages yet face critical bottlenecks: severe self‐discharge (polyiodide shuttling and HER), limited energy density, sluggish kinetics, and zinc anode instability.

Modulating Perovskite Crystallization via Multisite Bonding for Enhanced Solar Cell Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study proposes an innovative multisite bonding strategy to regulate crystallization. By employing bidentate ligands N,N‐diethyl‐1,2‐ethanediamine dihydrochloride (DED) that coordinate with uncoordinated Pb2+ and I− vacancies, while simultaneously forming hydrogen bonds with FA+ ions, this synergistic interaction prolongs the perovskite ...
