Minuscule Amounts of Pt Single Atoms Selectively Loaded on Minor (101) Facet of Anatase Crystallites Enables Outstanding Utilization Efficiency for Photocatalytic H2 Production

open access: yesAdvanced Functional Materials, EarlyView.
Ar–H2 annealing triggers redistribution of pre‐deposited Pt single atoms (SAs) on faceted anatase nanosheets, with selective SAs accumulation on the minor (101) facetsthus the co‐catalytic SA‐sites are positioned only where they are needed, i.e. at the electron exit facets.

The Role of Fluorine‐Functionalized Organic Spacers for Defect Passivation and Low‐Dimensional Phase Formation in 3D MAPI Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
Fluorine‐functionalized organic spacers (2F, 3F, 5F) are investigated to identify as optimal passivation agents for 3D MAPI perovskite solar cells (PSCs). The study highlights how altering fluorine positioning affects defect passivation, low‐dimensional phase (LDP) formation, and stability, emphasizing its role in molecular interactions and offering ...

Over 18% Efficiency from Halogen‐Free Solvent‐Processed Polymer Solar Cells Enabled by Asymmetric Small Molecule Acceptors with Fluoro‐Thienyl Extended Terminal

open access: yesAdvanced Functional Materials, EarlyView.
An asymmetric non‐fullerene acceptor BTP‐FT is developed by extending the end group of Y6‐BO with thiophene. The conformation of the molecule is determined by the noncovalent F···S interaction as demonstrated by 2D NMR and simulations. An efficiency of 18.39% is achieved in the resulting ternary solar cells processed from toluene.

Photoswitchable Conductive Metal–Organic Frameworks

open access: yesAdvanced Functional Materials, EarlyView.
A conductive material where the conductivity can be modulated remotely by irradiation with light is presented. It is based on films of conductive metal–organic framework type Cu3(HHTP)2 with embedded photochromic molecules such as azobenzene, diarylethene, spiropyran, and hexaarylbiimidazole in the pores.

Oxygen Doping Enables Tailored Built‐In Electric Fields in FeOCl/g‐C3N4 Heterojunctions for Enhanced Peroxymonosulfate Activation

open access: yesAdvanced Functional Materials, EarlyView.
Oxygen‐doping modulated g‐C3N4 support enables a strong built‐in electric field (BIEF) in FeOCl‐OCN.This enhanced BIEF induces the rearrangement of Fe(II)/Fe(III) in FeOCl, which subtly improves intermediates adsorption and also reduces the energy barrier of *O production, thereby achieving efficient PMS activation with 1O2 and Fe(IV)= O as the primary
