Nickel Hydroxide Catalyzed Bias‐free Photoelectrochemical NH3 Production via Nitrate Reduction

open access: yesAdvanced Materials, EarlyView.
A bias‐free photoelectrochemical nitrate reduction reaction with high efficiency and production rate is achieved using a crystalline silicon photocathode with nickel as the catalyst. Performing the PEC NO3RR under alkaline conditions can be self‐activated of the Ni surface by forming Ni(OH)2.

A Light‐Driven Closed‐Loop Chemical Recycling System for Polypinacols

open access: yesAdvanced Materials, EarlyView.
This study presents a novel strategy for the photochemical closed‐loop recycling of hydroxyl‐rich polymers. Simple bis‐aldehyde precursors are employed to synthesize polypinacols via UV light irradiation. Subsequent depolymerization is achieved under visible light using a cerium‐based photocatalyst, enabling monomer recovery through selective cleavage ...

Stimuli‐Responsive Low‐Frequency Terahertz Absorption ON‐OFF Switchability in Spin‐Crossover Material

open access: yesAdvanced Materials, EarlyView.
A switchable Fe(II)–Hg(II) coordination polymer exhibits reversible ON‐OFF terahertz (THz) absorption through temperature‐ and light‐induced spin‐crossover. The material shows strong, tunable THz responses linked to phonon modes around Fe(II) centers, supported by spectroscopic measurements and calculations.

Polystyrene Nanoplastic‐Mercury Complexes Detection by Electrolyte‐Gated Carbon Nanotube Field‐Effect Transistor‐Based Sensors

open access: yesAdvanced Materials Interfaces, EarlyView.
An electrolyte‐gated field effect transistor sensor is used to detect an environmentally relevant nanoplastic model. The sensor identifies the presence of polystyrene nanoplastics in water dispersions without significantly altering its performance in the presence of mercury on the nanoplastics’ surface, indicating that it may be utilized in ...
