Light-Driven CO Fixation into Epoxides Using an AlO/CoAlO Composite Photocatalyst.

Utilization of carbon dioxide (CO) as a C1 feedstock to synthesize value-added chemicals using a catalyst made from earth-abundant elements and under mild conditions is a sustainable approach toward carbon neutrality but difficult to achieve. Herein, the CoAlO/AlO composite catalyst is developed and used for the light-driven epoxide to value-added cyclic carbonate conversion using CO. CoAlO/AlO composite catalysts (% Co-AlO) are prepared by calcining cobalt-incorporated Al-oxy-hydroxide at 500 °C under an air atmosphere.

The antimicrobial properties of silver and silver complexes have been known in medicine since ancient times. However, limitations in stability and solubility have impaired medicinal chemistry and drug development research. With the advent of N-heterocyclic carbenes (NHC) as ligands, the development of synthesis methods for organometallic silver species of the type (NHC)AgX (where X = halide) has brought significant improvements, and the class of antimicrobial silver NHC complexes has emerged.

We study the influence of electrical biasing on the modification of the chemical composition and electrical performance of perovskite solar cells (PSCs) by coupling electrochemical impedance spectroscopy (EIS) and scanning transmission X-ray microscopy (STXM) techniques. EIS reveals the formation of charge accumulation at the interfaces and changes in the resistive and capacitive properties. STXM study on PSCs after applying a strong electric field for a long biasing time indicates the breakdown of methylammonium (MA) cation, promoting iodide ions to migrate and create defects at the interface.

With promises for high specific energy, high safety and low cost, the all-solid-state lithium-sulfur battery (ASSLSB) is ideal for next-generation energy storage. However, the poor rate performance and short cycle life caused by the sluggish solid-solid sulfur redox reaction (SSSRR) at the three-phase boundaries remain to be solved. Here we demonstrate a fast SSSRR enabled by lithium thioborophosphate iodide (LBPSI) glass-phase solid electrolytes (GSEs).

Ethylenediamine (EDA), as an important chemical raw material and fine chemical intermediate, has been widely applied in various industries. Real-time monitoring of EDA is highly desirable in daily life due to its potential threat to human health. Herein, we report a molecular probe named 4,4'-(9-carbazole-3,6-diyl)bis(1-(naphthalen-2-ylmethyl)pyridin-1-ium) iodide (p-N-DPC·I) with ratiometric luminescent and colorimetric dual-mode responses toward EDA, endowing a highly sensitive and selective detection method for its real-time monitoring.
