Unveiling Synergistic CuAuAg Nanoparticles on CuO for High‐Yield CO2 Electroreduction

open access: yesCarbon Energy, EarlyView.
Pulsed laser irradiation in liquid synthesis was employed to fabricate a trimetallic catalyst composed of CuAuAg nanoparticles uniformly decorated on CuO nanosheets (CuAuAg/CuO composite). This catalyst exhibits remarkable electrocatalytic performance for the reduction of CO2 to CO, achieving a high CO yield rate of 5.1 mmol h−1 cm−2 and a Faradaic ...

New Zeolitic Imidazolate Framework‐Derived N‐Doped Carbon LiCl Composites for Sorption Thermal Batteries Utilizing Solar Energy

open access: yesCarbon Energy, EarlyView.
New hierarchical ZIF‐derived nitrogen‐doped carbons (ZDCs) impregnated with LiCl are promising materials for sorption thermal batteries utilizing solar energy. This study examines the structural properties of ZDCs, the effect of LiCl loading, the enhancement of hydrothermal stability by nanoporous carbon, and the water adsorption properties of a series

Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

open access: yesChemistry – A European Journal, EarlyView.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...
