Summary: In this study, a novel aqueous Zn-C2H2 battery is demonstrated as an efficient approach for removing acetylene impurities from crude ethylene. This battery not only converts energy-consuming acetylene removal into electricity generation, but also reduces acetylene to ethylene. It exhibits high open circuit potential and power density, and can effectively remove acetylene even under simulated conditions. Furthermore, this battery can be universally applied for alkynes purification and electricity generation.

Summary: The research team has efficiently converted nitrate, a common pollutant in wastewater and groundwater, into valuable ammonia products using a Ru-dispersed Cu nanowire catalyst through electrochemical methods. This sustainable approach not only treats wastewater but also generates ammonia, but current low catalytic activities pose challenges. However, the team has developed a high-performance catalyst that achieves over 99% nitrate conversion into ammonia and successfully obtains high purity NH4Cl solid and NH3 liquid products.

Summary: By regulating the metal-support interactions, ligand-free isolated Ru atoms were successfully anchored on the amorphous layer of a monolithic Ti support, resulting in the preparation of a Ru single atom electrode. This electrode exhibited exceptional electrochemical performance, with high chlorine evolution activity and selective reduction of nitrate to ammonia. Moreover, the size of the monolithic electrode can be scaled up, indicating its potential for industrial electrocatalytic applications.

Summary: In this study, copper selenide nanoflakes were synthesized on copper foam and exhibited bifunctional catalytic activity for hydrogen evolution reaction (HER) and hydrazine oxidation reaction (HzOR). The high copper deficiencies in the Cu2-xSe phase contributed to faster electron transfers and the Cu2Se berzelianite phase played a role in long-term electrocatalytic stability. The catalysts showed potential for electrocatalytic hydrazine-assisted overall water splitting.

Summary: The study reveals that the d-p orbital hybridization between single-atom metals and sulfur species can serve as a descriptor for understanding the catalytic activity of SACs in Li-S batteries. Transition metals with lower atomic numbers, such as titanium, have been found to effectively bind lithium polysulfides and catalyze their electrochemical reaction. Single-atom metal catalysts embedded in three-dimensional electrodes prepared through a nitrogen coordination approach show high catalytic activity and low catalyst loading for improved sulfur utilization in Li-S batteries.
