2025年1月15日 · Here, we report the structural transformation and temporal changes in the degradation mechanism of CuO x NPs under CO 2 RR conditions by using in situ small-angle X-ray scattering (SAXS), X-ray absorption near-edge structure (XANES) spectroscopy, and ex situ microscopic analysis.

2024年10月31日 · Here, inspired by drug capsules with extended-release structures, we construct a water-soluble carbonate shell on metal oxide catalysts. The shell acts as a protective coating, effectively slowing...

2024年11月13日 · The CuO/CeO 2 nanocomposites featuring a p–n heterojunction demonstrated improved light absorption efficiency and enhanced separation and transport of photogenerated charges compared to the individual CuO or CeO 2.

2021年2月4日 · Nature Communications - Copper oxides (CuO) can selectively catalyze the electrochemical reduction of CO2 to hydrocarbons and oxygenates. Here, the authors study the activity and...

2015年12月21日 · We show that the CO 2 molecule is activated on the CuO surfaces, with an adsorption energy of −93 kJ/mol on the (011) surface, showing exothermic adsorption, while (111) and (1 11) surfaces show comparatively weak adsorption.

2024年6月4日 · We investigate the interaction of CO 2 with metallic and oxidized Cu (110) surfaces using a combination of near-ambient pressure scanning tunneling microscopy (NAP-STM) and theoretical calculations.

2023年12月14日 · Copper oxide nanomaterials have been suggested to be efficient for highly selective multi-carbon (C 2+) production in CO 2 reduction reaction (CO 2 RR), due to the introduction of surface Cu + species from oxide catalysts. However, the Cu + species on the catalyst surface are prone to being reduced to Cu 0 under reductive conditions during CO 2 RR.

All samples exhibited reduction peaks corresponding to CuO and La 2 CuO 4 within the temperature range of 190–300 °C, indicating that the reduction temperature of the perovskite catalyst is within 300 °C [31]. Particularly, the reduction peak of LC showed symmetrical characteristics, implying a relatively uniform distribution of Cu species ...

2024年5月1日 · Value-added conversion of CO 2 using solar energy is a sustainable strategy to address the energy crisis and environmental issues simultaneously. In this work, Cu–CuO/NC catalysts were successfully prepared by a sol-gel method, and the effects of Cu doping ratio and heat treatment temperature on the catalyst properties were investigated.
