近日,中国科学技术大学国家同步辐射实验室姚涛教授团队与华中科技大学夏宝玉教授团队和新西兰奥克兰大学王子运博士合作,综合利用多种同步辐射原位技术,在质子交换膜(PEM)二氧化碳转换机制的研究中取得重要进展,相关研究成果以“Durable CO2 conversion in the proton-exchange membrane system”为题,于2024年1月31日发表于《Nat...
However, it remains challenging to develop this into a robust process because efficient conversion typically requires alkaline conditions in which CO2 precipitates as carbonate, and this limits carbon utilization and the stability of the system7,8,9,10,11,12. Strategies such as physical washing, ...
在此,来自中国科学技术大学的姚涛&新西兰奥克兰大学的王子运&华中科技大学的夏宝玉等研究者开发了一种质子交换膜系统,该系统在源自废铅酸电池的催化剂下将CO2还原为甲酸,其中晶格碳活化机制起作用。相关论文以题为“Durable CO2 conversion in the proton-exchange membrane system”于2024年01月31日发表在Nature上。 碳...
The mixture was stirred at room temperature for 6 h, and the resulting dark-brown, viscous solution was poured into methanol. The fibrous solid was washed with methanol and dried under a vacuum. The proton nuclear magnetic resonance (1H NMR) spectrum of p-TPBr is shown in Supplementary ...
Moreover, AWE is sensitive to CO2 because highly concentrated alkaline electrolytes cause the precipitation of liquid electrolytes [8], [9]. Currently, proton-exchange membrane water electrolysis (PEMWE) using solid polymer electrolytes has been embraced to solve the aforementioned issues related to ...
Lithium metal batteries using solid electrolytes are considered to be the next-generation lithium batteries due to their enhanced energy density and safety. However, interfacial instabilities between Li-metal and solid electrolytes limit their implementa
In the ZAB using the self-supported MnOx-S electrode, both significant discharge peak power density (74 mW/cm2 at 135 mA/cm2) as well as low voltage difference between charge and discharge processes (0.75 V) were observed. In addition, for charge-discharge cycling at 20 mA/cm2, the ...
Replacing platinum by a less precious metal such as palladium, is highly desirable for lowering the cost of fuel-cell electrocatalysts. However, the instability of palladium in the harsh environment of fuel-cell cathodes renders its commercial future ble

The development of highly active and cost-effective catalysts based on noble metal free oxygen electro-catalysis is critical to energy storage and conversion devices. Herein, we highlight a plasma-treated Bi0.1(Ba0.5Sr0.5)0.9Co0.8Fe0.2O3−δ perovskite (denoted as P-Bi0.1BSCF) as a prom...
