Activity and stability origin of core-shell catalysts: Unignorable atomic diffusion behavior The exceptional oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) performances of core-shell catalysts are well-documented, yet their activity and durability origins have been interpreted only based on the static structures.

AbstractCO2 electroreduction is a potential pathway to achieve net-zero emissions in the chemical industry. Yet, CO2 loss, resulting from (bi)carbonate formation, renders the process energy-intensive. Acidic environments can address the issue but at the expense of compromised product Faradaic efficiencies (FEs), particularly for multi-carbon (C2+) products, as rapid diffusion and migration of protons (H+) favors competing H2 and CO production.

Mycotoxins are toxic metabolites produced by molds during their growth and reproduction, which enter the bodies of humans and animals via contaminated food, causing acute or chronic toxicity [1], [2]. Aflatoxin B1 (AFB1), the most toxic mycotoxin, has been classified as the group I potent carcinogen by the World Health Organization, which widely exists in various agricultural products and foods items [3], [4].

AbstractGiven the growing emphasis on energy efficiency, environmental sustainability, and agricultural demand, there’s a pressing need for decentralized and scalable ammonia production. Converting nitrate ions electrochemically, which are commonly found in industrial wastewater and polluted groundwater, into ammonia offers a viable approach for both wastewater treatment and ammonia production yet limited by low producibility and scalability.
