Tailoring of nanocrystals Bi2WO6 glass ceramics decorated with Sm3+ and Eu3+ ions for improving photocatalytic activity

Cobalt–Nitrogen Bonding for Triggering the Low-Power Dual Detection of NO2 and NH3 by Mixed-Valence Co2+ and Co3+

“…Nanostructuring, such as mixing, decoration, doping, and/or functionalization, has demonstrated the capability of enhancing surface-to-volume ratio, porosity, surface energies, geometric, electronic, and chemical effects that are critically significant not only for gas sensing but also biosensing, energy, and environmental applications, such as batteries, solar cells, photocatalysis, capacitors, catalysis, and OER . A plethora of literature on the valence of surface ions demonstrates different mechanisms for different applications . For example, Cu-doping in NiO gradually substitutes Ni 2+ ions, forming mixed-valence Cu + and Cu 2+ sites .…”

“…43 A plethora of literature on the valence of surface ions demonstrates different mechanisms for different applications. 44 For example, Cu-doping in NiO gradually substitutes Ni 2+ ions, forming mixed-valence Cu + and Cu 2+ sites. 45 This increases the carrier concentration and mobility, enabling effective charge transfer and extraction.…”
