Thin sol–gel SiO2–SnOx–AgOy films for low temperature ammonia gas sensor

Remarkable Improvement in Water Oxidation Catalysis by Moderate Heat Treatment of a Crystalline Silver‐Based Thin Film Developed In‐Situ From Silver‐ions in Acetate Solution

“…It is more abundant and cheaper compared to other nobel metals (e. g. Ru, Ir, etc.). Metal oxides involving Ag–O group are versatile materials and have been intensively pursued for promising application in oxidation catalysis,, sensors, fuel cells, all optical switching devices and optical data storage systems . Since both copper and silver are in the same group of periodic table, it is expected that like copper oxides (Cu 2 O and CuO), silver oxides (Ag 2 O and AgO) based materials also could be active as electrocatalysts for water oxidation.…”

Enhanced visible light-mediated photocatalysis, antibacterial functions and fabrication of a 3-chlorophenol sensor based on ternary Ag2O·SrO·CaO

“…6 It is well-known that silver ions and silver-based compounds have strong biocidal effects on many species of bacteria including E. coli 7 because they are highly toxic to microorganisms. 8 Ag 2 O nanoparticles have been widely used in the eld of oxidation catalysis, 9,10 fuel cells, 11 sensors, 12 photovoltaic cells, 13 all-optical switching devices, and optical data storage systems 14 and as diagnostic biological probes. 15 CaO is an alkaline earth metal oxide and has many applications as a catalyst, 16 toxic-waste remediation agent, doped material to modify electrical and optical properties, 17 refractory additive, 18,19 and crucial component in CO 2 capture [20][21][22] as well as in ue gas desulfurization and pollutant emission control.…”

Semiconducting Metal Oxide Based Sensors for Selective Gas Pollutant Detection

“…Further, an AFM study showed that the only films which were porous had a minimum Sn to Ag ratio of 0.5 and were annealed at 600 °C for eight hours, thus showing the best sensing characteristics. The films also showed good sensitivity to ammonia gas even at low temperatures (>50 °C) [190]. …”
