“…Thermal analysis reveal that the decomposition of MIL-68(In) occurs in the temperature of 400–600°C. That’s why the calcination temperature selected was above 600°C ( Cui et al, 2018 ; Sun et al, 2021 ).…”

In this study, Ag@In2O3 modified nickel foam (NF) was reported for its role as a non-enzymatic glucose sensor. Ag@In2O3 was prepared by a simple two-step method; preparation of a metal-organic framework (MOF) MIL-68(In) by solvothermal method, entrapment of Ag + by adding AgNO3 then drying it for 2 h to complete the entrapment process and subsequent calcination at 650°C for 3 h. The Ag@In2O3 modified NF was employed as a non-enzymatic glucose sensor to determine glucose concentrations in an alkaline medium. Two linear ranges were obtained from Ag@In2O3 modified electrode, i.e., 10 μM to 0.8 mM and 0.8–2.16 mM with a sensitivity of 3.31 mA mM−1 cm−2 and 1.51 mA mM−1 cm−2 respectively, with a detection limit of 0.49 µM. Ag@In2O3 modified NF exhibited high selectivity for glucose, among other interfering agents.

“…Obviously, RH of the background environment has an inhibitory effect on the response of both In 2 O 3 and In 2 O 3 /NiO-20C. Humidity interference has been a significant problem faced by In 2 O 3 materials. − The adsorption of water molecules reduced the number of adsorbed oxygen species and the active sites on the surface of the sensing layer, so the adsorption of NO 2 by the film was disturbed, which led to a decrease in the response.…”

To achieve high sensitivity under low-temperature operation is currently a challenge for metal oxide semiconductor gas sensors. In this work, a unique NiO-functionalized macroporous In 2 O 3 thin film is designed by atomic layer deposition (ALD), which demonstrates great potential in electronic sensors for detecting NO 2 at low temperature. This strategy allows for efficient engineering of the oxygen vacancy concentration and the formation of p−n heterojunctions in the hybrid In 2 O 3 /NiO thin films, which has been found to greatly impact the surface chemical and electrical properties of the sensing films. The sensor based on the optimized In 2 O 3 /NiO films exhibits a very high response of 532.2 to 10 ppm NO 2 , which is 26 times higher than that of the In 2 O 3 , at a relatively low operating temperature of 145 °C. In addition, an ultralow detection limit of ca. 6.9 ppb has been obtained, which surpasses most reports based on metal oxide sensors. Mechanistic investigations disclose that the improved sensor properties are resultant from the paramount surface active sites and high carrier concentration enabled by the oxygen vacancies, while excessive NiO ALD leads to a decreased sensor response due to the formed p−n heterojunctions.
