Highly sensitive H2S sensors based on metal-organic framework driven γ-Fe2O3 on reduced graphene oxide composites at room temperature

A highly stable and sensitive ethanol sensor based on Ru-decorated 1D WO3 nanowires

“…Moisture negatively affects gas sensors, 18 so the effect of increasing humidity was investigated in this work. Fig.…”

“…1-3 Thus, they play a signicant role in gas sensing applications to detect toxic, inammable and explosive gases, 4-6 and are more favored by scientic researchers compared to sensors based on metamaterials [7][8][9][10] or nanophotonics. [11][12][13] MOS-based sensors have been reported over the past several decades, including sensors based on CuO, 14 SnO 2 , 15 In 2 O 3 , 16 Co 3 O 4 , 17 Fe 2 O 3 , 18 ZnO, 19 and NiO, 20 for applications such as monitoring air quality and ensuring industrial safety. The discharge and leakage of volatile organic compounds (VOCs) into the environment are inevitable because of the limitations of current production technology.…”

Ru-functionalized Ni-doped dual phases of α/γ-Fe2O3 nanosheets for an optimized acetone detection

“…It was found that at 3% Gd-doped γ-Fe 2 O 3 showed the response of 31.2 to 20 ppm acetone, which is 30 times more than that of γ-Fe 2 O 3 [16]. In addition, the γ-Fe 2 O 3 -based composites such as γ-Fe 2 O 3 / rGO [17] and ZnO/γ-Fe 2 O 3 [18] have been tested for H 2 S detection at room temperature. In general, the α-Fe 2 O 3 and γ-Fe 2 O 3 have been studied individually because of their different crystalline structures and intrinsic properties.…”

Insight into the Novel Z-Scheme Zif67/Wo3 Heterostructure for Improved Photocatalytic Degradation of Methylene Blue Under Visible Light

“…Owing to enormous prominent characteristics such as large surface area, excellent porous structure, stability and various types, they have attracted great interest in various applications such as energy storage, catalysis, separation, drug delivery gas storage, and so on. [11,12] In recent years, in light of their signi cant optical properties, MOFs have been extensively used in solar energy-driven technologies such as photocatalytic removal for contaminants, hydrogen energy production, CO 2 reduction, etc. [13] In this process, the used MOFs not only ameliorate the photocatalytic performance of the main catalyst, but also participate in the photocatalysis process [14].…”
