Spinel MCo2O4 (M= Ni, Fe, Mn, Cu and Zn) demonstrates excellent physicochemical
properties due to the combined effects of M2+ and Co3+ cations. Their inimitable optical …

Non-enzymatic biosensors based on mixed transition metal oxides are deemed as the most
promising devices due to their high sensitivity, selectivity, wide concentration range, low …

Xylene is a toxic carcinogen, which may irritate eyes and respiratory tract, or damage the
central nervous system. However, the traditional semiconductor gas sensor can only detect …

CuO/WO 3 hierarchical hollow microspheres, assembled from irregular two dimensional
(2D) nanosheets, were prepared by ultrasonic-wet chemical etching and pyrolysis in this …

In this paper, a NO 2 gas sensor with outstanding sensing performance based on NiCo 2 O
4/WO 3 nanocomposite was synthesized by a hydrothermal method. A variety of testing …

It is of great significance to develop low-cost, eco-friendly backup power sources for driving
gas sensors. In this work, a gas sensor based on the PANI/NiCo2O4 composite was driven …

Laccase-catalyzed oxidative reactions are increasingly examined as a reliable approach to
environmental analysis and remediation, and it is urgent to widen metal category to …

Mesoporous metal oxides have proven to be one kind of promising sensitive materials for
semiconductor gas sensors that have shown great potential in detection of volatile organic …

Xylene is one of the representative indoor pollutants, even in ppb levels, that affect human
health directly. Due to the non-polar and less reactive nature of xylene, its room temperature …

BTX (benzene, toluene and xylene) gases, as the aromatic group of volatile organic
compounds (VOCs), are some of the most hazardous pollutants among VOCs. In order to …
