Abstract null null Herein, the spinel CdGa2O4 and off-stoichiometric spinel CdGa2O4 (CdO-CdGa2O4) with 3D inverse opal spherical structure have been synthesized by the combination of ultrasonic spray pyrolysis technology and self-assembled hard-template method. The CdGa2O4, with band gap of 4.14 eV and baseline resistance of Mohm-level, exhibited excellent selectivity and high response to 1ppm formaldehyde. On the other hand, the CdO-CdGa2O4 composites (Cd:Ga atom ratio = 1.2:2), with band gap o...

Abstract null null In this work, the RuCu bimetal was used in gas-sensitive material for the first time. We successfully synthesized small-sized RuCu bimetallic nanoparticles using a simple co-reduction method to modify SnO2 nanoparticle clusters. The structure morphologies of the synthetic materials were characterized and its gas sensing properties were tested in detail. Among them, the sensor based on 0.3 wt% RuCu modified SnO2 materials showed excellent sensing performance of n-pentanol. The ...

Abstract null null Bimetallic nanocrystals (NCs) have received a lot of attention due to its excellent catalytic performance. Here, PtRu NCs were successfully synthesized by ethylene glycol and used to modify flower-like WO3 which was prepared via a simple hydrothermal method. The morphology and structure of the as-synthesized materials were characterized, and the performance of the gas sensor based on PtRu NCs decorated WO3 was carefully studied. The gas sensing investigation showed that there ...

Abstract null null Although the construction of heterojunctions between two different oxides is an attractive strategy to improve the sensing performance of metal oxide semiconductor (MOS) based gas sensors, there are few research reports focus on constructing p-p heterojunctions. Here we presented the sensitive material of p-p heterojunctions CoWO4-Co3O4 nanocomposites derived from off-stoichiometric cobalt tungstate which are prepared through facile hydrothermal method. Owing to the presence o...

Abstract null null In this research, a semiconductor metal oxide (SMO)-based gas sensor was designed for the ultrasensitive and tunably selective detection of formaldehyde and acetone. Cobalt-doped 3D inverse opal SnO2 multilayer films (3D IO Co-SnO2 MFs) used as sensing materials were prepared with the ultrasonic nebulizing deposition (UND) method combined with a self-assembly template. The 3D IO Co-SnO2 (Co/Sn = 1:24 atom%) MF-based sensor exhibited a much higher response and lower limit of de...

Abstract null null Sensitive and selective determination of H2S has been widely reported. However, its gas sensing performance is vulnerable to some special environments such as high humidity. Especially, the sluggish response/recovery time and the unfavorable long-term stability are the main obstacles for H2S gas sensing. Herein, carbon modification on coral-like WO3 with bimodal pore distribution (mesopores and macropores) has been fabricated by one-step solvothermal method. Experimental resul...

Abstract null null Acetylcholinesterase (AChE), as an important neurotransmitter, is widely present in the peripheral and central nervous systems. The aberrant expression of AChE could cause diverse neurodegenerative diseases. Herein, we developed a facile and interference-free fluorimetric biosensing platform for highly sensitive AChE activity determination based on a NaErF4: 0.5 % Ho3+@NaYF4 nano-probe. This nano-probe exhibits a unique property of emitting bright monochromic red (650 nm) upco...

Abstract null null High-performance YSZ-based mixed potential NH3 sensor has been developed and utilized with the prospect of excellent applications in in-vehicle SCR (Selective Catalytic Reduction) systems. In order to further lower the detection limit and improve the sensitivity to NH3, we prepared Ag decorated FeVO4 as sensing electrode material through the NaBH4 reduction method in this work. Electrochemical methods such as cyclic voltammetry (CV), linear sweep voltammetry (LSV) and I-t curv...
