Synthesis of hierarchical SnO2 nanoflowers and their high gas-sensing properties

Synthesis and enhanced photocatalytic property of feather-like Cd-doped CuO nanostructures by hydrothermal method

“…Many previous references have reported the improvement of characteristic properties in various materials by doping [2][3][4][5]. Among the multifarious nanomaterials of transition-metal oxides, cupric oxide (CuO) with a narrow bandgap of 1.2-1.9 eV has attracted much interest due to its unique properties.…”

An Ultrahigh Sensitivity Acetone Sensor Enhanced by Light Illumination

“…In the past decades, metal semiconductor oxides have attracted much attention for their high sensitivity and stability toward reducing gases. Examples such as TiO 2 [ 11 , 12 , 13 ], NiO [ 14 , 15 ], ZnO [ 16 , 17 , 18 , 19 ], Co 3 O 4 [ 20 ], Fe 2 O 3 [ 21 , 22 ], WO 3 [ 23 , 24 , 25 ], and SnO 2 [ 26 , 27 , 28 , 29 , 30 ] are reported as acetone sensors with good performance. In recent years, the perovskite structure (ABO 3 ) also showed good sensitivity, stability and selectivity toward acetone, with examples such as LaFeO 3 [ 31 , 32 ] Yb 1−x Ca x FeO 3 [ 33 ] LaNi 1−x Ti x O 3 [ 34 ] SmFeO 3 [ 35 ], SmFe 1−x Mg x O 3 [ 36 ], NdFeO 3 [ 37 ] and La 0.75 Ba 0.25 FeO 3 [ 38 ].…”

Synthesis of Co-doped SnO2 nanofibers and their enhanced gas-sensing properties

“…Recently, the research related to gas sensor has intensively carried out due to its important role in environmental monitoring and personal safety [2][3][4]. Until now, several kinds of gas sensors have been developed based on different sensing materials.…”
