Structural, Topography, and Optical Properties of Ba‐Doped Mn3O4 Thin Films for Ammonia Gas Sensing Application

“…The optical absorbance of pure and Ba‐doped thin films were measured by UV‐Vis‐NIR spectrophotometer (Metertech SP‐8001) with wavelength ranging from 400 to 1100 nm, Figure shows the absorbance spectra of the sprayed films as a function of wavelength, it can be observed the absorbance changes with Ba concentration and the maximum absorbance is achieved in Mn 3 O 4 :Ba1% films, this may be due to the porosity nature and the multiple reflections within the pores of the surface, similar findings are reported literature …”

Co3O4–Ag photocatalysts for the efficient degradation of methyl orange

“…[10][11][12][13][14] Hence, various new types of semiconductors have been developed as photocatalysts to solve this problem. [15][16][17][18][19][20][21][22][23][24][25][26] Among these, Co 3 O 4 is a potential material for many applications because of its excellent electronic and magnetic properties. 6,27,28 For example, it can be used as a material for supercapacitors due to its high theoretical capacitance ($3560 F g À1 ).…”

Narrow-bandgap Nb2O5 nanowires with enclosed pores as high-performance photocatalyst

“…Among the many varieties of 1D nanostructures, porous nanowires are particularly interesting, not only for the unique porous structure and physical chemical properties, but also for their outstanding performance in optics and electronics [15][16][17][18][19][20][21][22][23]. So far, many groups have reported the growth of porous 1D semiconductor nanostructures and studied their exceptional performance, such as porous ZnO nanowires with superior photocatalytic activity [24], CdS nanosponges showing high activity for RhB photo-degradation under visible light due to the accessibility of both inner and outer surfaces through the pores in the walls [25], porous TiO 2 nanotubes with improved photocatalytic efficiency due to their larger specific surface areas [26], porous In 2 O 3 nanowires with excellent gas sensing properties to H 2 S benefiting from surface adsorption and the sulfuration [27], porous SnO 2 nanowire bundles consisting of interconnected nano-crystallites with a remarkable photocatalytic effect for the degradation of RhB and a high de-lithiation capacity [15], and porous Co 3 O 4 nanowires with high sensitivity to carbon monoxide because porous structure increases the surface reactive sites and facilitates the diffusion of target gases [28].…”
