“…Also, it is employed for the design and fabrication of nanosensors, nanolasers, switches and transistors [21,22] and is good selective solar absorber since it possesses high solar absorbency and low thermal emittance [23]. A CuO is widely used as a pigment in ceramics, as dispersed nanoparticles in nanofluids to increase thermal conductivity [24], as catalyst in the abatement of NO x [25], superconductor [26], gas sensors [27], magnetic storage media [28], lithium-ion electrode materials [29], solar cells [30], field transistors and biosensors, etc. [31,32].…”

“…New catalytic materials containing copper oxide and niobium pentoxide supported on silica-alumina (CuO/ Nb 2 O 5 /SiO 2 -Al 2 O 3 ) have recently been characterized under distinct preparation conditions, oxide loadings (including sub-monolayer, monolayer and above-monolayer coverage) and calcination temperatures [14]. A strong influence was observed for the CuO over Nb 2 O 5 crystallites, according to preparation method [10,14].…”

“…A strong influence was observed for the CuO over Nb 2 O 5 crystallites, according to preparation method [10,14]. The most promising materials contained a 1:1 oxide ratio (CuO:Nb 2 O 5 ), were prepared by simultaneous impregnation, and calcined at 300°C.…”

“…En la figura 2 (a), correspondiente al KNN puro, se presenta una banda alrededor de ~550 cm -1 que pertenece al modo vibracional del NaNbO 3 y/o KNbO 3 [16], la banda alrededor de ~768 cm -1 está asociada al modo vibracional del enlace Nb-O del octaedro NbO 6 [17] y la banda alrededor de ~662 cm -1 corresponde a la vibración del octaedro NbO 6 , indicando la existencia de la fase perovskita [18,19]. Cuando el KNN se dopa con 0.5 % de BLFO (figura 2 (b)), las bandas anteriormente mencionadas experimentan un corrimiento y aparecen nuevas bandas.…”
