“…These materials have been shown to be excellent adsorbents for the removal of MB, when used together with Tween-80 to produce CuO nanostructures. 35,36 This dye is toxic if swallowed or when it comes into direct contact with skin. It can also cause damage to various human organs, e.g., eyes, and the central nervous system.…”

“…TGA spectra for the three products were investigated at temperatures up to 800 °C in air at a heating rate 5 °C min –1 as shown in Figure.S4. For pure CuO, it has observed that the initial weight loss about 4.7% at 200 °C could be due to the chemisorbed water . In the temperature range 282–398 °C, the second weight loss is about 22%, which might be due to the consequent evaporation process of CuO .…”

The development of lithium-ion batteries using transition metal oxides has recently become more attractive, due to their higher specific capacities, better rate capability, and high energy densities. Herein, the in situ growth of advanced mesoporous CuO/O-doped g-C3N4 nanospheres is carried out in a two step hydrothermal process at 180 °C and annealing in air at 300 °C. When used as an anode material, the CuO/O-doped g-C3N4 nanospheres achieve a high reversible discharge specific capacity of 738 mAhg–1 and a capacity retention of ∼75.3% after 100 cycles at a current density 100 mAg–1 compared with the pure CuO (412 mAhg–1, 47%) and O-doped g-C3N4 (66 mAhg–1, 53%). Even at high current density 1 Ag–1, they exhibit a reversible discharge specific capacity of 503 mAhg–1 and capacity retention ∼80% over 500 cycles. The excellent electrochemical performance of the CuO/O-doped g-C3N4 nanocomposite is attributed to the following factors: (I) the in situ growing CuO/O-doped g-C3N4 avoids CuO nanoparticle aggregation, leading to the improved lithium ion transfer and electrolyte penetration inside the CuO/O-doped g-C3N4 anode, thus promoting the utilization of CuO; (II) the porous structure provides efficient space for Li+ transfer during the insertion/extraction process to avoid large volume changes; (III) the O-doping g-C3N4 decreases its band gap, ensuring the increased electrical conductivity of CuO/O-doped g-C3N4; and (IV) the strong interaction between CuO and O-doped g-C3N4 ensures the stability of the structure during cycling.

“…Among the different these materials, copper oxide (CuO) is hopeful p-type semiconductor metal oxide material with band gap energy of about 1.4 eV and monoclinic crystalline form [4,5]. Due to its significant properties, such as abundance, economic, nontoxic, well electrical and optical characteristic and perfect thermal stabilities, CuO films are widely used in many different applications, such as gas sensors, solar cells, photocatalysis, lithium batteries, biosensors and transistors [6][7][8][9][10].…”

Abstract:In this study, we informed a systematic approach to obtain CuO films with and without TX-100 surfactant by the SILAR procedure. Morphological, structural and optical features of the CuO films were researched by metallurgical microscope, scanning electron microscopy, X-ray diffraction analysis and ultraviolet-visible spectrophotometry respectively with respect to concentrations of TX-100 agent. Metallurgical and scanning electron microscope photographs displayed that the morphology of the film surface was impressed by surfactant TX-100. X-ray diffraction patterns verified that all CuO films have monoclinic crystal lattice structure with preferential orientations of ( 1 11) and (111) planes. Ultraviolet-visible spectra demonstrated that the optical bandgap and transmittance values of the films were altered with TX-100 content. Nanoyapılı CuO Filmlerin Fiziksel Performansının Surfaktan TX-100 Yoluyla GeliştirilmesiAnahtar Kelimeler Bakır Oksit (CuO), Triton X-100, XRD, Bant AralığıÖzet: Bu çalışmada TX-100 surfaktan içeren ve içermeyen CuO filmler sistematik bir yaklaşım gözeterek SILAR yöntemi yardımıyla elde edilmişlerdir. Elde edilen CuO filmlerinin morfolojik, yapısal ve optik özellikleri, TX-100 konsantrasyonuna bağlı olarak sırasıyla metal mikroskobu, taramalı elektron mikroskobu, X-ışını difraksiyon analizi ve ultraviyole-görünür spektrometresi ile incelendi. Metal ve taramalı elektron mikroskobu fotoğrafları, film yüzey morfolojisinin yüzey aktif madde TX-100 tarafından etkilendiğini ortaya koydu. X-ışını kırınım desenleri, tüm CuO filmlerinin (1 11) ve (111) düzlemlerin tercihli yönelimleriyle monoklinik kristal kafes yapısına sahip olduğunu doğruladı. Ultraviyole -görünür spektrum, filmlerin optik bant boşluğu ve geçirgenlik değerlerinin TX-100 içeriği ile değiştiğini gösterdi.
