The template-assisted wet-combustion synthesis of copper oxide nanoparticles on mesoporous network of alumina nanofibers

Template-Assisted Wet-Combustion Synthesis of Fibrous Nickel-Based Catalyst for Carbon Dioxide Methanation and Methane Steam Reforming

“…Notably, the wet-combustion method can be used to decorate nanofibers with different metal oxides or even provide controllable interaction between a core and a shell. , However, for control of the homogeneous distribution of metal oxides over the fibers, it is important to choose a suitable metal salt precursor and a fuel, which not only serves as a source of energy but also greatly influences the reaction pathway. , Specifically, infiltrating the mesoporous network of alumina by nickel nitrate aqueous solution without adding any fuel and treating at similar condition (400 °C, 30 min) results in nonhomogeneously “clustered” NiO nanoparticles detached to the fibers as demonstrated in Figure . The formation of ternary oxide and uniformly distributed NiO nanoparticles is favored when glycine is added into the initial reactive solution.…”

“…The temperature−time history of the synthesis process was recorded by highly accurate MPAC IGAR 12-LO digital 2-color pyrometers with a fiber optic and a response time of 2 ms. The schematic representation of the process of wet-combustion synthesis of the Ni-based catalyst is given in Figure 2 and detailed in ref 23. The prepared catalyst is denoted as Ni/ANF(F).…”

Biosynthesis and Fabrication of Copper Oxide Thin Films as a P-Type Semiconductor for Solar Cell Applications

“…CuO which is a semiconducting compound located in group I-IV of the periodic table, has over the years been of much interest as a result of the electrical and optical properties it possesses [2]. Additionally, its high optical absorption rate [5,6], excellent electrical conductivity [7], non-toxic nature [8], production efficiency, and more especially, its low cost of manufacturing have resulted in the material drawing a lot of attention from industries. Furthermore, as a result of its powerful solar absorbance and minimal thermal emittance [9], CuO has been acknowledged to be an attractive solar absorber, while Cu 2 O is a very favorable option for solar cell applications due to its suitability for photovoltaic energy conversion [10,11].…”
