Effect of molar ratio of citric acid to metal nitrate on the structure and catalytic activity of NiO nanoparticles

Enhancing catalytic activity and stability for CO2 methanation on Ni@MOF-5 via control of active species dispersion

“…The binding energies at 852.6, 870.0, 852.7 and 870.3 eV could be assigned to Ni2p 3/2 , Ni2p 1/2 , Ni2p 3/2 and Ni2p 1/2 , respectively. 16 They indicated that the Ni species for 10Ni@MOF-5 and 10Ni/SiO 2 was metallic Ni. In addition, the peak intensity of Ni2p (10Ni@MOF-5) was strong, indicating that the Ni species of 10Ni@MOF-5 was uniformly dispersed in the frameworks.…”

Toward Industrial Production of a High-Performance Self-Powered Ultraviolet Photodetector Using Nanoporous Al-Doped ZnO Thin Films

“…It is thought that the nanoporosity present in the continuous films is due to the ease of releasing volatile solvents (e.g., acetic acid and 2-methoxyethanol) from the spin-coated thin films during annealing. Another reason is the out-diffusion of gases produced by the thermal decomposition of metal citrate complexes (e.g., N 2 and CO 2 ), as follows: − …”
