“…The two major peaks of Cu 2p 3/2 and Cu 2p 1/2 are located at 934.2 and 954.0 eV, respectively. The splitting 18,19 energy is 19.8 eV, which agrees well the literature reported value 28 and indicates the formation of Cu 2+ . The satellite peakson the high energy side, arised from the shake-up transition by a ligand metal 3d charge transfer, also confirm the presence of Cu 2+ .…”

“…9 Outlet profiles of CO in the propene oxidation over CuCo2O4, Co3O4 and bare mesh. of 272 °C, 19 CuCo 2 O 4 has more application prospects than CuO by considering the higher thermal stability. It is worth mentioning that the magnitude order of T 50 for CuO, CuCo 2 O 4 and Co 3 O 4 follows the order of bandgap.…”

“…PSE-CVD was used to synthesize the copper-cobalt oxides and the phases, composition, morphology, thermal and optical properties were comprehensively characterized with Xray diffraction (XRD), emission FTIR, X-ray photoelectron (XPS), UV-Visible and Helium ion microscopy (HIM). It should be mentioned that part of the information is provided in 19 for pure CuO. The catalytic potential of the synthesized copper-cobalt oxides was studied for the total oxidation of CO and propene with online absorption FTIR.…”

In situ emission and absorption FTIR methods were employed to characterize the spatially resolved structure of binary Co-Cu oxides for low-temperature oxidation of CO and propene. Co-Cu oxide catalysts were controllably synthesized by pulsed-spray evaporation chemical vapor deposition. XRD, FTIR, XPS, UV-vis and helium ion microscopy (HIM) were employed to characterize the as-prepared thin films in terms of structure, composition, optical and thermal properties as well as morphology. In situ emission FTIR spectroscopy indicates that Co3O4, CuCo2O4 and CuO are thermally stable at 650, 655 and 450 °C, respectively. The catalytic tests with absorption FTIR display that the involvement of Co-Cu oxides can initiate CO and C3H6 oxidation at lower temperatures. The results indicate that in situ emission and absorption FTIR are useful techniques to explore the thermal properties and catalytic performance of functional materials, allowing many potential applications in tailoring their temporally and spatially resolved structure-property relationships.

“…It promotes enhanced electrocatalytic activity towards oxygen and hydrogen peroxide reduction reactions in conventional electrochemical processes, due to the enlarged surface roughness and to the presence of new active sites [14][15][16]. Films of CuO on stainless steel mesh also exhibit efficient catalytic activities for propene oxidation [17] while copper phthalocyanine performs as platinum catalysis for oxygen reduction reaction in MFCs [18]. With regards to the capacitance of the electrodes, nanocrystals of copper can function with mesoporous activated carbons similarly as noble metals such as Pt and Pd, giving rise to substantial enhancement of the capacitance of carbonaceous electrodes [15].…”

This chapter is an update of part of a review published by our group elsewhere in Patai's Series; in addition, in this volume, chapters present the recent advances in the deposition of metals and oxides of main‐group metals and rare‐earth elements, all derived from metal enolates. Metal oxides are essential as common inorganic crude materials, possessing a manifold portfolio of applications because of their singular physical and chemical properties. Metal oxides are formed by straight vaporization from metal oxide sources, by evaporation of metals in an oxidizing atmosphere, or via wet chemistry, for example, the sol‐gel process. Their industrial use includes protective coatings, electrical insulator materials, gate oxides, transparent conductors, piezoelectric materials, battery electrode materials, electrochromic devices, optical filters, laser‐active media, wide‐bandgap semiconductors, solar absorbers, and many others.
