Gold‐Nanoparticles‐Decorated ZrO2‐CuO Nanocomposites: Synthesis, Characterization and A Novel Platform for Electrocatalytic Formaldehyde Oxidation

“…By cyclic voltammetry, Au nanoparticles at different cycle numbers (2–10 cycles) were deposited on the surface. As it is known, metal nanoparticles modified on metal oxides create oxygen vacancy and show a significant enhancement in formaldehyde oxidation [25] . As the number of loops increased, it was observed that the current increased due to this effect.…”

“…As it is known, metal nanoparticles modified on metal oxides create oxygen vacancy and show a significant enhancement in formaldehyde oxidation. [25] As the number of loops increased, it was observed that the current increased due to this effect. However, when the number of cycles exceeded 7, the current decreased again.…”

“…Especially in studies on formaldehyde oxidation, it is known that adding metal nanoparticles to metal oxides creates oxygen vacancies in the electrode material and catalyses formaldehyde oxidation. For this purpose, it is seen that different metals such as Pt, Pd, Au are modified on electrode surface for formaldehyde oxidation [25,26] …”

“…For this purpose, it is seen that different metals such as Pt, Pd, Au are modified on electrode surface for formaldehyde oxidation. [25,26] This study presents the electrochemically prepared Au nanoparticles modified ZrO 2 -CuO catalysts for investigating formaldehyde oxidation in alkaline media. The easily preparing stable composite electrode surface was characterised by X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and electrochemical impedance spectroscopy (EIS).…”

Non-noble Nickel-Modified Covalent Organic Framework for Partial Hydrogenation of Aromatic Terminal Alkynes

“…Overall, in the construction of semihydrogenation of terminal alkynes, non-noble metal heterogeneous catalysts are proved to be low-cost alternatives to noble metal catalysts. In addition to the metal catalytic center, it is still essential to choose the suitable catalytic support, which could immobilize metal nanoparticles and modify its dispersion capability and electron effects. − Furthermore, the interaction between the active metal and support materials plays a crucial role in enhancing the comprehensive catalytic activity of the catalysts. − Therefore, it is highly desired to rationally design high-efficiency non-precious metal-supported catalysts and have an in-depth understanding of the catalytic active sites for efficient hydrogenation of alkynes to alkenes.…”
