• be discussed later. The catalytic activity of the CoNiZIE catalyst in the selective hydrogenation of citral to unsaturated alcohols (geraniol and nerol) can be attributed to a synergistic interaction between cobalt and nickel species. These active species are likely associated with isolated cations

• the catalysts, the bimetallic CoNiIE material, prepared by IE, emerged as the most promising. It was the only catalyst to exhibit activity for the hydrogenation of citral to form unsaturated alcohols, suggesting a synergistic interaction between cobalt and nickel species. The active species are likely

• ]. Taking the CeO2–CuO catalyst as a typical example, the improved catalytic activity is closely related to the synergistic interaction between copper and ceria, which promotes the exchange of charges between Ce4+/Ce3+ and Cu2+/Cu+ and leads to faster oxidation and reduction than that of the corresponding

• , thus, the facilitation of synergistic interaction between two components are necessary to optimize the catalytic performances. The unique structure and texture of CeO2-based catalysts is also associated with high activity and stability in the catalytic reaction. For instance, rod-like CeO2–CuO

• nanocubes, show higher catalytic activity towards OER in alkaline medium. This is due to the presence of the low surface energy crystal plane of Co3O4 NPs and their synergistic interaction between N-doped because graphene helps to tune the properties of the OER electrocatalyst.
