Exploring the relationship between the structure of active site and the activity in molecular level and investigating the reason for deactivation are extremely important in designing the highly active catalyst. In this paper, new self‐assembly Schiff‐base Pd/Cu nanosheets supported on the surface of graphene oxide (GO) (called as GO@Hpmaba‐Pd/Cu) were fabricated and characterized. Among them, GO@Hpmaba‐Pd0.2/Cu0.8 exhibited a high activity with a TOF value of up to 95,357 h−1 and substrate suitability in Suzuki cross‐coupling reaction. GO@Hpmaba‐Pd0.2/Cu0.8 could be reused at least 13 times. GO@Hpmaba‐Pd0.2/Cu0.8 was a heterogeneous catalyst and the catalysis occurred on the surface. The truly active sites included Pd/PdO/CuO/PdCu3 formed in situ on the surface of the hetero‐organometallic Pd/Cu nanosheet during catalysis. The synergistic effects among these active sites could be described as that the electrons transferred from GO to CuO (PdO) or to Pd via ligand (Hpmaba) and subsequently electrons transferred from CuO (PdO) to Pd. These made more electron negative palladium, enhancing the oxidation addition between palladium and aryl halide and prompting the activity. The deactivation of catalyst was mainly caused by some destroyed organometallic in the nanosheet, residues adsorbed on catalytic surface, loss of active Pd due to the leaching with increase of recycling, and the aggregation of active metals.

Background: Magnetic nanoparticles are the main source of synthesis and design of magnetic nanocatalysts, which are obtained from iron salts by chemical co-precipitation method. Objective: The main goal of this research is to investigate the absorption, release and antibacterial properties of magnetic nanocatalysts with silica coating and silica/amine linker. Methods: The structure of the obtained nanocatalyst is detected by several analyzes such as SEM, TEM, EDX and IR. Results: Here is reaction between the ampicillin 10 µl (25 µg/ml) and the Fe3O4@SiO2 and Fe3O4@SiO2/NH magnetic nanocatalyst 200 mg (2 mole%), under 25°C and double distilled water. In this way, the amount of absorbed ampicillin on MNPs@silica/amine structure in covalent is more than MNPs@silica structure in non-covalent bonding, i.e. 85 to 65%, but the rate of release in non-covalent is above 90%, but in covalent is less than 80%. Also, the bactericidal properties of nanocatalysts have been tested separately at a temperature of 37 degrees for the non-covalent type are more than 80% compared to Covalance form is 70%. Conclusions: The overall result was that the percentage efficiency of the absorption/release reaction in the non-covalent bonding state was much better and about 10% more release.
