成果简介	NOVELTY - Co-precipitation method for coating silver-doped copper oxide, involves dissolving 3.2 g copper sulfate pentahydrate in deionized water (DI) (100 mL) under stirring for 30 minutes to complete dissolution. The solution of 0.2 M silver nitrate hydrate (0.679 g) in 20 ml DI is added. The different volume ratios of 0%, 1%, 3%, 5%, and 7.5% relative to copper sulfate pentahydrate are mixed to form precipitate and marked as copper (II) oxide, 1 Ag% -copper (I) oxide, 3 Ag% -copper (I) oxide, 5 Ag% -copper (I) oxide, and 7 Ag% -copper (I) oxide, respectively. The products are filtered and cleaned with DI water multiple times. Before the deposition of active material on a nickel foam, the foam is cleaned by using sonication in isopropanol alcohol for 30 minutes to eradicate the oxide surface. USE - Co-precipitation method for coating silver-doped copper oxide for electrochemical water oxidation. ADVANTAGE - The optimal silver-copper oxide nanogranules have improved electrocatalytic properties as bifunctional electrocatalysts for overall water oxidation and may provide a new route for realistically creating heterogeneous interfaces to increase their electrochemical performances, which may help to speed up the progress of nonprecious electrocatalysts for overall water oxidation. DETAILED DESCRIPTION - Co-precipitation method for coating silver-doped copper oxide, involves dissolving 3.2 g copper sulfate pentahydrate in deionized water (DI) (100 mL) under stirring for 30 minutes to complete dissolution. The solution of 0.2 M silver nitrate hydrate (0.679 g) in 20 ml DI is added. The different volume ratios of 0%, 1%, 3%, 5%, and 7.5% relative to copper sulfate pentahydrate are mixed to form precipitate and marked as copper (II) oxide, 1 Ag% -copper (I) oxide, 3 Ag% -copper (I) oxide, 5 Ag% -copper (I) oxide, and 7 Ag% -copper (I) oxide, respectively. The products are filtered and cleaned with DI water multiple times. Before the deposition of active material on a nickel foam, the foam is cleaned by using sonication in isopropanol alcohol for 30 minutes to eradicate the oxide surface. To form an ink of the active material, electrocatalyst powder (5 mg) besides 5 wt.% Nafion solution (40 mL) are mixed in 350 mL DI water (16MU cm) and 150 mL alcohol mixtures under ultrasonication (1 hour). The formed homogeneous ink (40 mL) is drop-casted on the nickel foam substrate with an area of 1 cm 2. The obtained electrode is dehydrated in a vacuum oven at 60?oC for 1 hour.
