The copper-catalyst compound, name is Bis(acetylacetone)copper,cas is 13395-16-9, mainly used in chemical industry, its synthesis route is as follows.

General procedure: The monodisperse CuPd alloy NPs with composition controlwere synthesized by using a modified version of our estab-lished recipe for the CoPd alloy NPs [14]. In a typical synthesis of Cu75Pd25NPs, copper(II) acetylacetonate (0.35 mmol, 90 mg)and palladium(II) acetylacetonate (0.1 mmol, 31 mg) were dis-solved in 3 mL of OAm in a 10 mL of glass vial. In a four-necked glass reactor that allows to study under inert atmosphere,200 mg of MB was dissolved in 3 mL of OAm and 7 mL of 1-octadecene at 80C under magnetic stirring. Next, the metal precursor mixture was quickly injected into the reactor under argon environment. The reaction was then proceed for 1 h before cooled down to room temperature. Then, the colloidal NPs mixture was transferred into two separate centrifuge tubeand acetone/ethanol (v/v = 7/3) was added into the tubes. TheNP product was separated by centrifugation at 8500 rpm for10 min.

Bis(acetylacetone)copper, cas is 13395-16-9, it is a common heterocyclic compound, the copper-catalyst compound, its synthesis route is as follows.

A mixture of 1.05 g (4 mmol) Cu(AcAc)2, 0.44 g (2 mmol) Zn(OAc)2, 0.38 g (2 mmol) SnCl2, and 20 ml OLA were added into a 100 ml three-neck round-bottom reaction flask connected to a nitrogen gas cylinder. The mixture solution was always stirred vigorously in the flask purged with high pure N2 gas (99.999%), during the whole synthesis. After heated at 130 C for 30 min, the mixture solution became brownish. The brownish solution was injected with 8 ml of sulfur – OLA solution (1 M), then heated at the reaction temperature T reaction 240-280 C for 1 h. When its color changed from dark brownish into blackish, the mixture solution (or product) was cooled down to room temperature (RT) and added with 15 ml of toluene for dispersing by sonication. To washing or purifying the product, 40 ml of ethanol was firstly added to let the nanoparticles flocculate and precipitate; then precipitates of nanoparticles were collected by centrifuging at 4000 rpm for 20 min and the supernatant liquid was removed; the collected precipitates were dispersed in toluene again by sonication; then ethanol was added for precipitates, new precipitates were collected again by centrifuging. The above process was repeated for three times. The final precipitates (or CZTS nanoparticles) were divided into two parts: (1) CZTS nanoparticles dispersed in toluene to form a stable ink solution and (2) CZTS power dried in a vacuum oven.
