All the chemicals were of analytical grade and were used without further purification. Firstly, 1.8 g of glucose (Sinopharm Chemical Reagent Co., LTD. AR), 0.582 g of Co(NO3)2.6H2O(Sinopharm Chemical Reagent Co., LTD. AR) and 15 g of NaCl (Tianjin Guangfu Technology Development Co., LTD. AR)were dissolved in 50 ml of deionized water under magnetic stirring until a transparent blue solution was obtained. Then, the solution was transfered into a drying oven and dried at 80 oC for 24 h. The dry block of crystal was ground to fine powder in an agatemortar. The composite powder was heated in a tubular vacuum furnace at 750 oC for 2 h under flowing N2. Finally, it was annealed again at 300 oC for 4 h under air. Once cooled to room temperature, the as-synthesized black powder was washed by deionized water several times to remove NaCl, and then Co3O4@C@PGC nanosheets were obtained. For comparison, Co3O4/C composites were also synthesized by carbonizing the mixture of Co(NO3)2·6H2O and glucose without adding NaCl at the same conditions. Meanwhile, Co3O4 NPs were also synthesized by sintering Co3O4@C@PGC nanosheets at 600 oC for 2 h in air. And PGC nanosheets were obtained by immersing Co3O4@C@PGC nanosheets in plenty of nitric acid for 4 h at 70 oC with magnetic stirring to remove the Co3O4 NPs.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
