| titleOfInvention | Preparation method of indole-modified macroporous carbon supported transition metal catalysts |
| abstract | The invention relates to an oxygen electrochemical reduction catalyst, and aims to provide a preparation method of indole-modified macroporous carbon supported transition metal catalysts. The method comprises the following steps of: adding hydrophilic nano CaCO3 and a carbon source material into deionized water, and carrying out ultrasonic vibration mixing on the obtained mixture; heating the mixture to evaporate water, and then solidifying for 6 hours at a temperature of 160 DEG C; carrying out constant-temperature carbonization on the solidified product under nitrogen; washing a carbonized product sequentially by using a hydrochloric acid, a sodium hydroxide solution and deionized water, and carrying out constant-temperature drying on the obtained product so as to obtain a macroporous carbon material; and after the macroporous carbon material is crushed, adding indole as a modified material, adding an aqueous solution of transition metal nitrates, sulfates or chlorides into the obtained object, after the obtained product is reacted, filtering, cleaning and drying the obtained product so as to obtain an indole-modified macroporous carbon supported transition metal catalyst. The method disclosed by the invention is simple in synthesis process and easy to operate, and a necessary high-temperature calcination process required by the preparation of general catalysts is not required. The synthesis time of catalysts can be greatly shortened. Catalyst are good in electrical conductivity, and an indole modified layer increases the activity and stability of catalysts, and therefore, the catalysts are especially applicable to large-current working conditions. |
