| titleOfInvention | Flower-shaped nitrogen-doped carbon-spinel microsphere catalyst with high specific surface area and preparation method and application thereof |
| abstract | The invention discloses a flower-shaped nitrogen-doped carbon-spinel microsphere catalyst with high specific surface area, and a preparation method and application thereof. The method comprises the following steps: uniformly mixing ethanol, ammonia water, tetraethyl silicate and dopamine hydrochloride, centrifuging and calcining to obtain nitrogen-doped carbon-silica particles, adding the nitrogen-doped carbon-silica particles into the water, uniformly mixing, adding nitrate, urea and sodium hydroxide, and uniformly mixing to obtain a mixed solution; heating, centrifuging and calcining to obtain the flower-shaped nitrogen-doped carbon-spinel microsphere catalyst with high specific surface area. The preparation method provided by the invention has a simple process, adopts dopamine hydrochloride as a carbon source, enables the silicon dioxide microspheres to have rich pore channel structures and large skeleton strength, can change the electron distribution of the carbonaceous material by nitrogen doping, and provides possibility for ions to diffuse to micropores. The active substance of the catalyst is spinel type, and no noble metal is used; the catalyst has the advantages of low preparation cost, large specific surface area, rich surface active sites, strong stability, high catalytic activity and the like. |
