摘要:The present invention discloses a phosphorus-activated platinum-based catalyst, a preparation method therefor, and an application thereof. The preparation method comprises the following steps: 1) synthesis of a platinum-based catalyst: adding a first solvent, deionized water, a surfactant, and a platinum salt solution into a carbon carrier, and uniformly stirring at room temperature to obtain a base mixed solution; and then rapidly adding a reducing agent into the base mixed solution, and stirring at room temperature for 0.5-24 h (not including 24 h), a solid product obtained after stirring ends being the platinum-based catalyst; and 2) phosphating of the platinum-based catalyst: adding the platinum-based catalyst prepared in 1) and a phosphate source into a second solvent, and then refluxing at 30-180°C for 5-12 under the atmosphere protection, a solid product obtained after refluxing ends being the phosphorus-activated platinum-based catalyst. The preparation method for the phosphorus-activated platinum-based catalyst of the present invention is simple, low in costs, and high in catalytic activity.
