Abstract
The invention discloses a preparation method of a hydrogen elimination material. The method comprises the following steps: 1, oxidizing a carbon nanomaterial, and then activating and alkynylating to obtain an alkynylated carbon nanomaterial having a hydrogen storage function; 2, dispersing the alkynylated carbon nanomaterial in a solvent, adding a precious metal salt solution, heating and stirring; then, adding a reducing agent solution, and continuing to stir to obtain an alkynylated carbon nanomaterial-loaded nano-precious metal hydrogen elimination material. According to the preparation method, the carbon nanomaterial having a hydrogen storage function is firstly oxidized, and is then subjected to activation and alkynylation, so that the alkynylated carbon nanomaterial having the hydrogen storage function is obtained; the alkynylated carbon nanomaterial-loaded nano-precious metal hydrogen elimination material is then prepared by using an in-situ reduction method. In the alkynylatedcarbon nanomaterial-loaded nano-precious metal hydrogen elimination material, the carbon nanomaterial has the hydrogen storage function, and the nano-precious metal acts as a catalyst and can enable the unsaturated alkyne group to react with hydrogen at the normal temperature, so that a hydrogen elimination function is realized.
