| titleOfInvention | Method for hydrogen production by electrochemically decomposing water by using surface autocatalytic effect of superfine 3C-SiC nanocrystals |
| abstract | The invention relates to a method for hydrogen production by electrochemically decomposing water by using a surface autocatalytic effect of superfine 3C-SiC nanocrystals. The method is characterized in that: a suspension of the superfine 3C-SiC nanocrystals is prepared by adopting a chemical etching method, the suspension is dropwise coated on a conductive glassy carbon substrate to obtain a superfine 3C-SiC nanocrystal membrane electrode, and excellent electrocatalytic activity is shown when the electrode is applied to the reaction for the hydrogen production by electrochemically decomposing the water. The catalytic activity is generated because the surfaces of the superfine 3C-SiC nanocrystals can dissociate water molecules in the process of surface autocatalysis so as to form a structure that -H and -OH are respectively bonded to the two ends of a Si-Si dimer, and the activation potential barrier in water decomposition can be remarkably lowered due to the autocatalytic effect. When the electrode is applied to the reaction for the hydrogen production by electrochemically decomposing the water, the excellent electrocatalytic activity is shown at a low voltage, so that the hydrogen production by decomposing the water under the action of electrocatalysis and photoelectrochemical synergy is achieved. |
