| Abstract: | Visible light photothermalcatalytic water splitting for hydrogen generation on TiSi2 series catalyst was investigated systematically under high pressure.It was found that hydrogen generation rate of photocatalytic water splitting was improved significantly with the increase of pressure.Beneficial to water decomposition reaction of hydrogen production by addition of NaOH or Na2CO3,to some extent,hydrogen generation rate increased with the increase of NaOH or Na2CO3 concentration.The results also showed that ... |
