摘要

摘要: 光催化析氢反应被认为是最有前途的制氢方法之一。炭材料是大规模、低成本光解水制氢的潜在催化材料，然而目前其光催化活性仍旧较低，还不足以满足实际应用要求。本文以廉价易得的泥炭为原料，通过与尿素共炭化制备了一种氮掺杂多孔炭，作为光热辅助可见光催化剂，利用炭材料优异的光热效应提高体系温度，进而提高光催化活性。在可见光照射下，这种泥碳基炭材料可使体系温度在15 min内从室温提高至55 °C，光催化活性提高25%左右。系统考察了结晶度与氮掺杂含量对炭材料光催化性能的影响，发现在光热效应的促进下，N含量为4.88 at%且有适宜结晶度的炭材料表现出优异的光催化性能，析氢速率达到75.6 μmol H₂ g⁻¹ h⁻¹。

Abstract: Photocatalytic H₂ evolution is considered one of the most important processes for H₂ production. Carbon materials are potential candidates for large-scale and cost-effective photocatalytic water splitting, yet their activity needs to be further improved. We report the synthesis of nitrogen-doped porous carbons using peat moss as a precursor and urea as a nitrogen source. The properties of carbons as photothermal-assisted visible-light photocatalysts were investigated. Due to the photothermal effect, the system temperature increased quickly to 55 °C in 15 min under visible light irradiation, which subsequently helps increase the photocatalytic activity by about 25%. It has been found that the crystallinity and nitrogen content of the carbon materials can be changed by changing the carbonization temperature, and these have an impact on their photocatalytic activity. A peat-derived carbon carbonized at 800 °C, with a N content of 4.88 at.% and an appropriate crystallinity has an outstanding photocatalytic activity with a high H₂ evolution rate of 75.6 μmol H₂ g⁻¹ h⁻¹ under visible-light irradiation.
