Research advances of MOF-based catalyst for photohydrolysis for hydrogen production

  • 摘要: 随着能源枯竭和环境污染问题日益严重,人们不得不将目光转向更加清洁环保的氢能源。光解水制氢技术是一种获取氢能源经济且清洁的理想方式,通过光催化手段将太阳能转化为化学能也是一种很有前景的技术手段。然而如何选取高效、经济的光催化剂是制氢最关键的环节。金属-有机框架(Metal-organic frameworks, MOFs)由于比表面积大、孔尺寸可调节、结构易于修饰及活性位点丰富等特点,使其成为光解水制氢理想的光催化剂候选材料。国内外学者就MOFs光解水制氢开展了大量的研究,并且取得了丰硕的成果。本论文综述了MOF基材料作为催化剂在光解水制氢领域的研究进展,总结了MOFs作为催化剂的优点和局限性,并对MOFs及其相关材料在光催化水解制氢领域的发展前景提出展望,以期对未来研究提供参考。

     

    Abstract: The increasingly serious energy exhaustion and environmental pollution accelerates the development of clean hydrogen energy. Water splitting via photocatalysis technology provides an economical and clean way for the hydrogen production, converting solar energy into chemical energy through photocatalytic means is also a promising technical means. The rational selection of photocatalyst is the critical step for obtaining hydrogen energy in an efficient and economical way. Featuring the traits of large specific surface area, adjustable pore size, easy structure modification and abundant active sites, metal-organic frameworks (MOFs) are ideal candidates for photocatalytic hydrogen production scientists from domestic and foreign have carried out numerous researches on the water splitting with MOF-based photocatalysts. Currently, fruitful progresses have been achieved. In this paper, the state-of-the-art advances for the MOF-based materials as catalysts in the field of hydrogen production from splitting water was reviewed, and the advantages and limitations of MOFs as catalysts were summarized. The development prospect of MOFs and related materials in the field of photocatalytic hydrogen production was proposed, providing a valuable guideline for developing future photocatalysts.
