摘要:

单原子催化剂具有独特的物理和化学特性,在一些化学反应中优于传统催化剂,单原子催化技术已取得了长足的进步,有望成为下一代催化剂。文章追溯了单原子催化剂的概念起源,并采用文献计量学和专利统计学方法,运用多维指标分析了单原子催化领域相关论文和专利。结果表明,单原子催化基础研究和开发应用研究均处于技术上升期,中国在单原子催化领域处于国际引领地位。在基础研究中,中国科学院、清华大学、美国能源部表现出了超强实力;在开发应用研究中,尽管中国专利的申请量占绝对优势,但美国政府部门已为单原子催化剂工业化做好专利布局。高价值专利中以Pt原子与碳材料载体组成的单原子催化剂为最多。最后指出单原子极限下精确调节催化材料是单原子催化剂工业化制备面临的挑战。

Abstract:

Single-atom catalysts with unique physical and chemical properties are superior to traditional catalysts for some chemical reactions and thus will become the next generation catalysts. Single-atom catalysts technology has made great progress. Here, the origin of single-atom catalyst was traced back, and bibliometrics and patent statistics methods were used to analyze the related papers and patents in the field of single-atom catalysts from multi-dimensional indicators. The results show that both the basic theory and application research of single-atom are catalysts in the rising stage, and China is in the international leading position. In basic research, Chinese Academy of Sciences, Tsinghua University and the U.S. Department of Energy have demonstrated super strength. In application research, although China has the most patent applications, the patent layout in single-atom industrialization was best done by the U.S. governments. The most valuable patents for single-atom catalysts are those composed of active center of Pt atoms and carbon materials. Finally, the challenge to achieve real industrial applications of single-atom catalysis is pointed out to be the precise regulation of the catalytic materials within their single-atom limit.

Key words: single-atom, catalysis, support, industrialize, preparation
