摘要
氢能是一种清洁、高效、安全、可持续的新能源,具有较高的能量密度和可再生性,被认为是最具应用前景的能源之一,各国已将氢能的开发与利用纳入国家能源战略布局中。氢的制备技术是开发利用氢能的关键性技术之一,如何制备清洁的"绿氢",是该项技术研究的焦点。该文以科学引文索引扩展数据库(SCIE)和智慧芽(PatSnap)专利数据库为数据源,采用文献计量和专利分析相结合的方法,从年代、国家、机构、主题等角度,分析近10年全球绿色制氢技术在基础研究及技术研发方面的发展态势。结果显示:2010年以后,绿色制氢技术领域无论是发文量还是专利申请量一直保持增长趋势,专利公开授权量也大幅增长。中国是绿色制氢技术领域主要的研究国家,但论文综合影响力不如美国。除中国以外,美国、日本、德国和韩国在绿色制氢方面从基础研究到产品应用也均有所涉及。从研究机构上看,绿色制氢技术领域的论文多由高校或研究机构完成,而专利的申请主体主要是公司。光电催化分解水制氢以及石墨/石墨烯电极制备是当前基础研究的热点也是技术研发的焦点,未来在二氧化钛电极、燃料电池制备的研究和开发值得关注。
Hydrogen energy is a clean, efficient, safe and sustainable new energy source. With high energy density and reproducibility, it is regarded as one of the most promising energy sources. Countries have incorporated the development and utilization of hydrogen energy into the national energy strategic layout. Hydrogen production technology is one of the key technologies to develop and utilize hydrogen energy. How to prepare clean "green hydrogen" is the focus of this technology research. Using science Citation Index Extension Database(SCIE) and PatSnap patent database as the main data sources, adopting the method of combining bibliometric analysis and patent analysis to analyze the global development trends of hydrogen production technology in basic research and technology R&D in recent ten years from the perspective of years, countries, institutions and topics. The results show: after 2012, both the number of publications and patent applications in the field of green hydrogen production technology have maintained a growing trend, and the number of patent grants has also increased significantly. China is the major research country in the field of green hydrogen production technology, but its comprehensive influence is not as great as that of the United States. In addition to China, the United States, Japan, Germany and South Korea are also involved in green hydrogen production, from basic research to product applications. From the perspective of research institutions, papers in the field of green hydrogen production technology are mostly completed by universities or research institutions, while the main body of patent application is the company. Photocatalytic decomposition of water to produce hydrogen and preparation of graphite/graphene electrode are the focus of basic research and technical development at present. In the future, the research and development of titanium dioxide electrode and fuel cell preparation are worthy of attention.
