学位论文视角下的中国氢能研究现状

Analysis on research status of hydrogen energy in China from perspective of dissertations

在对我国氢能研究现状进行深入调研和分析的基础上,采用文献计量和科学知识图谱相结合的方法对我国近10年来(2013—2022年)氢能主题的硕士、博士学位论文进行系统性的梳理与总结。研究发现,我国现处于氢能研究的高速发展时期,相关学位论文数呈快速上升趋势;绝大部分学位论文属于技术研发及应用层次,所涉及学科种类较多但主要集中于化工和材料2大类;高频关键词都围绕制储氢、催化剂及其相关技术展开;经过10余年的政策布局,我国现已形成较为完备的政策体系。建议继续加大基础研究力度和技术创新力度,加强我国氢能产业创新体系建设和产学研合作,开展示范运行及推广工作,促进中国氢能产业的可持续发展。

On the basis of in-depth investigation and analysis on the current situation of hydrogen energy research in China,this paper systematically sorts out and summarizes the master's and doctoral dissertations on the theme of hydrogen energy in China in the past ten years(2013—2022)by combining bibliometrics and scientific knowledge mapping.The development process and current situation of hydrogen energy research in China are comprehensively demonstrated from the aspects of the annual number of public dissertations,disciplines,level of publication,degree awarding units and research hotspots.Finally,the development process of China's hydrogen energy policy is analyzed and some suggestions are put forward for addressing the existing problems.It is found that China is now in a period of rapid development of hydrogen energy research,and the number of related dissertations is rising rapidly.Most of the dissertations belong to the level of technology research and application,involving many disciplines but mainly focusing on chemical engineering and materials.High-frequency key words are centered on hydrogen production and storage,catalysts and related technologies.After more than ten years of policy layout,China has formed a relatively complete policy system.It is suggested to continue to strengthen basic research and technological innovation,strengthen the construction of China's hydrogen energy industry innovation system and industry-university-research cooperation,carry out demonstration operation and promotion work,and promote the sustainable development of China's hydrogen energy industry.
