旨在揭示燃料乙醇作为一种生物环境友好的可再生资源,其研究领域内的热点和前沿。借助CiteSpace软件,对燃料乙醇研究领域的ESI高被引论文,从数量特征和内容特征进行分析,构建基于全球研究视野的燃料乙醇研究图谱。经分析发现燃料乙醇最受关注的5个研究热点分别为乙醇和其他燃料混合对发动机性能的影响、直接碱性乙醇燃料电池、利用农业残留物制备燃料乙醇、木质纤维素的预处理工艺及无金属电催化剂研发方向;前沿演化趋势为燃料乙醇在其生命周期内产生的环境排放——乙醇柴油混合燃料对发动机动力性、经济性和排放特性的影响——以醇类为燃料的燃料电池的电催化剂研究。美国燃料乙醇的研究在全球具有引领作用,中国高被引论文质量有待提高。
The hotspots and frontiers of fuel ethanol research as a bioenvironmentally friendly renewable resource were revealed.With the help of CiteSpace software,ESI highly cited papers in the field of fuel ethanol research were analyzed from quantitative characteristics and content characteristics,and constructed a fuel ethanol research map based on a global research perspective.Five research hotspots of fuel ethanol were found:the influence of ethanol and other fuels on engine performance,direct basic ethanol fuel cell,preparation of fuel ethanol from agricultural residues,pretreatment process of lignocellulose,and research direction of metal-free electrocatalyst.Frontier evolution trends:environmental emissions of fuel ethanol during its life cycle——effects of ethanol and diesel blends on engine power,economy,and emission characteristics——studies on electro-catalysts for alcohol-based fuel cells.The research on fuel ethanol in the United States played a leading role in the world,while the quality of highly cited papers in China needed to be improved.
