I n recent years , research efforts have been focussed on the design and fabrication of high ly efficien t catalysts for liquid fuel cell s because the use of these cells is an important approach for alleviat ing environment al pollution and energy cris e s . However, the limit ations of the catalytic performance of the industrial Pt/C have strongly hindered the development of these fuel cells. The catalyst morphology has a strong impact on its performance; nanostructured catalysts are preferred as they offer large specific surface area and more exposed active centres. In view of this, many catalysts with unique structures have been synthesized in recent years, all of which show excellent catalytic performance characteristics . Despite these achievements, few efforts have been made to comprehensively survey this field. Herein, we summarize the recent advance s in the catalysts for liquid fuel cells , mainly focus ing on noble metal catalysts with unique morpholog ies , such as nanowires, nanosheets , and assembly structure s . Their formation mechanisms are discussed critically. We also seek to elucidate the relationship between the unique morpholog ies and excellent performance of these catalysts . We hope our work will provide guidelines for the further development of liquid fuel cells.
