Specifically, constructions of the novel electrochemical interface using various nanomaterials and exploring their advanced electrochemical properties have received great attention to develop electrochemical devices with potential applications. In this account, we focus on our up-to-date progress in the construction of novel electrochemical interfaces based on nanomaterials, mainly highlighting our research advances on electrochemical sensors, fuel cells and fluorescence spectroelectrochemistry. These novel advanced nanomaterials endow them excellent performances and open the door towards the development of new generation of electrochemical nanodevices. The introduction of them is beneficial to accelerating electron transfer and improving their electrocatalytic efficiency in the field of electrochemical sensors and fuel cells. Searching for and synthesizing proper luminescence materials and electrochromic species with excellent spectrum matching were designed to fabricate novel electroswitching fluorescence nanodevices. In addition, the optimization of the fabrication for multiple stimuli-responsive systems and the realization of their multifunctions were further explored. Finally, future challenges and perspectives toward these research fields mentioned above are described.
