In this review, we summarize recent advances in the design and development of electrocatalysts for the N2 reduction reaction. We also discuss the strategies to boost catalytic performances, the methods for reliable NRR experiments, and perspectives for further research directions.
Conductive metal–organic frameworks (MOFs) have been studied extensively in applications like water electrolysis, gas storage, and supercapacitors due to their high conductivity and large pore volume. In this communication, we report the first use of a conductive Ni-MOF as a non-noble-metal catalyst for efficient electro-oxidation of glucose in alkaline electrolyte. As an electrochemical sensor for glucose detection, this Ni-MOF shows a fast response time of less than 3 s, a low detection limit of 0.66 μM (S/N = 3), and a high sensitivity of 21 744 μA mM−1 cm−2. This glucose sensor also displays excellent selectivity, stability and reproducibility, and its application for the detection of glucose in real samples is also demonstrated successfully.
Supercapacitors (SCs) are promising for bridging the power/energy gap between conventional capacitors and batteries/fuel cells. However, challenges remain in the improvement of electrode materials toward high capacitive performance. Electrospun nanofibers, prepared via facile and low-cost electrospinning techniques, exhibit superior electrochemical performance in SCs due to their unique morphology and intriguing properties, demonstrating great potential for improving the performance of SCs. Herein, we review the recent progress in electrospun one-dimensional nanofibers as electrode materials for SCs. Three categories of electrospun electrode nanomaterials (i.e., carbon nanofibers, carbon nanofiber composites, and carbon-free transition metal oxides) are discussed with design and optimization strategies. Moreover, critical insights into the electronic conductivity, electrochemical response and durability of electrospun nanofibers are reviewed. Finally, we conclude with an outlook on how these discussions and insights open opportunities for electrospun nanofibers (as electrode materials) to expand their potential application in next-generation SCs.
