Coordination-driven self-assembly of MOF-based heterostructures for electrocatalytic methanol oxidation
Journal of Solid State Chemistry(2023)
摘要
Direct methanol fuel cells (DMFCs) are considered one of the most promising energy conversion devices due to their environmentally friendly and high-energy density features. However, the sluggish anode kinetics of the methanol oxidation reaction (MOR) acts as a bottleneck in the DMFCs system. Herein, a series of MOF-based heterogeneous electrocatalysts (NiWO4/MOF-74-x, Ni3V2O8/MOF-74-x) is constructed via a coordination-driven self-assembly strategy to enhance the catalytic property of the MOR. The heterogeneous interface between MOF-74 and Ni compounds is built by the Ni–O coordination interaction, which provides fast charge transfer and mass diffusion efficiency. Therefore, the optimal catalyst NiWO4/MOF-74 (3) exhibits excellent MOR activity and operation durability with a peak current density of 28.58 mA·cm-2. This work is expected to inspire the design of more efficient MOF-based heterogeneous electrocatalysts for MOR and other energy conversion applications.
