Designing Hierarchical Porous Amorphous MoC x Nanoflowers for Efficient Electrocatalysis
Source abstract
Abstract
Transition metal carbides (TMCs) have emerged as highly promising candidates for catalytic applications. However, achieving synergistic modulation of their crystalline phase and hierarchical pore structure─a critical factor for stabilizing active sites and enhancing catalytic activity─remains a formidable challenge. Herein, we develop a self-sacrificial template strategy for synthesizing nanoflower-like amorphous molybdenum carbide (NF a-MoC x ) with a controlled architecture. This approach enables the creation of a hierarchical micro/mesoporous structure that enlarges the surface area while establishing a favorable reaction microenvironment for efficient mass transport. As a proof of concept, the amorphous structure of NF a-MoC x serves as an ideal support to achieve effective regulation of the particle size and uniform dispersion of Pt nanoparticles (2 nm), resulting in a power density of 117.67 mW cm –2 in Zn–air energy devices.
