摘要

Two novel isomorphic Co/Ni-based metal-organic coordination polymers (MOCPs) were rationally designed and synthesized via a hydrothermal method, featuring a unique dual-ligand architecture that enabled precise control over subsequent pyrolysis products. These MOCPs served as precursors to fabricate carbon-coated polyphase metal/metal oxide composites through one-step pyrolysis, where temperature optimization was systematically investigated to balance crystallinity, carbon graphitization, and active phase formation. Comprehensive characterization revealed that Co/CoxOy@C-1000 outperformed its Ni analogue, achieving exceptional pollutant degradation efficiency due to its optimized Co0/CoxOy heterostructure and highly graphitized carbon matrix. The material demonstrated robust performance across varied conditions, excellent recyclability, and remarkable resistance to interfering anions.
