Abstract In situ grown copper (Cu) metal is commonly integrated with Cu 2 O to enhance charge separation and improve photocatalytic degradation of azo dyes, such as Orange II Methyl orange (MO). However, limited solvent diffusion remains a critical challenge for effective pollutant removal. Inspired by the dandelion structure, this work synthesizes Cu/Cu composite an interconnected nanotube structure hollow nanosphere, facilitating transport increasing active surface area. The optimized O‐S3 catalyst achieves 93 % photodegradation efficiency maintains 98 stability over five cycles at concentration 100 mgL −1 , significantly outperforming MO. While previous studies have attributed performance dihedral angle planarity II, role photogenerated electron catalyst‐dye interface largely overlooked. Here, reveals that transfer from 3 d orbitals p energy levels N, C, atoms, enhancing carrier mobility binding interactions. Moreover, extra α‐OH group in promotes uniform electronic distribution planar π‐bond formation, further improving performance. These insights provide deeper understanding mechanisms offer valuable strategies designing more efficient catalysts.
