Atomic Confinement Empowered CoZn Dual‐Single‐Atom Nanotubes for H2O2 Production in Sequential Dual‐Cathode Electro‐Fenton Process

Single-atom catalysts (SACs) are flourishing in various fields because of their 100% atomic utilization. However, their uncontrollable selectivity, poor stability and vulnerable inactivation remain critical challenges. According to theoretical predictions and experiments, a heteronuclear CoZn dual-single-atom confined in N/O-doped hollow carbon nanotube reactors (CoZn
