Abstract Quantum dots (QDs), with adjustable bandgaps, high interfacial reactivity, and efficient charge transfer, are promising in photocatalytic bacteriostasis. However, challenges like fast recombination, instability, aggregation limit their catalytic efficiency broader applications. A dual‐carrier system of regenerated cationic cellulose (RCC) Ga is first proposed to achieve steady‐state Cu x S QDs quantum confinement, sulfur‐rich vacancies, p‐type Schottky structure, maximizing activity. The junction interface internal electric field accelerate carrier separation, while sulfur vacancies act as hot electron traps, further suppressing electron–hole recombination. Therefore, this ternary composite demonstrates an optimal bandgap (2.25 eV), low electrochemical impedance, extended photoluminescence decay (9.87 ns), broad‐spectrum light absorption, thereby improving conversion into ROS, including 1 O 2 . These reactive species high‐efficiently sterilize E. coli , S. aureus drag‐resistant bacteria, achieving logarithmic removal values 6–8 at a bacterial concentration (10 8 CFU mL −1 ) under visible‐light illumination. Pathogen demise primarily results from photo‐excited which induce instability even substantial damage microbial membranes, leading excessive oxidative stress degradation essential cellular components, superoxide dismutase, catalase, DNA. This study introduces innovative organic/inorganic strategy for designing semiconductor QD‐based disinfection photocatalysts.
