TiO2 nanospheres were synthesized and then modified with copper(II) sulfide (CuS) to form TiO2-CuS-a and TiO2-CuS-b, respectively, by two different loading methods (direct deposition vs bifunctional linker coupling). The structural, morphological, and optical properties of the two different composites TiO2-CuS-a and TiO2-CuS-b were characterized and compared using FESEM, HRTEM, XRD, XPS, BET, and DRS techniques. The TiO2CuS-b with a regular spiky-ball-like structure exhibited enhanced disinfection ability, improved photodegradation performance of organic pollutants, and hydrogen evolution efficiency under solar and UV light as compared to TiO2-CuS-a (direct deposition method) due to its higher effective combination with CuS through the bifunctional linking molecule, L-cysteine. The influence of CuS content, the structure, and the charge transfer mechanism were systematically investigated by PL, CV, EIS, and EPR techniques.
