Nanomaterial selection is critical for photoelectrochemical (PEC) sensing. In this report, a novel cathodic photoelectrochemical (PEC) strategy was proposed for the detection of doxorubicin hydrochloride (Dox) and gentamicin sulfate (CN). The photocathode was synthesized by noncovalently coupling cadmium sulfide (CdS) to the porphyrin-derived metal–organic framework (CdS@PCN-224). This type of assembly created a pleasant interface for the combination of doxorubicin hydrochloride and gentamicin sulfate, resulting in a good CdS@PCN-224 donor–acceptor system. When compared to a single optoelectronic material, its photocurrent is enhanced by unprecedented nine times. This research could pave the way for the realization of PCN-224’s enormous potential in PEC sensing.
