In order to enhance the photocatalytic performance of the Cu 2 ZnSnS 4 compound, an ionic substitution strategy was employed to partially and completely substitute Zn 2+ with Cr 3+ ions using the solvothermal method. The structural analysis reveals that partial substitution significantly improves the crystallite lattice order without disturbing the kesterite crystal structure, confirming the successful incorporation of chromium into the lattice. Morphological investigations imply the formation of spherically aggregated nanorods-like, which efficiently arise the lively surface area, at the same time as EDS analysis confirms a homogeneous elemental distribution without the formation of secondary phases. Upon comparing the photocatalytic performance of all synthesized compounds using methylene blue dye as a version pollutant, the Cu 2 Zn 0.5 Cr 0.5 SnS 4 compound showed the highest degradation efficiency of about 93% within 120 min in visible light irradiation. This more desirable overall performance is attributed to the synergistic outcomes of advanced crystallinity, changed morphology, and enhanced light absorption caused by partial Cr3 substitution. These consequences exhibit that managed ionic substitution represents an effective approach for tailoring the structural and photocatalytic residences of the Cu 2 ZnSnS 4 compound-primarily based substances for environmental remediation packages.
