To overcome this, the modification process of g-C<small>₃</small>N<small>₄</small> was designed through a molten salt method to achieve a nanorod morphology and introduce N defects (CN-PS, CN-PC, and CN-SS). During the process, the alkali metal salt not only promoted the introduction of N1 vacancies at a low synthesis temperature as a solid solvent and introduced an additional cyano group (–C<img>N) into the CN-SS but also acted as a morphology guide agent to transform the modified catalyst into a nanorod morphology. The nanorod morphology provided a one-dimensional pathway for charge migration, and the N defect enhanced the photocatalytic activity while regulating the band structure. The morphological control and defect engineering endowed modified catalysts with enhanced hydrogen evolution performance.
