The simple and cost-effective method was adopted to prepare hollow 1D porous structure of g-C3N4 to generate hydrogen by photocatalysis. It plays a substantial role in efficient photocatalysis of water splitting. In general, the protonated melamine was calcined at high temperature to get 1D structure. It exhibits improvement in hydrogen evolution (2.54 mmol. g -1 .h-1 ) in contrast to bulk g-C3N4 (0.10 mmol. g-1 .h-1 ). Due to porous in nature, it has a high surface area (51.369 m2 g -1 ) in contrast to bulk sample (7.73 m2 g -1 ). Furthermore, 1D structure display low resistance against the charge transfer and have low recombination rate. These observations claiming that the hollow 1D porous structure play a crucial role to enhance photocatalytic activity.
