Abstract Addressing global energy and environmental challenges requires innovative advancements in sustainable technologies. Photocatalytic hydrogen evolution (PHE) is a promising approach for clean production through the efficient conversion of solar into hydrogen. Despite ongoing challenges, improving structural design photo/electrochemical properties graphitic carbon nitride (g‐C₃N₄) remains essential boosting efficiency PHE, contributing to solutions crisis pollution. Herein, we present novel 3D hierarchical porous g‐C₃N₄ nanocoral structure doped with sulfur oxygen (3D SO‐CN1), synthesized via simple hydrothermal followed by calcination. The unique architecture significantly increases surface area, providing abundant active sites while promoting light absorption charge carrier separation compared pristine g‐C 3 N 4 . As result, SO‐CN1 catalyst loaded wt% Pt exhibits an impressive rate 27.38 mmol⋅g⁻¹⋅h⁻¹ under visible‐light irradiation, using 15 vol% triethanolamine (TEOA) as sacrificial agent. Notably, proposed 51‐fold enhancement g‐C₃N₄. Additionally, it notable apparent quantum (AQE) 5.26% at 420 nm, highlighting its superior photocatalytic performance. This study underscores synergy dual heteroatom doping morphological engineering optimizing next‐generation production.
