Semiconductor-based photocatalytic and photoelectrochemical water splitting is an ultimate source of hydrogen generation for tackling the ongoing fuel crisis. In this context, we have synthesized a highly porous N-rich g-C3N4 metal-free, nontoxic semiconductor through polycondensation method. present work, discussed major changes in morphology after acidic exfoliation thoroughly by using transmission electron microscopy (TEM) scanning (SEM) studies. The chemical purity as-synthesized materials was analyzed powder X-ray diffraction (PXRD). specific surface area porosity were obtained Brunner–Emmet–Teller (BET) Besides this, electronic structure absorption near-edge spectroscopy (XANES), elemental composition determined photoelectron (XPS). Moreover, dependency sacrificial agents detail sodium sulfide/sodium sulfite (Na2S/Na2SO3) triethanolamine (TEOA). It observed that exfoliated shows remarkable evolution presence TEOA efficient quantum yield up to 12%, which 1.7-fold higher than Na2S/Na2SO3 (7%). Furthermore, harness most solar light spectrum, high current density improved Faradaic efficiency during photoelectrocatalysis been reported.

Hydrogen energy is environmental-friendly and considered an attractive alternative to fossil fuels. Among the feasible technologies for hydrogen generation, photocatalysis-derived from water splitting be optimal solution meeting long-term sustainability increased demands. In this context, various photocatalytic genres are proposed, with metal carbon-supported photocatalysts demonstrating greater comprehensiveness potential addressing solar-driven production water. Several important aspects of aforementioned reviewed in present work effort provide pertinent researchers new horizons more advanced performance. The review initiated by introducing primary principles photocatalysis, as well prerequisites generation focus then moves metal-based photocatalysts, where features these materials summarized. Related limitations also discussed, along proposed strategies that could potentially mitigate them. Similar systematic summaries made knowledge on carbon-based photocatalysts. concludes a discussion future research directions light bottlenecks currently encountered. With proper development, produce clean water, thereby fueling global development without causing environmental harm.
