“…However, these materials have limitations; for example, TiO 2 works only under UV light due to its 3.0–3.2 eV band gap, 21 while metal sulphides are unstable due to photocorrosion. 22 Graphitic carbon nitride (g-C 3 N 4 ) has garnered significant attention due to its appealing characteristics, which include a moderate band gap, high thermal stability and a large surface area. 23,24 Graphitic carbon nitride photocatalysts can work efficiently under sunlight.…”

The development of efficient and stable photoanode materials is essential for driving the possible practical application of photoelectrochemical water splitting. This article begins with a basic understanding of the fundamentals of photoelectrochemical devices and photoanodes. State‐of‐the‐art strategies for designing photoanodes with long‐term stability are highlighted, including insertion of hole transport layers, construction of protective/passivation layers, loading of co‐catalysts, construction of heterojunctions, and modification of the electrolyte. Based on the insights gained from these effective strategies, we present an outlook for addressing key aspects of the challenges of stabilizing photoanodes development in the future work. Widespread adoption of stability assessment criteria will facilitate reliable comparisons of results from different laboratories. In addition, deactivation of photoanode is defined as a 50% reduction in productivity. An in‐depth understanding of the deactivation mechanism is essential for the design and development of efficient and stable photoanodes. This work will provide insights into the stability assessment of photoanode and facilitate the production of practical solar fuels.
