This review paper summarizes how combining metal oxide semiconductors with g-C₃N₄, a stable and low-cost 2D material, has led to a new generation of chemiresistive gas sensors with higher sensitivity, better selectivity, and in many cases operation at lower temperatures. By explaining how g-C₃N₄ provides abundant active surface sites and improves charge transfer through heterojunction formation, the paper shows why these nanocomposites outperform traditional metal oxide sensors. It highlights the scientific progress made in designing ZnO/g-C₃N₄, SnO₂/g-C₃N₄, Co₃O₄/g-C₃N₄, and other hybrid structures, connecting synthesis methods with improved sensing behavior for gases such as NO₂, acetone, ethanol, CO, and toluene.
