Abstract
Solar-driven photocatalysts for water splitting and CO 2 reduction have been widely studied for dealing with environmental pollution and energy sustainability issues. Among the most promising semiconductor photocatalysts, graphitic carbon nitride (g-C 3 N 4 ) and TiO 2 (anatase) with band gaps of ∼2.7 and ∼3.2 eV, respectively, are investigated extensively. However, the high photogenerated carrier recombination efficiency of g-C 3 N 4 and the relatively wide band gap of TiO 2 (responsive to ultraviolet light only) are the factors that can lower the photocatalytic activities of the materials. Thus, one of the prevalent strategies is to construct g-C 3 N 4 /TiO 2 nanocomposites to promote charge carrier separation and to improve photoabsorption in the visible region for attaining efficient utilization of solar energy in photocatalytic water splitting, CO 2 reduction, and organic pollutant photodegradation. Here, a comprehensive overview is made on the exploitation of g-C 3 N 4 /TiO 2 nanocomposites for photocatalytic applications, emphasizing layered heterostructures, for solar-driven H 2 generation and CO 2 reduction. Challenges in resolving various issues such as low efficiency, low stability, and noble metal cocatalyst dependency, as well as band gap narrowing accompanied reduction in redox ability of the g-C 3 N 4 /TiO 2 nanocomposites, are discussed. • Layered g-C 3 N 4 /TiO 2 nanocomposites for photocatalytic water splitting and CO 2 reduction are reviewed. • g-C 3 N 4 /TiO 2 heterostructure-based catalysts with various dimensions are extensively explored. • Kinetics and mechanism of photocatalysis of g-C 3 N 4 /TiO 2 nanocomposites are described. • Challenging issues associated with high efficiency and durability of the system are discussed.
