“…Nowadays, with the constant exploitation of the nonrenewable fossil fuels, the crisis of energy shortage is inevitable. [ 1–6 ] In addition, the burning of fossil fuels has caused severe environmental issues in recent years, which threatens the health of humanins. Under such circumstances, exploring sustainable energy resources to replace conventional fossil fuels has attracted much attention of researchers worldwide.…”

Photocatalytic H2 evolution is regarded as an ideal approach to produce green energy. Here, a step‐scheme (S‐scheme) heterojunction of macro/mesoporous TiO2/g‐C3N4 photocatalysts with enhanced H2 evolution performance is constructed via a simple chemical vapor deposition process. It is found that the microstructure of samples can be easily controlled by adjusting the dosage of melamine. As compared to the respective monocomponent TiO2 and g‐C3N4, the H2 evolution rate of TiO2/g‐C3N4 S‐scheme heterojunction is greatly improved. The H2 evolution rate of the 20CT sample reaches the maximum value of 3211 μmol g−1 h−1, which is much higher than those of TiO2 and g‐C3N4 by factors of 27.2 and 7.5, respectively. In addition, through in‐depth analysis with photoluminescence, X‐ray photoelectron spectroscopy, and Mott–Schottky characterizations, a new mechanism of S‐scheme heterojunction is proposed for the obtained system. The formation of the S‐scheme heterojunction in TiO2/g‐C3N4 is therefore responsible for the observed photocatalytic performance enhancement, due to the efficient charge separation as well as the high redox ability.

“…Since Fujishima and Honda reported photoelectric decomposition of water on TiO 2 cells in 1972, [4] photocatalytic production of hydrogen has become a hot spot. In the past decades, photocatalysis has been regarded as one of radical and environmentally friendly solutions to global environmental and energy problems [5–8] Since the efficiency of photocatalysis is heavily dependent on the employed photocatalysts, the design and development of highly efficient photocatalysts are of paramount significance. For satisfactory photocatalytic efficiency, researchers are devoted to developing visible light responsive semiconductors, such as g‐C 3 N 4 , [9] BrOX, [10] CdS [11] and ZnIn 2 S 4 [12] …”

Pt is usually used as cocatalyst for g-C 3 N 4 to produce H 2 by photocatalytic splitting of water. However, the photocatalytic performance is still limited by the fast recombination of photo-generated electrons and holes, as well as the poor absorption of visible light. In this work, MoO 2 /g-C 3 N 4 composites were prepared, in which MoO 2 synergetic with Pt photo-deposited during H 2 evolution reaction worked as unilateral dual cocatalyst to improve the photocatalytic activity. Within 4 hours of irradiation, the hydrogen production rate of MoO 2 -Pt dual cocatalyst modified g-C 3 N 4 reached 3804.89 μmol/g/h, which was 120.18 times of that of pure g-C 3 N 4 (GCN, 31.66 μmol/g/h), 10.98 times of that of MoO 2 modified g-C 3 N 4 (346.39 μmol/g/ h), and 9.18 times of that of Pt modified g-C 3 N 4 (413.64 μmol/ g/h). Characterization results demonstrate that the deficient MoO 2 not only promoted visible light absorption of g-C 3 N 4 , but also worked as a "electron pool" to capture and transfer electrons to Pt.
