“…[ 169 ] Lastly, the carbon and nitrogen sources in MOFs can be used as precursors to form highly photoactive materials such as g‐C 3 N 4 . [ 170 ] All of the above results demonstrate that MOFs are unique precursors for hybrid photocatalysts with porous structures for effective mass transport and rapid charge transport to suppress charge recombination.…”

Solar fuel production, water splitting, and CO2 reduction by sunlight‐assisted catalytic reactions, are attractive and environmentally sustainable approaches used to generate energy. Since many different parameters, including energy band structures, electronic conductivity, surface area, porosity, catalytic activity, and stability of photocatalytic materials, determine the photocatalytic reaction, a single photocatalytic material is often insufficient to fulfill all the requirements. Hybridization to complement the limitations of two or more component materials can provide a viable solution. Particularly, hybridization with metal organic frameworks (MOFs), a new class of materials with excellent controllability of topology, surface area, porosity, morphology, band structure, electrical conductivity, and composition, enables the on‐demand design of a myriad of high‐performance photocatalysts. Moreover, hybrids formed by MOF‐derived materials inherit the distinctive merits from the MOF and offer further diversification for hybrid photocatalysts. Here, the rational design of MOF‐based hybrid photocatalysts for solar fuel production is discussed. The synthetic strategies of diverse MOF‐based hybrids, the key physicochemical parameters of hybrids to determine photocatalytic and photoelectrochemical reactions, and the mechanisms underlying the synergistic enhancement of solar fuel production are reviewed. Moreover, remaining challenges and future perspectives are addressed.

“…In addition, various existing researches have proven that implanting the anion–cation into the g-C 3 N 4 frameworks could regulate their bandgap structure for broader visible-light absorption, facilitate the bulk phase and interface charge separation and lead to enhanced photocatalytic activity for H 2 evolution [ 21 , 22 , 23 ]. For instance, Qiao et al [ 24 ] found that a new intermediate energy level was formed in the bandgap of g-C 3 N 4 via the insertion of P into its skeleton, which received the electrons generated by light excitation from VB and thus improved the separation of photocarriers.…”

Graphitic C3N4-based materials are promising for photocatalytic H2 evolution applications, but they still suffer from low photocatalytic activity due to the insufficient light absorption, unfavorable structure and fast recombination of photogenerated charge. Herein, a novel anion–cation co-doped g-C3N4 porous nanotube is successfully synthesized using a self-assembly impregnation-assisted polymerization method. Ni ions on the surface of the self-assembly nanorod precursor can not only cooperate with H3P gas from the thermal cracking of NaH2PO2 as an anion–cation co-doping source, but, more importantly, suppress the shape-collapsing effect of the etching of H3P gas due to the strong coordinate bonding of Ni-P, which leads to a Ni and P co-doped g-C3N4 porous nanotube (PNCNT). Ni and P co-doping can build a new intermediate state near the conduction band in the bandgap of the PNCNT, and the porous nanotube structure gives it a higher BET surface area and light reflection path, showing a synergistic ability to broaden the visible-light absorption, facilitate photogenerated charge separation and the light-electron excitation rate of g-C3N4 and provide more reaction sites for photocatalytic H2 evolution reaction. Therefore, as expected, the PNCNT exhibits an excellent photocatalytic H2 evolution rate of 240.91 μmol·g−1·h−1, which is 30.5, 3.8 and 27.8 times as that of the pure g-C3N4 nanotube (CNT), single Ni-doped g-C3N4 nanotube (NCNT) and single P-doped g-C3N4 nanotube (PCNT), respectively. Moreover, the PNCNT shows good stability and long-term photocatalytic H2 production activity, which makes it a promising candidate for practical applications.
