The photocatalytic conversion of carbon dioxide (CO2) to high-value-added fuels is a meaningful strategy achieve neutrality and alleviate the energy crisis. However, low efficiency, poor selectivity, insufficient product variety greatly limit its practical applications. In this regard, conjugated organic polymeric materials including nitride (g-C3N4), covalent frameworks (COFs), triazine (CTFs) exhibit enormous potential owing their structural diversity functional tunability. Nevertheless, catalytic activities are largely suppressed by traditional amorphous or weakly crystalline structures. Therefore, constructing relevant high-crystalline ameliorate inherent drawbacks an efficient enhance performance materials. review, advantages reducing concentration defects, enhancing built-in electric field, interlayer hydrogen bonding, crystal plane regulation highlighted. Furthermore, strategies for synthesis such as molten-salt, solid salt template, microwave-assisted methods comprehensively summarized, while modification defect engineering, element doping, surface loading, heterojunction construction elaborated activities. Ultimately, challenges opportunities in CO2 prospected give some inspiration guidance researchers.
