“…Other tunable properties related to their structure are light absorption, lifetime of the excited singlet state, stability, aggregation bias and regeneration ability after photooxidation, enabling a complete control of the performance through porphyrin engineering [ 26 ]. For all these attributes, these structures are considered powerful candidates for photosensitization, and their performance has recently been proved in the context of H 2 production [ 14 , 18 , 23 , 27 ], photocatalytic degradation of organic pollutants [ 23 ] and CO 2 reduction [ 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ].…”

Over the years, porphyrins have arisen as exceptional photosensitizers given their ability to act as chlorophyll-mimicking dyes, thus, transferring energy from the light-collecting areas to the reaction centers, as it happens in natural photosynthesis. For this reason, porphyrin-sensitized TiO2-based nanocomposites have been widely exploited in the field of photovoltaics and photocatalysis in order to overcome the well-known limitations of these semiconductors. However, even though both areas of application share some common working principles, the development of solar cells has led the way in what is referred to the continuous improvement of these architectures, particularly regarding the molecular design of these photosynthetic pigments. Yet, those innovations have not been efficiently translated to the field of dye-sensitized photocatalysis. This review aims at filling this gap by performing an in-depth exploration of the most recent advances in the understanding of the role played by the different structural motifs of porphyrins as sensitizers in light-driven TiO2-mediated catalysis. With this goal in mind, the chemical transformations, as well as the reaction conditions under which these dyes must operate, are taken in consideration. The conclusions drawn from this comprehensive analysis offer valuable hints for the implementation of novel porphyrin–TiO2 composites, which may pave the way toward the fabrication of more efficient photocatalysts.

Constructing a novel photocatalyst to realize both pollutant oxidation and evolved CO2 reduction in one photoredox cycle can significantly reframe the role of pollutant management. Here, self‐floating poly(bismaleimide‐co‐divinylbenzene) porous microspheres (PBMs) are filled with ZnSnO3 quantum dots (ZSO QDs) to construct a polymer composite microreactor with an S‐scheme heterojunction (ZSO QDs/AP‐PBMs). This microreactor realizes efficient catalytic oxidation and degradation of antibiotic pollutants under light, and the CO2 generated in this process is reduced to high value‐added CO, allowing for the direct conversion of pollutants to a resource in one photoredox cycle. The high specific surface area of the PBMs enables the rapid and efficient adsorption of levofloxacin (LVX), and the self‐floating porous design effectively solves the problem of CO2 adsorption and mass transfer in the gas–liquid–solid three‐phase system, while the S‐scheme heterostructure enhances charge carrier separation. As a result, ZSO QDs/AP‐PBMs achieves complete degradation of LVX in one redox cycle with 100% selectivity to produce 100.3 µmol g−1 CO, and further draw a conclusion that fluoroquinones antibiotics as excellent electron donors can significantly enhance co‐catalytic effect with CO2, which is not previously reported. Theoretical calculations and characterization experiments provide information on S‐scheme heterojunction transfer mechanism and possible degradation pathways, allowing for the rational design of photoredox bifunctional catalysts.

Molecular catalysts often exhibit superior activity and selectivity in the process of photocatalytic reduction of CO2 (PCR). However, the practical application of molecular catalysts is restricted by the unsatisfied charge separation, low stability, and recycling difficulty. Fortunately, constructing organic–inorganic hybrids of molecular catalysts and semiconductors can tackle the above problems, which can improve the efficiency of charge separation and keep beneficial active sites simultaneously. However, there is no comprehensive review of the state‐of‐the‐art of the molecular catalyst/semiconductor hybrids. Herein, the present advances and challenges of the molecular catalyst/semiconductor hybrids for PCR application are outlined. Specifically, the review is summarized by the composition of semiconductors adopted to form the hybrids with molecular catalysts, including metal oxide, carbon nitride (CN), graphene, quantum dots, sulfides, layered double hydroxides (LDH), molecular complexes, and so on. The review presented here is expected to guide the design of efficient inorganic‐organic composites for solar energy conversion.
