“…For example, the formation of heterojunctions by encapsulating semiconductor particles into porous materials can enhance interfacial contact, which further improves the electron−hole separation rate. Qin et al 103 have investigated the PC heterojunction, Ag 2 O/Fe-MOF, to convert various MPs such as polyethylene glycol (PEG), PE, and PET into small hydrocarbon molecules and to generate H 2 . The electron− hole separation efficiency of Ag 2 O/Fe MOF, measured by photocurrent density, is higher than that of Ag 2 O and Fe-MOF, which can be ascribed to the efficient integration between Ag 2 O and Fe-MOF, forming a p-n heterojunction structure thus promoting electron−hole separation.…”

Photoreforming (PR) technology is a green and sustainable approach to tackling the environmental pollution problems generated by plastic waste. In this review, recent advances in the PR of plastic waste are summarized that include the design of photocatalysts, regulations on the products, and innovations on the PR devices and compared to traditional methods. The scientific principles of PR reactions in thermodynamics and kinetics are discussed, and approaches to improve the efficiency of PR reactions are proposed, that involve enhancement in light absorption ability, charge carrier migration/separation efficiency, and surface reaction rate. Particularly, the enhancement for H2 production in the PR reaction is highlighted, and the applications using large-scale reactors are discussed, with advantages and disadvantages of recent reactor configurations. In conclusion, the perspectives on the applications of PR in plastic degradation and hydrogen evolution are given. This review thus comprehensively summarizes scientific principles, challenges, and perspectives of PR reactions on plastic waste to improve the overall efficiency and potential to be applied in the industry.

“…[ 133 ] Another way is photochemical synthesis, in which metal oxide semiconductor nanoparticles are synthesized inside porous MOFs. [ 134 ] Strong contacts between these MOFs and microplastics via hydrogen bonds, Van der Waals interactions, and electrostatic interactions make it easier to get the right contact for facile removal, which is a significant problem with pure transition metal oxides. Another component that favors interaction with the microplastic and quick solvent flow is the correct pore configuration of the MOFs.…”

The ubiquitous presence of microplastics in the environment has raised serious environmental and health concerns. These tiny plastic particles can enter the food chain, posing a significant threat to human health. Researchers worldwide have focused their efforts on developing strategies to mitigate microplastic pollution. This review focuses on the potential of nano/microstructured metal oxide semiconductors as effective photocatalysts for microplastic degradation. The review is divided into two sections: static metal oxides and dynamic micromachines based on metal oxides. The modifications made to nano/microstructured metal oxides such as TiO2, ZnO, bismuth oxyhalides (BiOX), NiO, Cu2O/CuO, perovskite‐like Bi2WO6, Fe3O4, etc., to enhance their degradation efficiency are thoroughly discussed and reviewed. Additionally, the photocatalytic pathways for the conversion of microplastics into C2 fuel and other value‐added products are also elaborated. The current developments in the realm of dynamic, self‐propelled, and controlled micromotors for the photodegradation of microplastics are also highlighted. The review concludes by proposing future perspectives and challenges to facilitate the remediation of microplastics in water and wastewater systems in a more effective, scalable, and environmentally friendly manner. Overall, the review emphasizes the potential of photocatalysis using nano/microstructured metal oxide semiconductors as an eco‐friendly and promising approach for microplastic degradation.

Metal–organic frameworks (MOFs) have emerged as ideal multifunctional platforms for renewable hydrogen (H2) energy applications owing to their tunable chemical compositions and structures and high porosity. Their advanced component species and porous structure contribute greatly to the enhanced activity, electrical conductivity, photo response, charge‐hole separation efficiency, and structural stability of MOF materials, which are promising for practical H2 economy. In this review, we mainly introduce design strategies for the enhancement of electro‐/photochemical behaviors or adsorption performance of porous MOF materials for H2 production, storage, and utilization from compositional perspective. Following these engineering strategies, the correlation between composition and property‐structure‐performance of pristine MOFs and their composite with advanced components is illustrated. Finally, challenges and directions of future development of related MOFs and MOF composites for H2 economy are provided.
