In the context of the global struggle against plastics, catalytic upgrading and recycling of plastics has been the subject of considerable attention as a powerful strategy for achieving both environmental remediation and value‐added chemical production. Compared with conventional recycling methods, the emerging photothermal catalysis methodology integrates photochemical and thermal catalytic processes, which outstands with features of high conversion efficiency and mild reaction conditions. Herein, a comprehensive review for the recent research progress of photothermal conversion of plastic waste is presented. First, the types of photothermal catalysts for plastic upcycling are classified into three categories, metallic materials, semiconductor materials, and carbon‐based materials, based on the photothermal conversion mechanism. Their potential mechanisms as powerful photothermal converters and future directions in photothermal conversion of plastics are highlighted. Furthermore, the logical structural design of photothermal catalytic materials are summarized to enhance photothermal performance in plastic conversion. Finally, future opportunities and challenges in this promising but nascent field are discussed, and future research directions for photothermal conversion of plastics are presented.

Solar steam generation (SSG) presents a promising approach to addressing the global water crisis. Central to SSG is solar photothermal conversion that requires efficient light harvesting and management. Hierarchical structures with multi‐scale light management are therefore crucial for SSG. At the molecular and sub‐nanoscale levels, materials are fine‐tuned for broadband light absorption. Advancing to the nano‐ and microscale, structures are tailored to enhance light harvesting through internal reflections, scattering, and diverse confinement effects. At the macroscopic level, light capture is optimized through rationally designed device geometries, configurations, and arrangements of solar absorber materials. While the performance of SSG relies on various factors including heat transport, physicochemical interactions at the water/air and material/water interfaces, salt dynamics, etc., efficient light capture and utilization holds a predominant role because sunlight is the sole energy source. This review focuses on the critical, yet often underestimated, role of hierarchical light harvesting/management at different dimensional scales in SSG. By correlating light management with the structure‐property relationships, the recent advances in SSG are discussed, shedding light on the current challenges and possible future trends and opportunities in this domain.

Human production and living processes emit excessive VOCs into the atmosphere, posing significant threats to both human health and the environment. The photothermal catalytic oxidation process is an organic combination of photocatalysis and thermocatalysis. Utilizing photothermal catalytic degradation of VOCs can achieve better catalytic activity at lower temperatures, resulting in more rapid and thorough degradation of these compounds. Photothermal catalysis has been increasingly applied in the treatment of atmospheric VOCs due to its many advantages. A brief introduction on the three modes of photothermal catalysis is presented. Depending on the main driving force of the reactions, they can be categorized into thermal‐assisted photocatalysis (TAPC), photo‐assisted thermal catalysis (PATC) and photo‐driven thermal catalysis (PDTC). The commonly used catalyst design methods and reactor types for photothermal catalysis are also briefly introduced. This paper then focuses on recent developments in specific applications for photothermal catalytic oxidation of different types of VOCs and their corresponding principles. Finally, the problems and challenges facing VOC degradation through this method are summarized, along with prospects for future research.
