Porphyrin derivatives have been extensively explored as photocatalysts for PHE, owing to their efficient light-harvesting ability in the UV–Vis absorption region, stable photoexcited states, reversible redox properties, high photo and chemical stabilities, and tailorable optoelectronic properties via structural engineering. However, the monomeric porphyrin photocatalysts typically exhibit a narrow absorption range in the visible spectrum, susceptibility to light corrosion, and difficulty in loading cocatalysts such as Pt due to limited interface contact area. These issues lead to a low electron transfer efficiency between monomeric porphyrin photocatalyst and cocatalyst and thus inferior PHE performance. In addition, porphyrin photocatalysts in their bulk powder form usually possess uncontrolled morphologies and thus inefficient separation and migration of photoinduced charge carriers, which subsequently lowers the PHE performance. To address these challenges, the development of self-assembled porphyrin derivatives with well-defined sizes and shapes in the solid state presents a promising strategy. Over the past decade, significant advancements have been made in creating porphyrin-based self-assembled materials for efficient PHE. In this review, we summarize the progress in developing porphyrin-based self-assembled materials for PHE, highlighting how the morphology of self-assembled porphyrins affects their light-harvesting abilities, electronic properties, and separation and migration of photoinduced charge carriers, ultimately impacting their PHE performances.

Hydrothermal treatment is a low-carbon technology for the valorization of lignocellulosic biomass toward diverse value-added bioproducts through the disintegration and conversion of lignocellulosic biomasses. This review first introduces the chemical compositions of lignocellulosic biomasses and the operating principles of hydrothermal treatment. Then, the transformation of the chemical compositions during hydrothermal treatment (&lt;300 °C) is elucidated comprehensively. In addition, the recent advances in the hydrothermal valorization of lignocellulosic biomass into bio-oil, wood vinegar, briquette fuels, absorbents, carbonaceous electrode materials, and catalysts are introduced and discussed emphatically. The bridge between the hydrothermal treatment and the physicochemical properties and performances of the obtained value-added bioproducts is further built. The precise removal of chemical compositions and the followed directional conversion are the keys affecting the structure and physiochemical properties of the bioproducts. It is difficult to regulate the extraction and decomposition of chemical compositions in one step because of the heterogeneous structure and recalcitrant cross-linking barrier of lignocellulosic biomass. In this regard, a multi-step process is promising undoubtedly, while tailoring the specific application is necessary for industrialization due to the diversity of bioproducts. The future direction of fully efficient utilization of lignocellulosic biomass is proposed for the researches on the multipurpose valorization of high-value-added bioproducts.
