Combining these motifs yields porphyrin-based COFs that couple ordered porosity with light-harvesting and metal-anchoring capabilities, offering promise for carbon dioxide capture and conversion. This review provides an integrated overview of their design, synthesis, structure, and function in the context of CO2 capture, storage, and photocatalytic\/electrocatalytic reduction. We survey recent literature, organize materials by linkage chemistry and topology, and summarize metallation, peripheral functionalization, and heterostructure strategies, compiling representative performance metrics where reported. The collected studies indicate that appropriate metallation and \u03c0-extension enhance light absorption and charge separation; high crystallinity and accessible pores facilitate mass transport; and electronic coupling to conductive phases improves catalytic activity and selectivity in CO2 reduction. We close by outlining challenges and opportunities, including improving charge transport without sacrificing stability, pinpointing and quantifying active sites, and operando characterization to connect structure with function. This objective synthesis is intended to guide rational design of porphyrin-COFs for efficient and durable CO2 management.<\/jats:p>","DOI":"10.3390\/nano15231787","type":"journal-article","created":{"date-parts":[[2025,11,27]],"date-time":"2025-11-27T16:31:52Z","timestamp":1764261112000},"page":"1787","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Recent Advances in Porphyrin-Based COFs Boosting CO2 Photocatalytic and Electrocatalytic Conversion"],"prefix":"10.3390","volume":"15","author":[{"given":"Jiatong","family":"Yin","sequence":"first","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Jiangsu University, Zhenjiang 212013, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linxue","family":"Sang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Jiangsu University, Zhenjiang 212013, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2816-3234","authenticated-orcid":false,"given":"Yue","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Jiangsu University, Zhenjiang 212013, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"8313","DOI":"10.1021\/acs.chemrev.1c00065","article-title":"Creation from Confusion and Fusion in the Porphyrin World\u2014The Last Three Decades of N-Confused Porphyrinoid Chemistry","volume":"122","author":"Toganoh","year":"2022","journal-title":"Chem.
