Defect engineering has emerged as a powerful strategy to overcome these limitations by deliberately creating and regulating structural imperfections within porous frameworks. However, current knowledge remains scattered across specific material families or individual photocatalytic applications, and a unified understanding of how different defects control photocatalytic behaviour in porous materials is still lacking. In this review, we highlight the role of defect engineering in the molecular design of porous photocatalysts, covering missing metal nodes and linkers in metal-organic frameworks, structural defects and dopant sites in covalent organic frameworks, and vacancy-related defects in zeolites and oxide frameworks. Particular emphasis is placed on how defect type, concentration and spatial distribution influence light absorption, bandgap regulation, charge separation, surface reactivity, adsorption behaviour and product selectivity. The review further compares major defect-generation strategies, including thermal treatment, heteroatom doping, plasma activation, ligand modulation and chemical reduction, together with advanced characterisation and theoretical tools used to identify and quantify defect sites. By linking defect chemistry with photocatalytic mechanisms, this review provides a structure-defect-activity framework for understanding performance enhancement in H₂ evolution, CO₂ reduction, N₂ fixation, selective oxidation and pollutant degradation. The novelty of this work lies in its cross-material comparison of defect-engineered porous photocatalysts and its emphasis on translating defect control into rational design principles for stable, selective and solar-responsive photocatalytic systems.</div></div>","PeriodicalId":18322,"journal":{"name":"Materials Today Sustainability","volume":"35 ","pages":"Article 101432"},"PeriodicalIF":9.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148854029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alkali chlorides largely preserve precursor composition and exhibit minimal templating, with NaCl being mostly inert. In contrast, alkaline earth chlorides strongly influence carbonization. MgCl₂ functions as an effective templating agent while inducing significant compositional changes, producing highly porous carbons with high surface areas (up to 2648 m²/g) and modifying nitrogen configurations. CaCl₂ primarily acts as a template, generating porosity while maintaining precursor chemistry. Precursor structure also matters: adenine forms tubular morphologies with MgCl₂, unlike guanine. Electrochemical measurements reveal that MgCl₂-derived carbons, particularly adenine-MgCl₂, showed the best performance in supercapacitors and Zn-ion capacitors due to their high surface area, accessible microporosity, and moderate nitrogen content.

In this work, superhydrophilic and underwater-superoleophobic stainless-steel mesh (SSM) membranes are fabricated through acid activation, seeding, and chemical bath deposition. The effects of surface activation are first examined by comparing SSM activated with HNO₃ (SSMH) and SSM activated with piranha solution (SSMP), demonstrating that piranha activation enables more effective surface functionalization for subsequent coating. SSMP is then seeded with either ZnO nanoparticles or g-C₃N₄ nanosheets prior to ZnO growth. The ZnO nanoparticles produce nanorod structures (SSMP/ZnO/ZnO), while g-C₃N₄ nanosheets induce flower-like ZnO domains (SSMP/g-C₃N₄/ZnO).

A significantly enhanced gravity-driven water flux of 125,659.71 L m⁻² h⁻¹ is achieved by SSMP/g-C₃N₄/ZnO, exceeding that of SSMP/ZnO/ZnO (103,416.36 L m⁻² h⁻¹), while preserving high and stable separation efficiency for at least 40 reuse cycles. Furthermore, SSMP/g-C₃N₄/ZnO sustains strong underwater oil repellency and high separation efficiency under acidic, alkaline, saline, hot, and cold conditions.

A variety of characterization techniques were employed to characterize the physicochemical structure of this synthesized nano-adsorbent. Comprehensive characterizations using XRD, FTIR, FE-SEM, TEM, XPS, and BET provided concrete evidence of the development of a TiO&lt;sub&gt;2&lt;/sub&gt;-coated CuWO&lt;sub&gt;4&lt;/sub&gt; core-shell structure. Characterizations such as XRD and FTIR confirmed the existence of amorphous CuWO&lt;sub&gt;4&lt;/sub&gt; and TiO&lt;sub&gt;2&lt;/sub&gt; phases with chemical bonding at the interface between CuWO&lt;sub&gt;4&lt;/sub&gt; and TiO&lt;sub&gt;2&lt;/sub&gt;.

XPS results indicated that the outer shell of TiO&lt;sub&gt;2&lt;/sub&gt; is enriched in Ti, thus showing that the coating was complete. The Box-Behnken design (BBD) optimized methodology was employed to optimize the operational variables such as adsorbent dosage, CIP concentration, solution pH, and contact time. The findings achieved nearly complete CIP (99.0 ± 0.3%) adsorption at a CIP concentration of 10 mg/L, an adsorbent dosage of 340 mg/L, and a contact time of 40 min at neutral pH (7.0). The same optimized conditions were also applied for MB dye adsorption, and complete dye adsorption (100% of MB) was achieved in only five (5) minutes of treatment. The adsorption followed pseudo-second-order (PSO) kinetics. The isotherm modeling results indicated that the Langmuir model provided the best fit with R&lt;sup&gt;2&lt;/sup&gt; values of &gt; 0.99, exhibiting maximum monolayer adsorption capacities (q&lt;sub&gt;m&lt;/sub&gt;) of 113.4 ± 6.4 mg/g for CIP at 30 °C, after which the capacities decreased with increasing temperature, indicating exothermic adsorption.

Although a good PSO fit usually suggests chemisorption, the adsorption rate here was actually controlled by strong non-covalent interactions (electrostatic attraction, hydrogen bonding, surface complexation, and π-π stacking) rather than true covalent bond formation.
