This review systematically examines the four functional categories of bed materials – inert, sorbent, oxygen carrier, and catalytic – synthesizing current knowledge on their performance characteristics, degradation mechanisms, and application constraints. Quantitative analysis of operational parameters reveals that inert materials, such as silica-based beds, require combustion temperatures of 1000–1200 °C to achieve complete fuel conversion, resulting in thermal NOx formation and agglomeration risks that initiate at temperatures between 660 and 980 °C depending on feedstock composition. In contrast, catalytic systems enable stable operation at 650–750 °C, achieving combustion efficiencies exceeding 99.9% while maintaining fluidization stability. Sorbent materials employed for carbon capture demonstrate CO₂ absorption capacity but exhibit progressive deactivation over multiple cycles, with mechanical attrition rates representing a limiting factor for long-term application. Oxygen carriers utilized in chemical looping configurations exhibit oxygen transport capacities ranging from 2 to 8 wt%, with operational lifetimes estimated between 2000 and 5000 h under continuous fluidized bed conditions. Mechanical degradation through attrition and fragmentation constitutes a universal constraint across all material classes, directly impacting process economics and operational continuity.

In this study, blue-green algae-derived carbon quantum dots (BGA-CQDs) were introduced as sustainable modifiers for a gas diffusion electrode (GDE) cathode to enhance TCPP degradation.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> RESULTS</h3>\u0000 \u0000 <p>Compared with the pristine GDE, the BGA-CQDs-modified GDE (CQDs-GDE) exhibited improved electrochemical activity and pollutant removal performance. Under the optimal conditions of CQDs:CB = 1:2, 50 mM Na₂SO₄, pH 3, and an aeration rate of 200 mL min⁻¹, the EF system achieved 91.17% and 88.78% of COD and TOC removal within 180 min, respectively. In addition, the pseudo-first-order rate constant reached 0.0131 min⁻¹, while the electrical energy consumption was 10.55 kWh kgCOD⁻¹. Moreover, the modified GDE maintained over 70% COD removal even after six consecutive cycles, whereas the pristine GDE decreased to 36.75%. The combined LC–MS analysis and DFT calculations indicated that TCPP degradation mainly proceeded through hydroxylation, dechlorination, and ester bond cleavage, to yield less toxic intermediates.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> CONCLUSION</h3>\u0000 \u0000 <p>BGA-CQDs effectively enhanced the catalytic activity and stability of the GDE cathode in the EF process. This study demonstrates a sustainable strategy for converting algal biomass into functional electrode materials for efficient degradation of organophosphate pollutants. © 2026 Society of Chemical Industry (SCI).</p>\u0000 </section>\u0000 </div>","PeriodicalId":15335,"journal":{"name":"Journal of chemical technology and biotechnology","volume":"101 9","pages":"1830-1842"},"PeriodicalIF":2.7,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148662875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
