This study introduces, for the first time, maltose-based polymers for photoreforming hydrogen generation studies, extending beyond the previously investigated glucose-based polymers. The findings are validated through both experimental and theoretical insights. The investigation explores how the structural complexity of disaccharides significantly influences the hydrophilicity of fluoro and non-fluoro polymers, as well as their effects on the photoreforming process. The structural properties of the synthesized polymers were characterized using various spectroscopic techniques, while their thermal properties were evaluated through TGA and DSC analysis. The glycopolymers with Pt/TiO₂ strongly influence the photoinduced charge separation and transfers; enabling enhanced H₂ production across a wide pH level. The fluoro-polymers with deacetylated maltose such as PPFBM-<em>b</em>-PMD and PPFPM-<em>b</em>-PMD synergistically increased the H₂ fuel production rate up to 1478 μmol g^-1h⁻¹ and 1363 μmol g^-1h⁻¹ compared to the non-fluoro glycopolymers. The improved hydrogen production may result from in-situ F doping of TiO₂ during the photoreforming process. Future studies will focus on optimizing conditions for large-scale biomass photoreforming, improving glycopolymer solubility, hydrophilicity, and electron-donating properties as substrates. First-principles based DFT calculations reveal that substituting F for surface O in Pt/TiO₂ creates conductive states near the conduction band, thereby enhancing electron mobility and photocatalytic performance, which aligns with the experimental findings.</div></div>","PeriodicalId":325,"journal":{"name":"Fuel","volume":"395 ","pages":"Article 135173"},"PeriodicalIF":6.7,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143687884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the ageing of AP with low-concentration Activated Copper Chromite (ACR) as a catalyst. AP pellets containing 0.4 % ACR, representative of typical industrial class propellant compositions, underwent accelerated cyclic ageing equivalent to four years of natural ageing. Subsequently, aged ACR was extracted and added into fresh AP and pelletized. The resulting pellets are characterised using burn rate tests, TGA, and DTA analyses. Results indicate a 12.3 % average decrease in burn rates upon ageing, alongside deteriorated decomposition characteristics compared to AP with un-aged ACR. The decomposition characteristics of AP with aged ACR are found to be shifting toward the pure AP decomposition characteristics. This shift indicates that the ageing process alters the decomposition properties of the AP–aged ACR mixture, causing it to behave like AP during decomposition. The activation energy of AP, AP+raw ACR and AP+aged ACR also shows similar trends in changes in activation energy proving deterioration in catalytic performance on AP. Ammonium TPD testing reveals a loss in the strength of Lewis acid sites in aged ACR, suggesting reduced efficiency. Additionally, Energy-Dispersive Spectroscopy Analysis demonstrates an increase in oxygen content in aged ACR. XRD tests show increase in copper oxide upon ageing of ACR and decrease in the percentage of copper chromium oxide. Propellants with raw and aged ACR were made and burn rates were measured. Burn rates were found to decrease in case of propellants with aged ACR. These findings underscore the importance of understanding the ageing process in AP-ACR systems and its implications for propellant performance.</div></div>","PeriodicalId":325,"journal":{"name":"Fuel","volume":"394 ","pages":"Article 135132"},"PeriodicalIF":6.7,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143681788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The activity of zeolites for NO-SCO exhibits a quasi-V-shaped curve with respect to temperature within this range, resulting in low activity. To enhance the catalytic activity of zeolite for NO-SCO at these temperatures, it’s crucial to achieve a low transition temperature, at which the mechanism of NO-SCO shifts. In this study, M−doped small-pore zeolite SSZ-13 catalysts (where M = Fe or Cu), along with H-SSZ-13 and Na-SSZ-13, were synthesized through a one-pot hydrothermal method for NO-SCO. NO-SCO tests show that Fe-SSZ-13 significantly lowers the transition temperature to around 100 °C, compared to Cu-SSZ-13, H-SSZ-13, and Na-SSZ-13, which have transition temperatures of about 150 °C, 125 °C, and 150 °C, respectively. As a result, Fe-SSZ-13 exhibits excellent NO-SCO activity, with NO conversions reaching 85 % at both 25 °C and 250 °C and exceeding 40 % across a broad temperature range of 25–350 °C at a WHSV of 12,000 mL·g⁻¹·h⁻¹. Characterization reveals that Fe-based species in Fe-SSZ-13 mainly exist as binuclear Fe species and isolated Fe ions. The former serves as the main active sites for NO-SCO, while the latter can stabilize NO⁺, adsorb NO, and generate nitrates and NO⁺, all of which collectively facilitate NO-SCO.
