Lanthanum (La) was chosen as the A-site cation whereas iron (Fe) and manganese (Mn) were chosen as the B-site cations, respectively. La, Fe, and Mn were incorporated into the perovskite structure (LaFe_1-xMn_xO_3−δ) at various Fe/Mn ratios to tailor the equilibrium oxygen partial pressures for CO₂-splitting and methane partial oxidation. Compared to the standalone redox pairs of Fe and Mn (i.e., Fe₂O₃/Fe₃O₄, Fe₃O₄/FeO, and Mn₂O₃/Mn₃O₄) which, from a thermodynamic standpoint, favor the complete combustion of CH₄, the perovskite structured redox catalysts (RCs, i.e., LaFe_1-xMn_xO_3−δ) favored the selective oxidation of CH₄ to syngas. In addition, impregnating the RCs with 1 wt% ruthenium (Ru) led to a significant improvement in their redox kinetics without affecting their redox thermodynamics. The Ru-impregnated, perovskite structured RCs (i.e., LaFeO₃, LaFe_0.625Mn_0.375O₃, and LaFe_0.5Mn_0.5O₃ ) exhibited excellent redox performance in terms of the syngas yield (92 – 100 %) and CO₂ conversion (95–98 %). Long-term redox testing over Ru-impregnated LaFeO₃ and LaFe_0.5Mn_0.5O₃ demonstrated relatively stable performance for 100 redox cycles whereas activity loss was observed for LaFe_0.625Mn_0.375O₃, LaFe_0.375Mn_0.625O_3, and LaMnO₃ respectively. Among RCs containing both Mn and Fe, LaFe_0.5Mn_0.5O₃ exhibited the best performance, maintaining satisfactory activity over 100 cycles and higher oxygen capacity. XRD and XPS analysis suggest that the ability to regenerate the perovskite phase under a CO₂ environment and a near surface A:B site cation ratio close to the perovskite stoichiometry would likely correspond to more stable performance. Additionally, the inclusion of Mn on the B-site enhances the coke resistance of the redox catalyst when compared to undoped LaFeO₃.</div></div>","PeriodicalId":264,"journal":{"name":"Catalysis Today","volume":"462 ","pages":"Article 115546"},"PeriodicalIF":5.3,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145046887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, two methods of preparing HA - containing catalysts were explored: i) conventional route using bone char (BC) from BW calcined at 500–900 °C, and ii) microwaves route using aqueous phase extraction from BW by a microwave (MW) -assisted process at 95 °C. BC mainly consisted of B-type HA, in which carbonate groups replace phosphate in the structure; however, its low surface area limited its catalytic performance. Modification with silica, MW treatment and surfactant charge had a critical effect on the formation of the porous structure, and consequently, on increasing the surface area of the composite catalysts. Cationic surfactants promoted silica network formation and resulted in improved porous structures due to their weaker interaction with the positively charged BC. The obtained HA-containing catalysts were demonstrated to be effective platforms for immobilising metallic species. Incorporating Ti and Zn by direct synthesis generated highly dispersed active sites, as confirmed by physicochemical characterization. Notably, an increase in sea buckthorn pyrolysis temperature (from 250 °C to 600 °C) was observed after just 5 min of MW irradiation using catalysts produced via the MW-assisted method, indicating enhanced heat transfer within the reactor.

This is conducive to provoke water-gas shift (WGS) preferentially via redox mechanism that has been controversial in terms of rate-determining step (RDS) and major activator. To this end, Kaolinite-supported Pd_XAg_4-X alloys were synthesized to impart M_II^3+/4+-O^2--M_I^δ+-O^2--M_II^3+/4+ interfaces, where the redox mechanism can be accelerated using M_I^δ+ or proximal oxygen vacancy (O_V) as the main activator. The amounts and electron (e^-) affinity of M_I^δ+/O_V species varied with dissimilar X values or their exposure to hydro-thermal aging (HT) environments, thereby linking with WGS kinetic parameters of the catalysts. The hierarchies of the energy barriers for the HT-unsubjected/subjected catalysts were con-current to their trends on e^- affinity with O_V species rather than those with M_I^δ+ counterparts. This demonstrated that the RDS is either CO₂ desorption from M_I^δ+/O_V or H₂O homolysis on O_V.

Catalysts consisting of noble metals that are stable in acidic solutions and carbon supports without acidic sites causing side reactions have several advantages, such as the high activity and ease of separation. To enhance catalytic activity, the surface area of the active metal should be increased. However, conventional impregnation methods are not completely suitable for this purpose because of the weak metal–carbon interactions. To solve this problem, a preparation method using an ion-exchange resin as a precursor for the carbon support was employed. In this study, we investigated the effect of the preparation method of carbon-supported Pt catalysts on their catalytic activity for the liquid-phase decomposition of formic acid. The catalysts prepared from ion-exchange resins exhibited Pt loadings of approximately 26–28 wt% and Pt particle sizes of 2–3 nm; therefore, this method can realize a higher dispersion degree of Pt nanoparticles than an impregnation method. Moreover, the produced catalysts demonstrated a higher activity for the dehydrogenation of formic acid than those of the catalysts prepared by the impregnation method. Additionally, the carbonization temperature strongly affected the catalyst properties, such as the pore size and metal accessibility. Consequently, the catalyst activity for the decomposition of formic acid varied depending on the carbonization temperature.
