Rietveld refinement analysis confirmed the successful substitution of Mg²⁺ by Co²⁺/Ni²⁺, as indicated by corresponding changes in cell volumes. These solid solutions display tunable blue and purple hues, influenced by the doping levels of Co²⁺/Ni²⁺. Compared to commercial cobalt blue (CoAl₂O₄), the synthesized blue oxides significantly lowered Co²⁺ levels while achieving the desired color properties.

The XPS results demonstrate the concentration of Mo⁵⁺ and Mo⁶⁺ present in each sample. The results of the VSM experiments demonstrated that the observed change in the magnetic response of MoO₃ is due to the intensity of the material's response being comparable to that of the sample holder's response.

The powder samples of the NASICON-type phosphates were synthesized by the Pechini technique. Their phase purity and structure characterization were performed using XRD, IR spectroscopy, SEM, BET and BJH methods. Structural data indicated that the transition from La to Dy was accompanied by a decrease in M − O bond lengths, which is compensated by longer neighboring Ti–O bonds, ultimately leading to greater distortion of the surrounding octahedra. The catalytic activity of M_0.33Ti₂(PO₄)₃ (M − La, Sm, Dy) phosphates has been studied in ethanol reforming reactions in the temperature range of 240–400 °C. The regularities of changes in the catalytic properties in the La→Sm→Dy series have been traced. The selectivity of ethanol conversion was found to depend on the phosphate composition. The best alcohol conversion was achieved on Dy-phosphate at 400 °C with an ethylene selectivity of 66 %.</div></div>","PeriodicalId":432,"journal":{"name":"Solid State Sciences","volume":"162 ","pages":"Article 107865"},"PeriodicalIF":3.4,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143445392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
