Four different preparation routes were used to synthesize Sr₂TiO₄ with the structure of layered perovskite: sol-precipitation (SP), co-precipitation (CO), citrate precursor (CT) and mechanochemical (MA) methods with further calcinations at 1100 °C. The XDR, XPS, BET, SEM techniques showed that the different preparation routes caused the formation of layered perovskite phase with different admixture phases, particle sizes and the surface enrichment with layered perovskite (for SP and MA samples) or strontium oxide (for CO and CT samples). The trend of increasing of CH₄ conversion and C₂-yield in oxidative coupling of methane at 800-900 °C was found to be the following: SP≈MA > CO > CT samples. The C₂-yield of the most active catalysts was measured to be about 12%.

四种不同的制备路线用于合成具有层状钙钛矿结构的Sr ₂ TiO ₄：溶胶沉淀（SP），共沉淀（CO），柠檬酸盐前体（CT）和机械化学（MA）方法以及在1100°煅烧的方法C。XDR，XPS，BET，SEM技术表明，不同的制备途径会导致形成具有不同混合相，粒径的钙钛矿层状相，并形成具有钙钛矿层（对于SP和MA样品）或氧化锶（对于CO和CT样本）。发现甲烷在800-900°C的氧化偶合中CH ₄转化率和C ₂产率增加的趋势为：SP≈MA> CO> CT样品。C ₂活性最高的催化剂的产率经测量为约12％。
