In this study, porous vanadium-based single crystal powders are prepared by a conventional and simple method. The synthesised V₆O₁₃, VO₂, V₂O₃ and vanadium nitride (VN) single crystal powders are porous octahedral structured materials with approximately 4 μm particle sizes. Results show that the vanadium-based porous single crystal powders effectively catalyse ethane dehydrogenation at 680 °C, and the selectivity to ethylene is over 60%. VN exhibits excellent catalytic activity for ethane dehydrogenation at 680 °C with approximately 30% conversion of ethane and about 68% selectivity to ethylene, and it exhibits good stability even after working for 48 hours. The results of this study provide important value for designing and application of other metal-based porous single-crystal materials.

在多孔钒基单晶上促进乙烷脱氢

在这项研究中，多孔钒基单晶粉末是通过常规和简单的方法制备的。合成的V ₆ O ₁₃、VO ₂、V ₂ O ₃和氮化钒 (VN) 单晶粉末是多孔八面体结构材料，粒径约为 4 μm。结果表明，钒基多孔单晶粉末在680℃下可有效催化乙烷脱氢，乙烯选择性超过60%。VN在680°C下对乙烷脱氢表现出优异的催化活性，乙烷转化率约为30%，乙烯选择性约为68%，即使工作48小时后仍表现出良好的稳定性。该研究结果对其他金属基多孔单晶材料的设计和应用具有重要价值。
