Excessive-temperature catalytic ammonia combustion (HT-CAC) is a promising technique for the clear and environment friendly utilization of power carried by inexperienced NH3 fuels. A key problem lies in growing catalysts that supply excessive ammonia oxidation exercise, wonderful thermal stability, and excessive N2 selectivity. On this research, we synthesized a high-entropy fluorite oxide aerogel (HEFOA) by way of supercritical drying. The improved chemical dysfunction leads to a better particular floor space and improved thermal resistance in comparison with its low-entropy counterpart (LEFOA). Incorporating Pt via a one-pot technique yielded Pt@HEFOA, which demonstrated excellent catalytic exercise and long-term stability throughout a 50-hour HT-CAC check at 1200 °C. This work opens new avenues for designing sturdy ammonia combustion catalysts that stay efficient beneath excessive temperatures, which might contribute to the event of a sustainable NH₃-based hydrogen power cycle.
