Abstract Copper (Cu) and its oxides are well-known catalysts for thermal decomposition of ammonium perchlorate (AP). Nano Cu/Cu2O dispersed on graphitic carbon nitride (g-C3N4) based nanocomposites were synthesised by single displacement reaction and its effect on thermal decomposition of AP was studied. As-prepared catalysts were characterized using various techniques. The catalytic activity of the synthesised products was evaluated using Thermogravimetry-Differential Scanning Calorimetry. Among the catalysts prepared, Cu/g-C3N4-80:20 with an optimum surface area of 15 m2 g−1 showed excellent catalytic activity towards thermal decomposition of AP. Presence of 0.2 % of Cu/g-C3N4-80:20 catalyst boosted the rate of high temperature decomposition reaction of AP by decreasing the peak decomposition temperature from 370 to 320 °C and also by liberating ∼ 1.3 times higher energy of decomposition as compared to pristine AP. ∼ 23 times hike in rate of the reaction could be achieved in the presence of 0.2 % Cu/g-C3N4-80:20 catalyst.

高氯酸铵的分解：探索基于纳米 Cu/Cu2O 分散在石墨氮化碳上的纳米复合材料的催化活性

摘要 铜 (Cu) 及其氧化物是众所周知的高氯酸铵 (AP) 热分解催化剂。通过单置换反应合成了分散在石墨氮化碳（g-C3N4）基纳米复合材料上的纳米Cu/Cu2O，并研究了其对AP热分解的影响。使用各种技术表征所制备的催化剂。使用热重-差示扫描量热法评估合成产物的催化活性。在制备的催化剂中，最佳表面积为 15 m2 g-1 的 Cu/g-C3N4-80:20 对 AP 的热分解表现出优异的催化活性。存在 0.2% 的 Cu/g-C3N4-80：20 催化剂通过将峰值分解温度从 370°C 降低到 320°C 并通过释放比原始 AP 高 1.3 倍的分解能来提高 AP 的高温分解反应速率。在 0.2% Cu/g-C3N4-80:20 催化剂存在下，反应速率可提高约 23 倍。
