Abstract

Nanomaterials adorned on graphene comprise an essential component of a wide range of devices wherein graphene-based copper oxide nanocomposites have garnered significant attention in recent years. Copper oxides (CuO and Cu₂O) are semiconductors with distinctive optical, electrical, and magnetic properties. Their earth abundance, low cost, narrow bandgap, high absorption coefficient, and low toxicity of copper oxides are just a few key advantages. CuO is superior to Cu₂O in optical switching applications because of its narrower bandgap. Therefore, integrating graphene with copper oxides renders the ensuing nanocomposites much more valuable for various applications. Not surprisingly, a wide range of promising synthesis and processing techniques have been considered, focusing on multiple appliances such as sensors, energy storage, harvesting, and electrocatalysis. Herein, the most recent synthesis techniques and applications of doped, undoped, and hierarchical structures of CuO/Cu₂O-graphene-based nanocomposites are deliberated, including the potential future usages.

氧化铜/石墨烯基复合材料：合成方法、设备和最新进展

装饰在石墨烯上的纳米材料是各种设备的重要组成部分，其中石墨烯基氧化铜纳米复合材料近年来备受关注。氧化铜（CuO 和 Cu2O）是一种半导体，具有独特的光学、电学和磁学特性。铜氧化物在地球上资源丰富、成本低廉、带隙窄、吸收系数高、毒性低，这些只是铜氧化物的几个主要优点。由于带隙较窄，氧化铜在光开关应用中优于氧化亚铜。因此，将石墨烯与铜氧化物结合在一起可使纳米复合材料在各种应用中发挥更大的价值。毫不奇怪，人们已经考虑了多种前景广阔的合成和加工技术，重点关注传感器、能量存储、采集和电催化等多种应用。本文讨论了掺杂、未掺杂和分层结构的铜氧化物/铜氧化物-石墨烯基纳米复合材料的最新合成技术和应用，包括未来的潜在用途。
