Nanocomposites of Zn_1-xFe_xO/reduced graphene oxide (Zn_1-xFe_xO/rGO, x = 0∼0.15) with carpet-like mesoporous structures have been simply synthesized via a low temperature hydrothermal method. FESEM and TEM results show that the hetero-assembly trend of Zn_1-xFe_xO and rGO is much more striking than that of Zn_1-xFe_xO self-assembly at 100 °C hydrothermal condition. The specific surface area and pore size tests indicate that rGO leads to the formation of slit holes with inclined panel structure, providing a large specific surface area for the nanocomposites. Mesoporous Zn_0.89Fe_0.11O has been proved to have the optimal gas response to ethanol at high operating temperatures, while Zn_0.89Fe_0.11O/rGO-10 (the content of rGO is 10 %) composite has a remarkable gas response (4.37) at low operating temperature and low ethanol concentration (160 °C, 2 ppm). In addition, the charge transport process and potential mechanism of gas response enhancement of Zn_1-xFe_xO/rGO composite have been discussed in detail, and this may be ascribed to the combined effect of P-N junctions and the interfacial coupling between Zn_1-xFe_xO and rGO.

采用低温水热法简单地合成了具有地毯状介孔结构的Zn _1-x Fe _x O /还原石墨烯纳米复合物（Zn _1-x Fe _x O / rGO，x = 0〜0.15）。FESEM和TEM结果表明，在100°C水热条件下，Zn _1-x Fe _x O和rGO的异质组装趋势要比Zn _1-x Fe _x O自组装的异质组装趋势更为明显。比表面积和孔径测试表明rGO导致形成具有倾斜面板结构的狭缝孔，从而为纳米复合材料提供了较大的比表面积。介孔锌_0.89铁_0.11已证明O在高温下对乙醇具有最佳的气体响应，而Zn _0.89 Fe _0.11 O / rGO-10（rGO的含量为10％）复合材料在低温下对气体具有出色的气体响应（4.37）。低乙醇浓度（160°C，2 ppm）。此外，还详细讨论了Zn _1-x Fe _x O / rGO复合材料的电荷传输过程和增强气体响应的潜在机理，这可能归因于PN结和Zn ₁之间的界面耦合的共同作用。_-x Fe _x O和rGO。
