Gas sensors based on metal oxides semiconductor (MOS) have attracted extensive attention from both academic and industry. ZnO, as a typical MOS, exhibits potential applications in toxic gas detection, owning to its wide band gap, n-type transport characteristic and excellent electrical performance. Meanwhile, doping is an effective way to improve the sensing performance of ZnO materials. In this review, the effects of different types of doping on morphology, crystal structure, band gap and depletion layer of ZnO materials are comprehensively discussed. Theoretical analysis on the strategies for enhancing the sensing properties of ZnO is also provided. This review puts forward the reasonable insight for designing efficient n-type ZnO-based semiconductor oxide sensing materials.

“…For example, H 2 , H 2 S, and C 2 H 4 are common pollutant gases that pose a serious risk to human health [ 126 , 127 ]. This scenario requires unified gas sensors with excellent selectivity, reliability [ 128 ], high sensitivity [ 129 ], fast response, long-term stability, cost-effectiveness, and workability at low gas concentrations [ 130 , 131 , 132 , 133 ]. An ample gas-sensing span is also necessary [ 134 ]; the ideal range of sensing gas detectors is 10–1000 ppm [ 135 ].…”

This review summarizes the recent research on nitride nanostructures and their applications. We cover recent advances in the synthesis and growth of porous structures and low-dimensional nitride nanostructures via metal-assisted photochemical etching and molecular beam epitaxy. The growth of nitride materials on various substrates, which improves their crystal quality, doping efficiency, and flexibility of tuning performance, is discussed in detail. Furthermore, the recent development of In(Ga)N nanostructure applications (light-emitting diodes, lasers, and gas sensors) is presented. Finally, the challenges and directions in this field are addressed.

The electrochemical sensing is a potential method for detection of trace toxic substance. Herein, the heterojunction of netlike ZnO/BiOCl nanosheets was constructed for the enhanced electrochemical detection of ammonia. Cyclic voltammetry and linear sweep voltammetry were used to investigate the electrochemical performance. The results show that the ZnO/BiOCl‐modified electrode exhibits higher sensitivity towards ammonia compared with the ZnO and BiOCl‐based electrodes, which is ascribed to band structure and fast electron transfer. The high response of 11.8 μA mM−1 and a low detection limit (LOD) of 0.25 μM are achieved. In addition, the ZnO/BiOCl material exhibits high selectivity, repeatability and stability. The better linear relationship between concentration and current (R2=0.99) is significant for quantitative detection of ammonia, implying that netlike ZnO/BiOCl nanosheets can serve as electrochemical sensing platform for detecting toxic substance. This research provides a strategy for fabricating two‐dimensional netlike materials and regulating heterojunctions used for electrochemical application.
