This review presents the results of cutting-edge research on chemiresistive gas sensors in Korea with a focus on the research activities of the laboratories of Professors Sang Sub Kim and Hyoun Woo Kim. The advances in the synthesis techniques and various strategies to enhance the gas-sensing performances of metal-oxide-, sulfide-, and polymer-based nanomaterials are described. In particular, the gas-sensing characteristics of different types of sensors reported in recent years, including core–shell, self-heated, irradiated, flexible, Si-based, glass, and metal–organic framework sensors, have been reviewed. The most crucial achievements include the optimization of shell thickness in core–shell gas sensors, decrease in applied voltage in self-heated gas sensors to less than 5 V, optimization of irradiation dose to achieve the highest response to gases, and the design of selective and highly flexible gas sensors-based WS2 nanosheets. The underlying sensing mechanisms are discussed in detail. In summary, this review provides an overview of the chemiresistive gas-sensing research activities led by the corresponding authors of this manuscript.

“…The core-shell structure has also been successfully applied for different application such as solar cell, supercapacitor and gas sensor. [18][19][20] In the present study, three-dimensional core-shell CuCo 2 O 4 nanowires@CuCo 2 O 4 nanosheets for SCs were designed to further improve the properties of the material. The use of CuCo 2 O 4 nanowires as core materials was based on the consideration of high specific capacitance of multiple oxidation states and fast reversible Faraday reaction.…”

A reasonable electrode structure is important to improve the performance of supercapacitors. In this work, Leaf-like CuCo 2 O 4 @CuCo 2 O 4 nanowires grown erectly on Ni foam substrate were prepared by two-step hydrothermal method to form a mutually perpendicular core-shell nanostructure. The binder-free CuCo 2 O 4 @CuCo 2 O 4 nanowires were more likely to benefit from multidimensional synergistic effect and better conductivity, revealing a high specific capacitance of 5.86 F cm À 2 at 5 mA cm À 2 and good cycle stability (90.2 % after 8000 cycles). In addition, the SC based on CuCo 2 O 4 @CuCo 2 O 4 battery-type electrodes exhibited good flexible properties. The environment friendly and low cost CuCo 2 O 4 @CuCo 2 O 4 //AC flexible SCs perform a high energy density of 0.35 mWh cm À 2 at a power density of 8 mW cm À 2 . The results indicated that CuCo 2 O 4 @CuCo 2 O 4 core-shell materials have high application value, thus providing a new type of advanced electrode for flexible SCs.

“…In addition, high hydrogen concentrations lead to a decrease in the amount of oxygen and consequently to suffocation, neuronal apoptosis and other neuronal disorders [ 2 , 16 , 17 ]. Because hydrogen cannot be detected directly by the human senses by odor or color, and due to its small atomic radius [ 18 , 19 ], it is necessary to perform this detection by means of specialized sensors [ 3 , 4 , 19 , 20 ]. With regard to the lack of color and odor of hydrogen, current studies aim to attribute these characteristics to it [ 21 ].…”

The development of hydrogen sensors has acquired a great interest from researchers for safety in fields such as chemical industry, metallurgy, pharmaceutics or power generation, as well as due to hydrogen’s introduction as fuel in vehicles. Several types of sensors have been developed for hydrogen detection, including resistive, surface acoustic wave, optical or conductometric sensors. The properties of the material of the sensitive area of the sensor are of great importance for establishing its performance. Besides the nature of the material, an important role for its final properties is played by the synthesis method used and the parameters used during the synthesis. The present paper highlights recent results in the field of hydrogen detection, obtained using four of the well-known synthesis and deposition methods: sol-gel, co-precipitation, spin-coating and pulsed laser deposition (PLD). Sensors with very good results have been achieved by these methods, which gives an encouraging perspective for their use in obtaining commercial hydrogen sensors and their application in common areas for society.
