ZIF-8 nanoribbons, with tunable morphology and pore structure, were synthesized by using the tri-block co-polymer Pluronic F127 as a soft template. The as-synthesized ZIF-8 nanoribbons were converted into carbon nanoribbons by thermal transformation with largely preserved morphology and porosity. The resulting carbon nanoribbons feature both micro- and meso-pores with high surface areas of over 1000 m g . In addition, nitrogen-doping in the carbon nanoribbons was achieved, as confirmed by XPS and EELS measurements. The hybrid carbon nanoribbons provide pseudo-capacitance that promotes electrochemical performance, rendering a high specific capacitance of up to 297 F g at a current density of 0.5 A g in a three-electrode system. A long cycle life was also demonstrated by recording a 90.26 % preservation of capacitance after 10 000 cycles of charge-discharge at a current density of 4.0 A g . Furthermore, a symmetrical supercapacitor is fabricated by employing the carbon nanoribbons, which shows good electrochemical performance with respect to energy, power and cycle life.

Hydrothermal synthesis is of considerable interest due to its low cost, simplicity and relatively low growth temperature (typically below 200 °C). Since the synthesis is performed in aqueous solutions (no organic solvents), it can also be safe and environmentally friendly (depending on precursor chemicals). Consequently, it has been a subject of intense research in recent years. In this article, we review recent progress in hydrothermal synthesis of zinc oxide nanomaterials, with focus on practical relevance for a variety of applications.

“…Second, the good gas sensing for NO x of the In 2 O 3 sensor can be ascribed to the single crystal In 2 O 3 and its own nanosheet structure which have a benecial effect on the performance of the In 2 O 3 sensor. 47,48 The ideal structure is considered to be single crystal, because such gas sensing materials can exhibit high electron conductivities, and have abundant interfacial active sites and excellent stability. 49,50 When the porous coupled with single crystallinity provides for the ease of gas diffusion and more active sites for the formation of reactive oxygen species.…”

Highly active and porous single-crystal In₂O₃ nanosheet for NO_x gas sensor with excellent response at room temperature

et al. 2017

Porous single-crystal In 2 O 3 nanosheet (ps-In 2 O 3 NS) was designed and prepared through a method of calcination after liquid reflux. Compared with the other In 2 O 3 with different surface morphologies, the ps-In 2 O 3 NS has gas sensing properties towards NO x at room temperature. Gas sensing data strongly demonstrate that this porous single-crystal In 2 O 3 nanosheet exhibits a distinguished response (89.48) and fast response time (16.6 s) to 97.0 ppm NO x . Meanwhile, the ps-In 2 O 3 NS sensor presents a favorable linearity and good selectivity, and the detection of NO x is down to ppb levels at room temperature. The enhancement of the sensing response is attributed to the porous, single-crystal and two dimensional nanosheet structure of the synthesized ps-In 2 O 3 NS, which has much higher BET surface area, effective gas diffusion of slit pores and thus provides more active sites for the reaction of NO x with surface-adsorbed oxygen ions. This work would be important for the low-cost and high performance of the In 2 O 3 material with highly promising applications in gas sensors.
