“…It could be expected that derivation of novel applications of carbonaceous nanomaterials by integration with other technologies, such as sensor or quantum electronic technology, would cover much broader perspectives (Bittencourt et al, 2006;Espinosa et al, 2007;Balazsi et al, 2008;Hashishin, and Tamaki, 2008;Ghasempour and Zad, 2009). In this review, some typical examples of novel applications of carbonaceous nanomaterials are summarized.…”

“…Preventive actions against natural or artificial emission of some toxic exhausted gas have been accomplished by many research teams around the world (Bittencourt et al, 2006;Espinosa et al, 2007;Balazsi et al, 2008;Hashishin and Tamaki, 2008). With the excellent conductivity, carbonaceous materials would be hybridized with some semi-conductor nanoparticles for improving sensing capability.…”

An increase in global consumption has led to an exponential increase in industrial production activities which inevitably results in overwhelming remain of industrial waste. Consequently it has driven increasing attentions of research and development teams in various countries to propose and investigate novel methodologies to utilize such industrial waste. Instead of using as alternative energy sources, usage of industrial waste for production of carbonaceous nanomaterials has been examined via various routes, such as catalytic pyrolysis, hydrothermal treatment and so on. Meanwhile, for sustainable and secure continuity of the carbonaceous nanomaterial production, broad spectra of promising applications have also been examined. Among those emerging applications, utilization of carbonaceous nanomaterials in pollution control and prevention has been focused worldwide. Therefore, in this review, relevant research works focusing on catalytic pyrolysis of carbonaceous industrial waste for carbonaceous nanomaterial production were comprehensively analyzed and summarized. In addition, promising applications involving with antibiotic removal, spilled oil handling and pollutant gas detection were also reviewed.

“…Анализ литературы свидетельствует, что для существенного повышения газоадсорбционных свойств и электропроводности полупроводнико-вого оксида металла обычно достаточно 0,1-2 % мас. добавки очищенных УНТ, причем оптималь-ное количество добавки в данном интервале зави-сит от выбранного оксида металла [10]. На осно-вании исследования температурной зависимости электрического сопротивления для изготовления датчиков нами выбрано значение концентрации добавки, равное 2,1 % мас.…”

“…Данный интервал, вероятно, выходит за пределы рабочей температу-ры датчиков на использованных подложках (токи нагрева 31-51 мА), и полноценная его реализация требует использования подложек, позволяющих использовать более высокие токи нагрева. Столь высокая чувствительность к NO 2 материалов, со-держащих УНТ, отмечалась ранее в работе [10]. Известно также [10], что в большинстве слу-чаев экстремально высокая чувствительность к NO 2 материалов, содержащих УНТ, сопровожда-ется также возрастанием времени восстановле-ния (τ 90 ), что наблюдается и в нашем случае.…”

Sensor technology has an important effect on many aspects in our society, and has gained much progress, propelled by the development of nanoscience and nanotechnology. Current research efforts are directed toward developing high-performance gas sensors with low operating temperature at low fabrication costs. A gas sensor working at room temperature is very appealing as it provides very low power consumption and does not require a heater for high-temperature operation, and hence simplifies the fabrication of sensor devices and reduces the operating cost. Nanostructured materials are at the core of the development of any room-temperature sensing platform. The most important advances with regard to fundamental research, sensing mechanisms, and application of nanostructured materials for room-temperature conductometric sensor devices are reviewed here. Particular emphasis is given to the relation between the nanostructure and sensor properties in an attempt to address structure-property correlations. Finally, some future research perspectives and new challenges that the field of room-temperature sensors will have to address are also discussed.
