“…This provides electrons to the conduction band of YPO 4 , which combine with the charge carriers (holes), producing an increase of |Z|. Opposite to this phenomenon, in n-type semiconductor materials, such as Gd 2 O 3 and Nd 2 O 3 , a decrease of |Z| in CO 2 has been observed [36,37]. The quantitative detection of CO 2 was evaluated by increasing the initial concentration of CO 2 in the air, from 200 to 800 ppm.…”

“…Metal oxide semiconductor (MOS) films, nanowires, nanocage, powder, and microspheres have been investigated [53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68][69] for carbon dioxide sensing. The sensors developed using this approach operate at a temperature range of 200-700 • C and can detect concentrations in the range of 100-10,000 ppm with a response time falling in the range of 3 s to 9.5 h. The recovery times are also in the range 4-700 s. The performance of an MOS sensor depends on its morphology and composition.…”

With the increasing utilization of fossil fuels in today’s technological world, the atmosphere’s concentration of greenhouse gases is increasing and needs to be controlled. In order to achieve this goal, it is imperative to have sensors that can provide data on the greenhouse gases in the environment. The recent literature contains a few publications that detail the use of new methods and materials for sensing these gases. The first part of this review is focused on the possible effects of greenhouse gases in the atmosphere, and the second part surveys the developments of sensors for greenhouse gases with coverage on carbon nano-materials and composites directed towards sensing gases like CO2, CH4, and NOx. With carbon dioxide measurements, due consideration is given to the dissolved carbon dioxide gas in water (moisture). The density functional calculations project that Pd-doped single-walled carbon nanotubes are ideal for the development of NOx sensors. The current trend is to make sensors using 3D printing or inkjet printing in order to allow for the achievement of ppb levels of sensitivity that have not been realized before. This review is to elaborate on the need for the development of greenhouse gas sensors for climatic usage by using selected examples.

“…In recent years, extensive attention has been paid to the nanostructured materials owing to their wide range of important and significant applications and interesting and unique properties [1][2][3][4][5]. Copper chromite (CuCr 2 O 4 ) is one of the most effective and attractive materials with interesting and specific properties, and has been studied widely due to its commercial applications in the chemical reactions, pollution abatement, photocatalytic H 2 production and solid propellants [6][7][8][9][10][11][12].…”

Pure copper chromite (CuCr 2 O 4 ) nanostructures were prepared via a new simple route. Nanostructures were synthesized by heat treatment in air at 900°C for 5 h, using powder, which was obtained by a solvent-free solidstate reaction (using ball milling) from 1:2 molar ratio of [Cu(en) 2 (H 2 O) 2 ]Cl 2 and [Cr(en) 3 ]Cl 3 Á3H 2 O as novel precursors. The effect of ball milling duration and calcination temperature on the morphology and size of copper chromite was investigated. It was found that these parameters have significant influence on the morphology and size of the CuCr 2 O 4 . The as-synthesized CuCr 2 O 4 nanostructures were characterized by means of several techniques such as X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, energy dispersive X-ray microanalysis, transmission electron microscopy and UVVis diffuse reflectance spectroscopy. Furthermore, the photocatalytic degradation of anionic dyes such as eosin Y, erythrosine and phenol red as water pollutants was performed to study the catalytic properties of as-prepared nanostructures.
