“…In the present work, we observed a maximum responsivity i.e 0.011 AW -1 which is reasonable better even at minimum power intensity at 5 mWcm -2 . In addition, the responsivity of the annealed film is one order higher than the as- The external quantum efficiency (EQE) can be determined by the equation [41]; it provides the amount of conversion of the incident photons to electric current [42].…”

“…161,162 Still, there are some shortcomings that hinder the large-scale practical application of this technology. The main shortcomings of photocatalysis can be described as follows: 163 photocatalysts with a wide band gap need the simulation of UV Nowadays, a variety of methods have been adopted to modify TiO 2 to overcome those shortcomings, such as doping with other elements. Dai et al synthesized nitrogen-doped reduced graphene (N-GR)/TiO 2 to investigate the polar adsorption and photodegradation characteristics of acetaldehyde (polar) and ethylene (nonpolar).…”

“…Therefore, it is widely used in the fields of environmental and chemical engineering. , Still, there are some shortcomings that hinder the large-scale practical application of this technology. The main shortcomings of photocatalysis can be described as follows: photocatalysts with a wide band gap need the simulation of UV light, resulting in low solar radiation utilization, and the recombination of hole–electron pairs decreases the photocatalytic activity, which deactivates the catalyst eventually.…”

Ethylene acts as an important hormone to trigger the ripening and senescence of fruits and vegetables (F&V). Thus, it is essential to eliminate trace ethylene and prevent F&V losses effectively. There are several technologies currently applying to control the ethylene concentration in the storage and transportation environment, including adsorption, gene modification, oxidation, etc. These protocols will be compared, and special attention will be paid to the low-temperature catalytic oxidation that has already been applied to practical production in this review. The active sites, supports, and reaction and deactivation mechanism of the catalysts for the low-temperature ethylene oxidation will be discussed and evaluated systematically to provide new insights for the development of effective catalysts, along with the suggestion of some perspectives for future research on this important catalytic system for F&V preservation.

In this report, we have discussed the performance of highly sensitive CdSe based photodetector. The CdSe thin films were prepared by thermal evaporation method on the cleaned glass substrate at room temperature. The influence of post annealing on the optical, morphological, structural and photo-electrical properties at different temperatures were investigated. The formation of polycrystalline CdSe ﬁlms was confirmed from X-ray diﬀraction (XRD) and Raman studies. The change in surface morphology along with the average grain size of ﬁlms were observed by field emission scanning electron microscopy (FESEM). The stoichiometric ratio of Cd and Se elements in the deposited ﬁlms was verified from Energy dispersive X-ray spectroscopy (EDS). The change in various optical parameters like absorption coeﬃcient (α), extinction coeﬃcient (k), optical band gap (Eg), refractive index (n) etc. of the studied ﬁlms were calculated from the UV-Visible measurement. Importantly, the band gap values were decreased and increased with different annealing temperatures. The CdSe film annealed at 300 °C showed good photo-response and the corresponding optical properties which make them suitable for photodetector applications.
