“…İnce filmlerin kırınım modelleri karşılaştırıldığında, aralarında ciddi fark gözlemlenmedi. İnce filmlerde katkılanan element ve bileşikleri ile ilgili herhangi bir pik tespit edilemedi [29][30][31]. Bu, tüm ince filmlerde aynı kristal fazın mevcut olduğu gösterir [32].…”

Çalışmamızda, bakır oksit ve bor katkılı bakır oksit ince filmler sprey piroliz yöntemi ile sentezlenmiştir. Bu ince filmlerin fiziksel özelliklerini belirlemek için XRD ve SEM ölçümleri yapılmıştır. XRD sonuçları incelendiğinde filmlerin monoklinik yapıda olduğu görülmüştür. Elde edilen bu ince filmlerin fotokatalitik aktiviteleri incelenmiştir. Fotokatalitik inceleme ksenon lamba altında metil mavisi boyar madde kullanılarak yapılmıştır. Elde edilen sonuçlarda ince filmlerin metil mavisi üzerinde yüksek fotokatalitik bozunma oranlarının olduğunu göstermiştir. Fotokatalitik deney sonuçları, bor katkılama miktarının bozunma verimini ve reaksiyon süresini olumlu etkilediğini göstermiştir. Buradan bor katkılı bakır oksit ince filmlerin metil mavisi için etkili bir fotokatalizör olduğunu gösterdi. Sonuç olarak, bor katkılı bakır oksit ince filmlerin metil mavi boya içeren atık sularda fotokatalitik bozunma için potansiyel aday olduğu kabul edilebilir.

“…[26] The main carrier of charge in n-type materials is free electrons, while that is holes in p-type materials. [27] For ntype sensors, the sensing process is actually the adsorptiondesorption process of oxygen molecules on the surface of the sensing material. [6a,28] In the atmosphere, oxygen molecules adsorbed on the surface of n-type semiconductor materials form adsorbed oxygen.…”

Gas sensors based on metal oxides semiconductor (MOS) have attracted extensive attention from both academic and industry. ZnO, as a typical MOS, exhibits potential applications in toxic gas detection, owning to its wide band gap, n-type transport characteristic and excellent electrical performance. Meanwhile, doping is an effective way to improve the sensing performance of ZnO materials. In this review, the effects of different types of doping on morphology, crystal structure, band gap and depletion layer of ZnO materials are comprehensively discussed. Theoretical analysis on the strategies for enhancing the sensing properties of ZnO is also provided. This review puts forward the reasonable insight for designing efficient n-type ZnO-based semiconductor oxide sensing materials.

The environmental crisis, due to the rapid growth of the world population and globalisation, is a serious concern of this century. Nanoscience and nanotechnology play an important role in addressing a wide range of environmental issues with innovative and successful solutions. Identification and control of emerging chemical contaminants have received substantial interest in recent years. As a result, there is a need for reliable and rapid analytical tools capable of performing sample analysis with high sensitivity, broad selectivity, desired stability, and minimal sample handling for the detection, degradation, and removal of hazardous contaminants. In this review, various gold–carbon nanocomposites-based sensors/biosensors that have been developed thus far are explored. The electrochemical platforms, synthesis, diverse applications, and effective monitoring of environmental pollutants are investigated comparatively.
