Özet

Morphology controlled synthesis of nanomaterials by tuning simple preparative parameters is an impressive path to develop diverse nanostructured materials. The SILAR technique is used to evaluate the manufacturing samples of MoO3, TiO2, and MoTiO5 nanostructures. These nanostructures of MoO3, TiO2, and MoTiO5 are used as electrode materials in photovoltaic systems. The link between photoelectrochemical characteristics and MoO3, TiO2, and MoTiO5 nanostructures is studied in depth. The photoelectrochemical characteristics of MoO3, TiO2, and MoTiO5 nanostructures are discovered to be highly dependent. At a 5 mV/s scan rate, the photocurrent of MoO3, TiO2, and MoTiO5 electrodes surged fast when sunlight was turned on, reaching values of 1.03 mA cm-2, 1.68 mA cm-2, and 14.20 mA cm-2, respectively. As soon as the sunshine was turned off, the photocurrent value dropped to zero. The photocurrent transients had quick and homogeneous photocurrent responses, suggesting that charge transport in these materials is rapid and may be linked to the crystalline structures of MoO3, TiO2, and MoTiO5. MoTiO5 nano-belt and nano-disc thin films have typical uses in the photoelectrochemical sector because they have the best photoresponse and stability.
