These nanostructured films constitute of 1 to 5 In- and Zn-based oxide nanocrystalline phases including In2O3(ZnO)3 with superlattice structure and ZnO with rather unexpected rocksalt structure. The octahedral coordination of Zn atoms and practically the same Zn–O distances as in the case of In2O3 facilitate a growth of ZnO rock salt on the surface of In2O3 nanocrystals. The modified Williamson-Hall method is applied to determine the crystallite size and micro-strain in the predominant In2O3 phase. The monotonous crystallite fineness of this phase with increase of Zn content and monotonous increase of In–Zn-based oxide crystallites is established. A mutual doping of In2O3 and ZnO nanocrystallites, leading to the formation of n–n+ contacts at their boundaries, has been revealed. Model representations about the influence of the nanocomposite structure of films on their electrical properties are proposed.","PeriodicalId":731,"journal":{"name":"Physics of the Solid State","volume":"66 2","pages":"31 - 37"},"PeriodicalIF":0.9,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141147520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Industrialization’s discharge of organic and metal ion waste into water systems has created a critical demand for efficient removal and degradation of organic waste. Due to their superior optical and electrical properties, semiconductors like metal oxides and mixed metal oxides have attracted a lot of attention for photocatalysis. The majority of these semiconductors, however, lack the ideal band alignment necessary for effective sun/solar light absorption. FeVO4 can be a useful tool for band tuning for visible light photocatalysis in order to get around this problem. Many attempts have been made over the years to increase FeVO4’s photocatalytic performance. It has been postulated and put into practice that a number of different modification strategies, including element doping and composite fabrication, can be utilized to increase the efficiency of photocatalysts based on FeVO4. The photocatalytic degradation of harmful organic pollutants by various metal- and non-metal-doped FeVO4-based materials is highlighted in this review paper. In recent years, significant progress has been made in understanding the core problems and creating effective photocatalysts.","PeriodicalId":731,"journal":{"name":"Physics of the Solid State","volume":"66 1","pages":"15 - 19"},"PeriodicalIF":0.9,"publicationDate":"2024-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140934959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A possible strategy to enhance its structural and optoelectronic properties is element doping. In this work, we report on the successful preparation of α-Fe2O3 nanorods thin film via a simple low-cost hydrothermal process, and the crucial effect of yttrium doping. We analyzed the effects of Y-doping of α-Fe2O3 by varying the amount of yttrium 1, 3, 5, and 8 at %. The optical study revealed that Y-doping reduces the optical band gap, with a shift from 2.11 eV for pure hematite NRs films to 1.94 eV for 5 at % Y-doped NRs. Our study proved that Y-doping obviously reduced the recombination activities in α-Fe2O3 as demonstrated by the photoluminescence study. Amongst all doped α-Fe2O3 NRs films with different Y dopant concentration, the 5 at % exhibited best structural and optoelectronic properties with the highest photocurrent density and incident photon to current efficiency (IPCE). The photocurrent density was increased from 0.25 (undoped) to 1.25 mA/cm2 in the doped NRs with 5 at % Y content at 0.4 V vs. (Ag/AgCl) under illumination, which is 5 times higher than that measured in the pristine α-Fe2O3. The high photo-response of Y-doped NRs in the visible range suggests that the grown NRs thin films are excellent candidates for optoelectronic applications, particularly in solar cells and large light-harvesting devices.","PeriodicalId":731,"journal":{"name":"Physics of the Solid State","volume":"66 1","pages":"1 - 9"},"PeriodicalIF":0.9,"publicationDate":"2024-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140934952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the next step, the photocatalytic activity of the prepared photocatalysts for the removal of toxic dyes under visible light has been investigated. For this purpose, toxic dyes have been removed in the presence of photocatalyst and visible light under specific experimental conditions. It was found that under visible light, longer time is required, but under UV analysis, they degrade within 60 min. Then, using techniques such as UV electron absorption spectroscopy, the extent of dye removal has been measured. The results show that the magnetic nanocomposite photocatalysts based on carbon nanotubes, coated with cobalt ferrite and zinc oxide have high photocatalytic activity for the removal of toxic dyes under visible light. Also, the results show that coating the carbon nanotube with cobalt ferrite has a significant improvement in photocatalytic activity and increasing the amount of cobalt ferrite shows a substantial perfection in the removal of toxic dyes. Also, the magnetic nature of the prepared photocatalysts allows their easy recovery after use.","PeriodicalId":731,"journal":{"name":"Physics of the Solid State","volume":"65 2-6","pages":"131 - 136"},"PeriodicalIF":0.9,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140569805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
