The physical properties of MB layer were evaluated using optical, structural and morphological studies. The MB layer shows strong optical absorption at 308 nm and 601 nm implying an optical bandgap of 3.05 eV and 1.45 eV respectively. The morphology of the MB layer on the Ge substrate shows a very smooth surface with a uniform distribution of grains. The structural property of the MB layer analysed using FTIR measurement indicates various distinguished bonds signify the structure of organic layer. Comprehensive analysis of interfacial parameters, including the ideality factor (n), barrier height (Φb) and series resistance (RS) are extracted for both Au/n-Ge contact and MB/n-Ge heterojunction using current-voltage (I-V) and capacitance-voltage (C-V) approaches. Notably, the heterojunction exhibits a significantly enhanced rectification ratio and very low RS compared to the Au/Ge contact, making MB a promising candidate for Schottky device based photovoltaic cells. The barrier parameters were checked for consistency with other approaches such as Cheung and Norde methods. Additionally, the study also explained the impact of the MB interlayer on the density of interface traps/states (Nss) of Au/n-Ge junction. The photovoltaic properties of the MB/n-Ge heterojunction were analysed under different illumination powers. The photovoltaic cell parameters and the barrier parameters were examined under illumination for different optical power. The fill factor of the heterojunction shows a larger magnitude at 60 mW/cm2.","PeriodicalId":639,"journal":{"name":"Journal of Inorganic and Organometallic Polymers and Materials","volume":"36 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The design and development of effective photoanodes and their materials still play a significant role and can be explored. Metal doping in TiO2 semiconductor has been proven to be an effective way for charge separation. The synthesis of bismuth (Bi) doped TiO2 materials is attempted with different Bi doping quantities through wet impregnation for their utilization in DSSCs. The purpose of the Bi-doped TiO2 synthesis was to develop an efficient photoanode material with an enhanced charge separation capacity to be applied in DSSC, leading to high current density and overall device performance. The morphology and optical behaviour of synthesized materials were characterized by powder X-ray diffractometer (P-XRD), UV-visible spectrophotometry, field emission scanning electron microscopy (FESEM), Fourier-transform infrared spectroscopy (FTIR), photoluminescence (PL), and thermogravimetric analysis (TGA). The synthesized materials were used to prepare absorption layers of photoanode in DSSCs in conjunction with a ruthenium-based dye (N719). The findings showed that the highest power conversion efficiency (PCE) of the Bi-doped TiO2-based DSSCs was measured 5.50% using 3% Bi doping to TiO2 (w/w), surpassing the 3.58% efficiency achieved by the TiO2-based DSSCs in similar conditions, with an enhancement of ~ 54% in PCE performance. The enhanced performance could be attributed to the incorporation of Bi to TiO2 which can help with electron transfer in the forward direction in DSSCs circuit by reducing electron–hole recombination.","PeriodicalId":639,"journal":{"name":"Journal of Inorganic and Organometallic Polymers and Materials","volume":"22 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142210322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The synthesized micromotors were characterized by scanning electron microscopy (SEM) and energy-dispersive X-Ray spectroscopy (EDX) analysis. The dependence of the mobility of the motors on fuel concentration was evaluated. High speeds of 255 μm s− 1 and 128 μm s− 1 at 5% hydrogen peroxide (H2O2) were observed for Fe3O4/Pt and Fe3O4-OH/Pt micromotors, respectively.

In a groundbreaking step, we adorned MIL-100(Cr) with Fe3O4in-situ to explore its ability to degrade Eosin Yellow (EY) through the photo-Fenton process. Our analyses using PXRD and FT-IR revealed no alterations in the fundamental structure of MIL-100(Cr) upon Fe3O4 modification. However, the addition of this metal oxide led to a reduction in MIL-100(Cr)’s BET surface area, volume, and pore diameter. Fascinatingly, our FESEM-EDX studies revealed a uniform distribution of Fe3O4 within the MIL-100(Cr) matrix. Among our synthesized composites, the 20% Fe3O4/MIL-100(Cr) blend exhibited remarkable photo-Fenton activity, achieving an impressive 93.31% EY degradation within 150 min under optimal conditions employing a Hg lamp.

The confirmation of the significant interaction between NiO and Poly(Ani-co-Py) was obtained through FTIR, UV-visible, and PL spectroscopy.

Furthermore, the composites were employed for the development of a p-NP sensor probe. The developed Poly(Ani-Co-Py)/NiO/PEDOT: PSS/GCE sensor probe showed a higher sensitivity (12.658 µA.µM− 1cm− 2 ) over a large linear dynamic range (LDR) from 0.1µM to 80.0 µM (linearity, r2: 0.9917) with a lower detection limit (LOD; 0.075 µM) and limit of quantification (LOQ; 0.22727 µM) in the detection of p-NP by using linear sweep voltammetry (LSV) technique. It has introduced a new path for the detection of environmentally unsafe chemicals using the electrochemical approach.","PeriodicalId":639,"journal":{"name":"Journal of Inorganic and Organometallic Polymers and Materials","volume":"43 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142210369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
