Recently, design and fabrication of platinum free counter electrodes have received enormous attention of the scientific community. In this work, we have fabricated manganese dioxide/reduced graphene oxide (MnO2@Gr) counter electrode based DSSCs. Hydrothermal method was utilized for the synthesis of MnO2@Gr. Further, X‐ray diffraction technique (XRD), scanning electron microscopy (SEM), and energy dispersive X‐ray spectroscopy (XPS) were employed as physiochemical characterization technique. Surface structural investigations showed that MnO2 has rods like surface morphology which are attached with Gr. The fabricated DSSCs demonstrated good open circuit voltage (Voc) and reasonable efficiency of 0.72 V and 5.87 %, respectively.

“…Thus, it is difficult to commercialize Pt-based DSSCs, and it is necessary to discover alternative Pt-free counter electrode materials for DSSCs. In this regard, various transition metal oxides such as nickel oxide [38,39], manganese dioxide [40], tin oxide [41], copper oxide [42], cobalt oxide [43], zinc oxide [44], tungsten oxide [44], and polymers such as polyaniline [45], polypyrrole [46], and polythiophene [47] have been explored as potential Pt-free counter electrode materials. Some of these Pt-free counter electrode materials have shown good photovoltaic performance, but overall, the performance of Pt-free DSSCs needs to be improved.…”

In this work we reported the hydrothermal preparation of molybdenum disulfide (MoS2). The phase purity and crystalline nature of the synthesized MoS2 were examined via the powder X-ray diffraction method. The surface morphological structure of the MoS2 was examined using scanning electron microscopy and transmission electron microscopy. The specific surface area of the MoS2 was calculated using the Brunauer-Emmett-Teller method. The elemental composition and distribution of the Mo and S elements were determined using energy-dispersive X-ray spectroscopy. The oxidation states of the Mo and S elements were studied through employing X-ray photoelectron spectroscopy. In further studies, we modified the active surface area (3 mm) of the glassy carbon (GC) electrode using MoS2 as an electrocatalyst. The MoS2 modified GC electrode (MSGC) was used as an electrochemical sensor for the detection of thiabendazole (TBZ). Linear sweep voltammetry (LSV) was used as the electrochemical sensing technique. The MSGC exhibited good performance in the detection of TBZ. A limit of detection of 0.1 µM with a sensitivity of 7.47 µA/µM.cm2 was obtained for the detection of TBZ using the LSV method. The MSGC also showed good selectivity for the detection of TBZ in the presence of various interfering compounds. The obtained results showed that MoS2 has good electrocatalytic properties. This motivated us to explore the catalytic properties of MoS2 in dye sensitized solar cells (DSSCs). Thus, we have fabricated DSSCs using MoS2 as a platinum-free counter electrode material. The MoS2 counter electrode-based DSSCs showed good power conversion efficiency of more than 5%. We believe that the present work is beneficial for the scientific community, and especially for research surrounding the design and fabrication of catalysts for electrochemical sensing and DSSC applications.

“…For example, chirality-controlled growth of high-quality single-walled CNTs (SWNTs) is essential for the fabrication of nanoscale electronics [ 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. In addition, mass production of moderate-quality CNTs is vital for the development of CNT-based composites, which find applications in energy storage, thermal management, electromagnetic wave shielding, etc [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ].…”

One-Pot Fabrication of Nanocomposites Composed of Carbon Nanotubes and Alumina Powder Using a Rotatable Chemical Vapor Deposition System

et al. 2023

The fabrication of multi-dimensional nanocomposites has been extensively attempted to achieve synergistic performance through the uniform mixing of functional constituents. Herein, we report a one-pot fabrication of nanocomposites composed of carbon nanotubes (CNTs) and Al2O3 powder. Our strategy involves a synthesis of CNTs on the entire Al2O3 surface using a rotatable chemical vapor deposition system (RCVD). Ehylene and ferritin-induced nanoparticles were used as the carbon source and wet catalyst, respectively. The RCVD was composed of a quartz reaction tube, 5.08 cm in diameter and 150 cm in length, with a rotation speed controller. Ferritin dissolved in deionized water was uniformly dispersed on the Al2O3 surface and calcinated to obtain iron nanoparticles. The synthesis temperature, time, and rotation speed of the chamber were the main parameters used to investigate the growth behavior of CNTs. We found that the CNTs can be grown at least around 600 °C, and the number of tubes increases with increasing growth time. A faster rotation of the chamber allows for the uniform growth of CNT by the tip-growth mechanism. Our results are preliminary at present but show that the RCVD process is sufficient for the fabrication of powder-based nanocomposites.
