“…The reflected Raman peaks were at 142, 246, 298, and 373 cm –1 for NiS; 346, 462, 487, and 557 cm –1 for NiS 2 ; and 185, 280, and 633 cm –1 for Ni 3 S 2 . 21,26−38 A single Raman scattering peak was reflected in NiF due to its metallic character (Figure 3B,a). The presence of numerous peaks in the broad range of 900–1200 cm –1 indicated the existence of sulfate (S 2– ) ions.…”

We report water-splitting application of chemically stable self-grown nickel sulfide (Ni x S y ) electrocatalysts of different nanostructures including rods, flakes, buds, petals, etc., synthesized by a hydrothermal method on a three-dimensional Ni foam (NiF) in the presence of different sulfur-ion precursors, e.g., thioacetamide, sodium thiosulfate, thiourea, and sodium sulfide. The S 2– ions are produced after decomposition from respective sulfur precursors, which, in general, react with oxidized Ni 2+ ions from the NiF at optimized temperatures and pressures, forming the Ni x S y superstructures. These Ni x S y electrocatalysts are initially screened for their structure, morphology, phase purity, porosity, and binding energy by means of various sophisticated instrumentation technologies. The as-obtained Ni x S y electrocatalyst from sodium thiosulfate endows an overpotential of 200 mV. The oxygen evolution overpotential results of Ni x S y electrocatalysts are comparable or superior to those reported previously for other self-grown Ni x S y superstructure morphologies.

“…Provided that a counter electrode exhibits a capacitive property of an electrical double-layer capacitor 44 , the capacitance value should related to the surface area of counter electrode. That is, a large electrochemical capacitance value of the electrode should relate to a large specific surface area, which is a crucial factor for high electrocatalytic activities 45 46 47 . In this study, an MPC electrode had a higher active surface area than that of sputtered Pt because its capacitance value was larger than Pt’s.…”

Mangosteen peel is an inedible portion of a fruit. We are interested in using these residues as components of a dye sensitized solar cell (DSSC). Carbonized mangosteen peel was used with mangosteen peel dye as a natural counter electrode and a natural photosensitizer, respectively. A distinctive mesoporous honeycomb-like carbon structure with a rough nanoscale surface was found in carbonized mangosteen peels. The efficiency of a dye sensitized solar cell using carbonized mangosteen peel was compared to that of DSSCs with Pt and PEDOT-PSS counter electrodes. The highest solar conversion efficiency (2.63%) was obtained when using carbonized mangosteen peel and an organic disulfide/thiolate (T2/T−) electrolyte.

“…A pronounced 3.59% improvement in performance, close to that of a Pt DSSC (3.84%), was achieved by compositing TiC with carbon as the catalyst (Towannang et al, 2012). Furthermore, a combination of chemical bath deposition, an arc evaporation process, and annealing was used to synthesize a bilayered carbon-decorated Ni 3 S 2 composite nanowall film as a cocatalyst (Maiaugree et al, 2015b). The large surface area of the nanostructure and its high electrocatalytic activity improved the efficiency of a pure evaporated-carbon DSSC.…”

Dye-sensitized solar cells (DSSCs) have been developed as a promising photovoltaic cell type in recent decades because of their low cost, environmental friendliness, ease of fabrication, and suitability for a wide range of indoor and outdoor applications, especially under diverse shaded and low-light condition. They are typically composed of three main components: a transparent conducting oxide (TCO) substrate-based working electrode with wide-bandgap semiconductors and dye sensitizer molecules, an electrolytic mediator based on redox couple species, and a TCO-based counter electrode consisting of catalyst materials. The development of intrinsic and functional organic, inorganic, metal oxide, composite, and carbon-based materials has been intensively studied to enhance the efficiency of DSSCs. A simple and low-cost fabrication process that uses natural products is also considered essential for further large-scale production. In this article, we review the fabrication of various functional materials and their effects on DSSC performance.
