Developing an efficient material as a counter electrode (CE) with excellent catalytic activity, intrinsic stability, and low cost is essential for the commercial application of dye-sensitized solar cells (DSSCs). Transition metal phosphides have been demonstrated outstanding multifunctional catalysts in broad range energy conversion technologies. Here, we exploited different phases iron phosphide CEs DSSCs I–/I3–-based electrolyte. Solvothermal synthesis using triphenylphosphine precursor...
The electrochemical reduction reaction of the nitrate ion (NO3−), a widespread water pollutant, to valuable ammonia (NH3) is promising approach for environmental remediation and green energy conservation. development high-performance electrocatalysts selectively reduce NO3− wastes into value-added NH3 will open up different route treatment, impose both economic impacts on sustainable synthesis. Transition metal phosphides represent one most earth-abundant catalysts with impressive...
An efficient and stable CuO-TiO2 nanocomposite photocatalyst was synthesized by using the simple molten-salt method. Characterization HR-TEM confirmed existence of both TiO2 CuO in nanocomposite, revealing hexagonal nanoparticles (NPs) with average particles size 23.8 nm. QDs decorated on surface were range 2.2 to 4.6 Photocatalytic experiments for hydrogen (H2) production carried out under an LED (λ = 365 nm) lamp natural solar light.

We report the photoelectrochemical (PEC) performance of textured porous ZnO and CdX-coated films (X = S, Se). Porous were grown with a platelike morphology on F-doped SnO(2) (FTO) substrates. The growth involves two-step procedure. In first step, we electrochemically grew simonkolleite (Zn(5)(OH)(8)Cl(2)·H(2)O) plate films. Annealing at 450 °C results in as-obtained electrodes then used PEC studies. To increase light-harvesting efficiency, sensitized these CdS CdSe quantum dots, using...
Oxygen vacancies (OVs) are one of the most critical factors that enhance electrical and catalytic characteristics metal oxide-based photoelectrodes. In this work, a simple procedure was applied to prepare reduced TiO2 nanotube arrays (NTAs) (TiO2-x) via one-step reduction method using NaBH4. A series characterization techniques were used study structural, optical, electronic properties TiO2-x NTAs. X-ray photoelectron spectroscopy confirmed presence defects in Photoacoustic measurements...
Fluorescence resonance energy transfer (FRET) is investigated with manganese-doped ZnSe nanoparticles (quantum dots) as long fluorescence lifetime donors and spiropyran molecules acceptors. The kinetics of photochemical ring-opening reaction upon UV-illumination exploited to achieve efficient quenching the manganese lifetimes at a low temperature 78 K in methylcyclohexane/isopentane mixture. Modulation acceptor structure from closed open form allows us investigate temporal decrease donor...
Introduction of oxygen vacancies (OVs) has been investigated as a promising way to improve the electrical and catalytic characteristics hematite (α-Fe2O3) based photoelectrode. In this work, we develop novel method for preparing porous Sn-doped α-Fe2O3 (Sn:Fe2O3) thin films with intrinsic OVs. The procedure included spin-coating an iron precursor onto fluorine-doped tin oxide (FTO) substrate, followed by thermal treatment at elevated temperatures. influence Sn dopant on optoelectronic...
Abstract Recently, the mixed‐dimensional (3D/2D or 3D/1D) perovskite solar cells using small organic spacers have attracted interest due to their outstanding long‐term stability. Here, a new type of thiophene‐based cation 2‐(thiophene‐2yl‐)pyridine‐1‐ium iodide (ThPyI), which is used fabricate 3D/1D cells, presented. The ThPyI‐based 1D perovskitoid applied as passivator on top 3D methyl ammonium lead (MAPI) surface‐passivated films added alone into precursor generate bulk‐passivated MAPI....
A catalytic system based on iron phosphide (Fe2P) has exhibited electrocatalytic activity toward N2-reduction reaction in alkaline medium (0.5 mol dm−3 NaOH).

In this study, we report a facile one-step chemical method to synthesize reduced titanium dioxide (TiO2) nanotube arrays (NTAs) with point defects. Treatment NaBH4 introduces oxygen vacancies (OVs) in the TiO2 lattice. Chemical analysis and optical studies indicate that OV density can be significantly increased by changing reduction time treatment, leading higher transmission of NTAs retarded carrier recombination photoelectrochemical process.
