In this study, polypyrrole-based activated carbon was prepared by the carbonization of polypyrrole at 650 °C for 2 h in presence four-times mass KOH as a chemical activator. The structural and morphological properties product (polypyrrole-based (PPyAC4)), analyzed scanning electron microscopy, transmission X-ray diffraction, thermogravimetric analysis, support its applicability an adsorbent. adsorption characteristics PPyAC4 were examined through lead ions from aqueous solutions. influence...
Abstract Herein, a facile green synthesis route was reported for the of Ag–ZnO nanocomposites using potato residue by simple and cost effective combustion investigated photocatalytic degradation methylene blue (MB) dye. In preparation extract functioned as biogenic reducing well stabilizing agent reduction Ag + , thus eliminating need conventional reducing/stabilizing agents. with different mass fractions ranging from 2 to 10% were characterized XRD, FT-IR, XPS, SEM, TEM, UV–Vis...
Abstract This study addresses the pressing issue of environmental pollution caused by antibiotics and synthetic dyes in aquatic ecosystems, presenting a novel approach for their efficient photocatalytic degradation. Zinc oxide (ZnO)-based nanoscale photocatalysts, including ZnO nanoparticles (NPs) ZnO/Ag nanocomposite heterostructure (NCH), were synthesized through an innovative eco-friendly method utilizing extract derived from discarded lemon peels as biogenic reducing agent. The materials...
In this study, we report the fabrication of graphitic carbon nitride doped zinc oxide nanocomposites, g-C3N4/ZnO, (Zn-Us) by using different amount urea. They were further characterized X-ray Diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), Raman, UV-vis, Scanning electron microscopy (SEM), and Transmission (TEM) techniques. The prepared nanocomposites used as photocatalysts for mineralization light sensitive dyes Methylene Blue (MB) Rose Bengal (RB) under UV irradiation,...
The construction of a UV-Vis and direct sunlight functioning photocatalyst is puzzling task for organic pollutant removal. Herein, we have fabricated Gd/N co-doped ZnO nanoparticles the first-time using simple co-precipitation method photocatalytic degradation application. heteroatom doping enhances light absorption ability acts as photo-induced electron-hole separator by creating trap state. Co-doped shows comparatively high efficiency about 87% 93% under solar respectively. Moreover,...
Interface-induced nonradiative recombination losses at the perovskite/electron transport layer (ETL) are an impediment to improving efficiency and stability of inverted (p-i-n) perovskite solar cells (PSCs). Tridecafluorohexane-1-sulfonic acid potassium (TFHSP) is employed as a multifunctional dipole molecule modify surface. The solid coordination hydrogen bonding efficiently passivate surface defects, thereby reducing recombination. induced positive between ETLs improves energy band...
The adsorption of methyl orange (MO) from aqueous solutions onto a KOH-activated polypyrrole-based adsorbent (PACK) was investigated using batch and fixed-bed column techniques. structural, thermal, morphological properties the PACK, analyzed by various methods, support its applicability as an adsorbent. An kinetic study revealed preferably pseudo-second-order (R2 = 0.9996) rate-limiting step controlled both film intra-particle diffusions. thermodynamic tests resulted in negative ΔG°, ΔH°,...
