Photocatalysis with modified titania is a promising approach to improve both air and health quality. Modified novel photocatalytic properties under indoor light irradiation leads smart coatings, which are benchmark materials suitable for their applications. It generally accepted that the activity affected by absorption, charge creation/recombination rate surface reactivity. In this contribution we focus on TiO2 as catalyst in heterogeneous photo-catalytic processes address efficiency of...
Hybrid lead halide spin coated perovskite films have been successfully tested as portable, flexible, operated at room temperature, self-powered, and ultrasensitive ozone sensing elements. The electrical resistance of the hybrid mixed (CH3NH3PbI3-xClx) element, was immediately decreased when exposed to an (O3) environment manage recover its pristine conductivity values within few seconds after complete removal gas. measurements showed different response times gas concentrations, good...
Hydrogen production through photocatalytic water reduction, a potential path for future renewable and sustainable energy generation.
Herein, the physicochemical properties and enhanced adsorption capacity of highly porous thin-layer graphitic carbon nitride (g-C3N4) nanosheets (CNNs) in relation to separation dyes are investigated. Cationic anionic with similar sizes adopted study nitride. Highly g-C3N4 were synthesized via direct thermal polycondensation melamine followed by a exfoliation. A comparative bulk thin-film was carried out. The results revealed formation well-oriented structure adequate chemical stability....
Abstract High‐entropy alloys (HEAs) have attracted significant attention for electrocatalytic energy conversion by virtue of their promisingly high efficiency, stability, and low cost. Recently, encouraging progress has been made in tuning the structure composition HEAs used electrolyzers fuel cells. However, understanding on synthetic methods structure‐property‐performance relationship well‐defined nanostructures is still inadequate. To gain insight into future research directions...
Abstract Metal halide perovskites (MHPs) have attracted significant attention owing to their simple manufacturing process and unique optoelectronic properties. Their reversible electrical or optical property changes in response oxidizing reducing environments make them prospective materials for gas detection technologies. Despite advancements perovskite‐based sensor research, the mechanisms behind perovskite‐gas interactions, vital performance, are still inconclusive. This work presents...
Ordinary textiles are very often malodorous and the origin of cross-infection. Their microclimate, consisting moisture, contaminants, sweat, provides favorable conditions for microbial growth. Therefore, simple approaches surface modification using functional materials widely adopted to introduce antibacterial properties. This study reports a low cost technique that renders cotton fabrics antibacterial. Manganese (Mn)-doped photocatalytic titanium dioxide (TiO2) nanoparticles ∼150 nm average...
The photocatalytic oxidation of gaseous benzene, toluene and xylene (BTX) over un-doped, 0.1 1 wt% Mn-TiO2 nanoparticles under ultraviolet visible irradiation was studied in atmosphere synthetic air or inert gas. decomposition efficiency the products were determined using a Static Photochemical Reactor coupled with FTIR spectroscopy. BTX underwent efficient photocatalysts UV irradiation, more oxygen presence less without oxygen. More important went substantial mol% presence. main final...
Ligand-free all-inorganic lead halide nanocubes have been investigated as ozone sensing materials operating at room temperature. It is found that the nanocubes, crystallined in orthorhombic CsPbBr3 structure, can operate temperature, be self-powered and exhibit high sensitivity remarkable repeatability. More importantly, they demonstrate higher (54% 187 ppb) faster response recovery times compared to hybrid mixed perovskite (CH3NH3PbI3-x Cl x ) layers, which only material tested for sensing,...
