Modulating the Midgap States of 3D–2D Hybrid ZnO by Codoping and Its Effect on Visible Photocatalysis

“…RhB is an organic dye widely used in textile and food industries for various purposes, which pollutes water and induces carcinogenic activity upon consumption . Therefore, it is important to reduce the pollution level by various means and photocatalysis is one of them. , Motivated by the absorption of light in the visible region, we have exploited the applicability of the mid-energy level-engineered ZnO in visible light-driven catalysis and aimed to understand the role of various parameters in the desired process. Figure S5 represents the schematic of the experimental setup for the photocatalytic experiment.…”

Rubber Tiles Made from Secondary Raw Materials with Immobilized Titanium Dioxide as Passive Air Protection

“…), future research will be directed toward the actual performance computation of reported materials. For instance, the reduction of CO2 to CO was analyzed by using performance metrics such as quantum yield (QY), space-time yield (STY), figure of merits (FoM), turnover frequency (TOF), and turnover number (TON) [41][42][43][44][45]. This will be an initial point for a further in-depth analysis of NH3 reduction toward N2.…”

TiO2-based catalytic systems for the treatment of airborne aromatic hydrocarbons

“…151 Other key performance metrics, such as the quantum yield (QY: molecules photon À1 ; eqn ( 19)), the space-time yield (STY: molecules photon À1 mg À1 ; eqn (20)), and the figure of merit (FOM: L mg À1 mol À1 J À1 ; eqn (21)), were also used and computed to offer a more impartial assessment of the actual performance of the reported photothermocatalysts tested under varying experimental conditions. 27,65 Under the assumption that all irradiated photons are absorbed by the photocatalyst, the QY value can be used to express the ratio between the number of oxidized VOC molecules to the number of photons absorbed or emitted (i.e., light irradiance) during the photocatalytic oxidation process. 152,153 Considering the significant effect of photocatalyst amount on the catalytic reaction, the STY (a comparable metric to the turnover frequency (TOF) values) was also calculated by normalizing the QY value with the amount of catalyst used in the reaction system to assess the number of oxidized VOC molecules over each catalytic This journal is © The Royal Society of Chemistry 2023 site irradiated by the targeted light source.…”

“…23,24 Consequently, photocatalytic abatement of BTX has attracted increasing attention because of its cost-effectiveness and ability to work in ambient conditions. [25][26][27] However, the feasibility of photocatalysis is often limited by frequent deactivation of photocatalysts, poor light This journal is © The Royal Society of Chemistry 2023 harvesting, and energy demands (i.e., photon efficiency). 28,29 In light of such shortcomings, photothermocatalytic treatment techniques driven by light as an energy source have often been suggested as potent alternatives for the control of air pollutant emission.…”
