Photothermal Synergistic Effect of Pt₁/CuO-CeO₂ Single-Atom Catalysts Significantly Improving Toluene Removal

Environmental Science & Technology, Год журнала: 2022, Номер 56(12), С. 8722 - 8732

Опубликована: Май 17, 2022

Photothermal synergistic catalytic oxidation of toluene over single-atom Pt catalysts was investigated. Compared with the conventional thermocatalytic in dark, conversion and CO2 yield 0.39Pt1/CuO-CeO2 under simulated solar irradiation (λ = 320-2500 nm, optical power density 200 mW cm-2) at 180 °C could be increased about 48%. An amount CuO added to CeO2 disperse a maximal loading 0.83 wt %. The effect between photo- thermocatalysis is very important for development new pollutant treatment technology high efficiency low energy consumption. Both light heat played an role present photothermal oxidation. showed good redox performance excellent properties utilized full-spectrum energy. Light illumination induced generation reactive oxygen species (•OH •O2-), which accelerated transformation intermediates, promoted release active sites on catalyst surface, improved reaction.

Modulating the Electronic Metal‐Support Interactions in Single‐Atom Pt₁−CuO Catalyst for Boosting Acetone Oxidation

Angewandte Chemie International Edition, Год журнала: 2022, Номер 61(28)

Опубликована: Март 29, 2022

The development of highly active single-atom catalysts (SACs) and identifying their intrinsic sites in oxidizing industrial hazardous hydrocarbons are challenging prospects. Tuning the electronic metal-support interactions (EMSIs) is valid for modulating catalytic performance SACs. We propose that modulation EMSIs a Pt1 -CuO SAC significantly promotes activity catalyst acetone oxidation. promote charge redistribution through unified Pt-O-Cu moieties, which modulates d-band structure atomic Pt sites, strengthens adsorption activation reactants. positively charged atoms superior activating at low temperatures, stretched Cu-O bonds facilitate lattice oxygen to participate subsequent believe this work will guide researchers engineer efficient SACs application hydrocarbon oxidation reactions.

Photocatalytic Oxidation for Volatile Organic Compounds Elimination: From Fundamental Research to Practical Applications

Environmental Science & Technology, Год журнала: 2022, Номер 56(23), С. 16582 - 16601

Опубликована: Ноя. 11, 2022

Photocatalysis is regarded as one of the most promising technologies for indoor volatile organic compounds (VOCs) elimination due to its low cost, safe operation, energy efficiency, and high mineralization efficiency under ambient conditions. However, practical applications this technology are limited, despite considerable research efforts in recent decades. Until now, works were carried out laboratory focused on exploring new catalytic materials. Only a few involved immobilization catalysts design reactors applications. Therefore, review systematically summarizes development photocatalytic oxidation (PCO) VOCs, with emphasis catalyst's reactor designs detail. First, different types materials mechanisms PCO VOCs briefly discussed. Then, both techniques reviewed Finally, existing challenges future perspectives proposed. This work aims provide updated information inspirations commercialization future.
