Direct Z-scheme La1-xCexMnO3 catalyst for photothermal degradation of toluene
Environmental Science and Pollution Research, 2019A series of Ce-doped LaMnO3 (La1-xCexMnO3) were prepared and were tested for gaseous toluene oxidation in order to investigate the effect of cerium doping in LaMnO3 on activity under photothermal conditions. It was found that the activity and CO2 yield of the catalyst can be effectively increased when x = 0.25.

Analytica Chimica Acta, 2020
Advanced oxidation processes (AOPs) have recently proposed for advancing colorimetric sensing applications, owing to their excellent performance of sensitive color readout that generated from the oxidation of chromogenic substrates like 3,3',5,5'-tetramethylbenzidine (TMB) by reactive oxygen species (ROS) of AOPs such as ·OH and ·O2- radicals. However,

Infrared Photothermal Deflection Spectroscopy of Carbon-Supported Metal Catalysts
Spectroscopy Letters, 1982Abstract The infrared (IR) study of surface species and reactions occurring on solids has contributed markedly to our understanding of surface chemistry and heterogeneous catalysis, and a wide variety of solids has been examined. However, an entire class of catalysts consisting of metal dispersed on carbon has never been studied because the carbon ...

Study on the preparation of photothermal catalyst for toluene degradation from spent batteries
Separation and Purification TechnologyThis work produced a novel photothermal catalyst TiO2-CeO2@S-AZMB for toluene degradation, based on waste zinc-manganese batteries. Using a direct ball milling technique, the catalyst was created by mixing nanoscale TiO2 and CeO2 with active metals extracted from wasted batteries.
