The effect of different crystal phases, i.e. spinel phase (CuMn2O4) and amorphous phase (Cu0.2MnOx), was explored in Cu-Mn catalytic ozonation of toluene. The toluene removal efficiency followed the order of Cu0.2MnOx (91.2%) > CuMn2O4 (74.5%) > commercial catalyst Cu0.3MnOx (70.3%) in 130 min, and the higher CO2 yield (67.6%) could be also observe...
The abatement of toluene was studied in a sequential adsorption-plasma catalysis (APC) process. Within this process, Hopcalite was used as bifunctional material: as adsorbent (storage stage) and as catalyst via the oxidation of adsorbed toluene (discharge stage). It was observed that the desorption and oxidation activity of the adsorbed toluene was...
Herein, the effects of different crystalline phases of TiO2 on the adsorption-plasma photocatalytic oxidation of toluene were investigated. First, photocatalysts loaded on a molecular sieve (MS) were characterised and the catalytic performance of toluene abatement was evaluated in a plasma system. The COx yield of the pure anatase (An) sample outpe...
A dielectric barrier discharge reactor packed with both Hopcalite & glass beads has been investigated for the total oxidation of toluene adsorbed on Hopcalite. The catalytic activity and selectivity through the possible formation of by-products during the NTP discharge for the abatement of irreversibly adsorbed toluene have been investi- gated by F...
It is of great significance to explore and develop in-situ preparation strategies to improve the activity and service life of monolithic catalysts. In this work, the strategy of alternating anode and cathode electro-deposition was creatively proposed, a hierarchical monolithic catalyst that three-dimensional nickel foam with an open-pore structure ...

In this work, three-dimensional mesoporous MnO2, K/MnO2, Pt/MnO2 and K-Pt/MnO2 catalysts were prepared through hard-template method. The additional K/Pt had significantly improved the HCHO oxidation activity. The K-Pt/MnO2 catalyzed complete HCHO oxidation was achieved at 0 degrees C with space velocity (GHSV) at 50000 ml/(g.h). With the excellent ...
In this study, the thermal stability of a Fe2O3 catalyst for mercury oxidation was significantly improved by doping with Al2O3. After 1 hr, the catalyst doped with 10 wt.% Al2O3 still exhibited a mercury conversion efficiency of 70.9%, while the undoped sample even lost its catalytic activity. Doping with Al2O3 retarded the collapse of the catalyst...
