With the awakening of environmental awareness, the importance of air quality to human
health and the proper functioning of social mechanisms is becoming increasingly prominent …

A series of Sm-doped Co 3 O 4 catalysts for the N 2 O direct catalytic decomposition were
synthesized by the sol–gel method using citric acid as a chelating agent and urea as a …

Two ZrO 2 supports with either monoclinic (m-ZrO 2) or tetragonal (t-ZrO 2) crystal phases
were obtained under hydrothermal reaction conditions. ZrO 2-supported Co 3 O 4 catalysts …

Catalytic total oxidation is an effective procedure to minimize emissions of volatile organic
compounds (VOC) emissions in industrial gases. Catalysts in the form of meshes are …

The Co 3 O 4 modified with 1 wt.% Cs was deposited on α-Al 2 O 3 open-cell foam covered
with different washcoats (MgO, MnO 2, SiO 2, TiO 2), investigated by XRD, Raman …

Abstract Supported Co 3 O 4 and Co 4 MnAlO x mixed oxides were prepared by deposition
on the SiC open-cell foams by wet impregnation and suspension methods and …

This investigation aimed to develop a series of new spinel-oxide catalysts with the general
formula Mn x Co 1− x Co 2 O 4 (0.0≤ x≤ 1.0) and testing their activity towards N 2 O direct …

A series of cobalt spinel materials with identical bulk structures were obtained using various
synthesis methods. Two types of precursors were obtained by precipitation with ammonium …

The production of nitric acid is one of the main industrial sources of nitrous oxide entering
the atmosphere, which is an ozone-depleting gas with a potential 310 times higher than that …

In this paper, a series of rare earth (Gd, La, Nd, and Y) doped CuO catalysts have been
successfully prepared by using the microwave assisted co-precipitation method and tested …
