| Abstract | The conventional impregnation method was used to prepare 15 wt% Mn-supported catalysts, which were applied to the catalytic oxidation of volatile organic compounds (VOCs; toluene, benzene, and o-xylene). The effects of calcination temperatures in the range of 500–900 °C and supports (γ-Al$_{2}$O$_{3}$, SiO$_{2}$, and TiO$_{2}$) on the property and performance of 15 wt% Mn-supported catalysts were investigated. Their physicochemical characteristics were analyzed by the BET, XRD, NH$_{3}$–TPD, H$_{2}$–TPR, and XPS. The calcination temperature greatly affected the crystalline structure and O1s $_{D}$ (defect oxides)/O1s $_{L}$ (lattice oxides) area ratio of the 15 wt% Mn/γ-Al$_{2}$O$_{3}$ (15 Mn/Al) catalyst. The order of the O1s $_{D}$/O1s $_{L}$ area ratios of the 15 Mn/Al catalysts with respect to calcination temperature was 900 > 500 > 700 °C, which was in good agreement with that observed for the catalytic activity. In addition, the activity order of the 15 wt% Mn-supported catalysts with respect to the type of support was γ-Al$_{2}$O$_{3}$ > SiO$_{2}$ > TiO$_{2}$. The 15 wt% Mn/Al catalyst, which had a higher O1s $_{D}$/O1s $_{L}$ area ratio, showed better activity than the 15 wt% Mn/SiO$_{2}$ (15 Mn/Si) and 15 wt% Mn/TiO$_{2}$ (15 Mn/Ti) catalysts. Defect oxides played a significant role in the catalytic oxidation of VOCs. The catalytic activity with respect to the type of VOC decreased in the order of benzene > toluene > o-xylene. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
