Recent Advances in the Catalytic Oxidation of Volatile Organic Compounds: A Review Based on Pollutant Sorts and Sources

“…581,582 The partial oxidation of methanol however, leads to the formation a more toxic pollutant; formaldehyde, which has somewhat limited its application as a fuel additive in the transport sector. 9,583 The low temperature oxidation of methanol is typically a clean and efficient process, 584,585 which has been investigated over a wide range of different catalysts. [586][587][588][589][590][591][592][593][594][595] Numerous reports have indicated that Co3O4 is a highly active catalyst for the oxidation of methanol.…”

Novel Nanostructured Pd/Co-Alumina Materials for the Catalytic Oxidation of Atmospheric Pollutants

“…The CO 2 desorption peaks were assigned to active sites based on the desorption temperature. The active sites that produce the highest peak of CO 2 , in the low-temperature area, are responsible for the higher methanol oxidation activity [ 3 ].…”

“…However, methanol is recently gaining more and more interest as an environmentally friendly fuel for either gasoline or diesel engines, as it is cheap, has a high-octane value, has a large latent heat of vaporization, is sustainable and has good combustion properties (a high oxygen content and a low ratio of carbon/hydrogen, as well as being non-shooting), and it is thus considered a promising alternative [ 1 , 2 ]. Moreover, methanol combustion/utilization in vehicles may decrease the emission of undesired pollutants, including CO, unburned hydrocarbons, particulate matter and nitrogen oxides, emitting, however, other harmful partial oxidation products, such as formaldehyde and unburned methanol vapor [ 3 ].…”

“…Most research groups have mainly focused on active metal oxide components; however, the type of catalytic carrier is also important, as it crucially affects the generation of active sites and, thus, the catalytic efficiency [ 8 ]. Luo et al [ 3 ] investigated the promoter effect of Ce x Zr 1−x O 2 on Al 2 O 3 supports, which led to the development of the best Pd-based catalyst presenting the optimum methanol oxidation with minimum HCHO formation at a low temperature. The promoting effect was attributed to the enhanced interaction between Pd and the modified support resulting in more reducible species.…”
