It is well known that urbanization and industrialization have resulted in the rapidly increasing
emissions of volatile organic compounds (VOCs), which are a major contributor to the …

Emission of volatile organic compounds (VOCs) is one of the major contributors to air
pollution. The main sources of VOCs are petroleum refineries, fuel combustions, chemical …

Three-dimensional (3D) hierarchical Co3O4 nanocatalysts with different morphologies and
various exposed crystal planes were synthesized via a hydrothermal process without the …

Volatile organic compounds (VOCs) emitted from various industrial processes are extremely
harmful pollutants. They are involved in the formation of ozone, photochemical smog, and …

Co3O4 spinel has been widely investigated as a promising catalyst for the oxidation of
volatile organic compounds (VOCs). However, the roles of tetrahedrally coordinated Co2+ …

Great progress has been made in the preparation and application of ordered mesoporous
metal oxides during the past decade. However, the applications of these novel and …

For the transition metal oxide based VOCs oxidation catalysts, both the activity and thermal
stability have to be further improved. In this work, we report the synthesis of oxygen vacancy …

Spent lithium-ion batteries (LIBs) usually containing transition metals (eg, nickel, cobalt,
manganese) and toxic organic electrolytes can negatively affect the human health and …

Among the possible substitutes for noble metals, cobalt-based catalysts represent promising
alternative systems. In recent years, many articles have been devoted to the synthesis …

The cobalt oxides and manganese oxides have high-activity potential for catalytic oxidation
of volatile organic compounds (VOCs), while the mesoporous hollow morphology is crucial …
