Abstract Selective catalytic reduction (SCR) with NH3 as a reducing agent is currently most effective NOx removal
technology for coal-fired flue gas. Activated carbon has low denitration activity, and loading metal oxides on
activated carbon can effectively improve the low-temperature denitration activity, which has been a research
hotspot in recent years. This article mainly summarized the performance of low-temperature denitration of metal
oxides supported on activated carbon, the advantages and disadvantages of different catalysts, and prospects its
farther development of activated carbon-supported metal oxides used in low-temperature denitration
