The invention provides an SCR (Selective Catalytic Reduction) denitration catalyst as well as a preparation method and application thereof. The catalyst comprises the following main components: titanium dioxide, ferric vanadate, vanadium pentoxide, cerium oxide, ferric oxide and glass fiber. The method comprises the following steps: preparing an active component solution, preparing carrier mixed powder, preparing a catalyst precursor material block, aging, forming, drying and calcining. The catalyst can be used for catalyzing the denitration reaction of industrial tail gas. According to the SCR denitration catalyst, the active components are designed on the basis of a traditional vanadium-tungsten-titanium catalyst system, the forming process and the formula are correspondingly improved, novel active components with complexed vanadium and iron are formed, the active components are dispersed more uniformly, microcosmic pore channels are more developed, the strength is improved, forming is reliable, and the SCR
