摘要

•High surface area and pore volume of La0.8Sr0.2FeO3 are obtained by nanocasting.•The enhanced porosity is attributed to controlled removal of silica template.•The higher surface to lattice oxygen ratio leads to the higher CO yield.•Nanocast La0.8Sr0.2FeO3 with 10 wt% of residual Si has the highest CO yield.
