The　MnO2/LaMnO3　catalyst　with　the　rod-like　morphology　obtained　by　alkaline　hydrothermal　and　acid　etching　treatment,　performing　90%　toluene　conversion　at　236　degrees　C　with　a　weight　hourly　space　velocity　of　60　000　mL.g(-l).h(-1).　The　alkaline　hydrothermal　strategy　could　modulate　the　morphology　of　LaMnO3　from　block-like　to　rod-like,　and　A　sites　(La　cations)　were　selectively　dissolved　upon　subsequent　acid　etching　treatment,　constructing　an　enhanced　porous　structure.　Compared　with　the　bulk　LaMnO3　perovskite,　the　MnO2/LaMnO3　catalyst　possesses　the　increased　ratio　of　Mn4+/Mn3+　on　the　surface,　significantly　improving　the　low-temperature　catalytic　activity　and　exhibiting　a　low　apparent　activation　energy　(E-a)　of　38.6　kJ.mol(-1).　Moreover,　the　outcomes　of　XPS　and　O-2-TPD　display　that　the　active　surface　oxygen　species　with　the　higher　concentrations　of　lattice　oxygen　and　increased　surface　oxygen　vacancy　density　were　endowed　after　alkali-acid　treatments,　accelerating　the　adsorption　and　reaction　of　toluene.　This　work　develops　a　promising　strategy　to　design　MnO2/LaMnO3　catalysts　with　enhanced　low-temperature　activity　for　the　removal　of　volatile　organic　compounds　via　high-efficient　and　low-cost　treatment　processes.
