Ordered　meso/macroporous　metal　oxides　have　gained　increasing　attention　in　heterogeneous　catalysis　arising　from　their　large　surface　areas　and　pore　volumes,　elevated　catalytic　activity　and　good　thermal　stability.　Compared　to　nonporous　metal　oxides,　their　most　prominent　feature　is　the　ability　to　interact　with　molecules　not　only　at　their　exterior　surface　but　also　within　the　large　interior　surface　of　the　material.　The　past　decade　has　witnessed　substantial　advances　in　the　synthesis　of　new　porous　metal　oxides　with　ordered　structures　for　use　in　a　wide　range　of　applications.　By　recalling　some　of　the　classical　fundamentals　of　porous　materials,　this　review　examines　the　recent　developments　in　ordered　meso-and　macro-porous　metal　oxide　catalysts　for　heterogeneous　catalysis.　Additionally,　we　outline　the　current　challenges　in　the　field　of　nanoparticle-based　catalysis,　including　the　role　played　by　the　morphology　(size,　shape,　and　porosity)　of　ordered　meso/macroporous　metal　oxides,　and　provide　a　perspective　on　the　need　for　further　advances　in　porous　materials　so　that　their　contribution　to　heterogeneous　catalysis　can　continue　to　expand.
