Research　progress　including　our　own　work　in　preparation　and　application　of　mu-oxo-bismetallotetraphenylporphyrin　biomimetic　catalysts　is　reviewed.　All　synthetic　methods　of　the　mu-oxo-bismetallotetraphenylporphyrins　are　comprehensively　discussed,　involving　the　two-step　method,　the　chromatographic　column　method,　the　one-step　method,　the　auto-oxidation　method　and　the　one-pot　method　developed　by　our　group.　Although　the　yield　of　the　mu-oxo-bismetallotetraphenylporphyrin　compounds　by　using　the　one-pot　method　has　been　not　high　enough　now,　potentially　it　would　become　a　good　method　for　synthesis　in　the　future　due　to　the　simple　steps　and　no　need　of　purification　of　intermediate　products.　Some　applications　of　the　mu-oxo-bismetallotetraphenylporphyrins　as　biomimetic　catalysts　are　elaborated　upon.　Further　investigations　will　be　focused　on　the　oxidation　of　hydrocarbons　to　products　containing　oxygen　by　using　the　mu-oxo-bismetallotetraphenylporphyrins　as　catalysts　because　of　their　advantages　and　features　such　as　using　smaller　dosage　rates　of　the　catalysts,　a　cheaper　and　cleaner　oxidant　O-2,　and　neither　co-catalysts　nor　co-reductants　as　well　as　milder　reaction　conditions.
