In　this　research,　camphorquinone　(CQ)-mediated　one-pot　polyol　methods　to　synthesize　silver　right　bipyramids　and　nanorods　with　high　yields　are　developed.　The　key　strategy　of　these　methods　is　the　use　of　CQ　which　is　first　applied　to　selectively　stabilize　Ag(100)　facets　through　capping.　As　CQ　stabilizes　small-sized　nanocrystals,　including　single-twinned　and　nanorod　struc-tures,　we　successfully　synthesized　silver　right　bipyramids　and　nanorods　as　the　two　dominant　products　in　a　CQ-mediated　polyol　system.　Further　morphology　control　between　silver　nanorods　and　silver　right　bipyramids　is　conducted　through　adjusting　the　poly(vinylpyrrolidone)　(PVP)　concentration　and　reaction　temper-ature,　which　can　improve　the　formation　of　single-twinned　and　fivefold　twinned　particles　through　affecting　the　reduction　kinetics.　Silver　nanorods　with　a　yield　of　87%　are　obtained　under　150　degrees　C　with　a　PVP/CQ/AgNO3　molar　ratio　of　1.2:2:1,　while　silver　right　bipyramids　with　a　yield　of　88%　are　obtained　under　120　degrees　C　with　a　molar　ratio　of　1.6:2:1.
