Figure 6

Relationship between annealing temperature and ligament size of annealed BHPPd materials. Results of nanoporous Pd (annealed at Ar atmosphere) [17], nanoporous Au (annealed at air atmosphere) [18], and nanoporous Ag (annealed at Ar atmosphere and vacuum) [19] were also shown for comparison.
