“…For example, wood, 5,6 bamboo, 7 egg shell membrane, 8 sponges, 9 and cotton, 10 which possess complex and hierarchically built anatomies owing to their long‐term genetic evolution and optimization, have been selected as templates to produce various advanced biomorphic ceramics. Orthorhombic α‐MoO 3 has been used in numerous industrial applications due to its unique catalytic and electrochromic properties 11–15 . Recently, some low‐dimensional and porous molybdenum oxide products 16 such as molybdenum oxide fibers, 17 hollow MoO 3 nanospheres, 18 and mesostructured molybdenum oxide toroids 19 have been fabricated using organic biotemplate techniques.…”
