Flexible Transparent Molybdenum Trioxide Nanopaper for Energy Storage

A flexible transparent molybdenum trioxide nanopaper, assembled via ultralong molybdenum trioxide nanobelts, displays an excellent average transmittance of ≈90% in the visible region. The free-standing nanopaper electrode delivers an outstanding specific capacitance of 1198 F g−1 and shows an excellent long-term stability performance over 20 000 cycles with a retention rate of 99.1%.
