“…[92] Inspired by this structural feature, Zhang and co-workers prepared Au/TiO 2 nanocomposites through sol-gel technique in ethanol/water medium, followed by deposition-precipitation process, using butterfly wings as the template. [93] Compared with original template butterfly wings, the replica preserved the complicated reticular structure, which exhibited a cavity diameters comparable with the wavelength of visible light about 400-800 nm (Figure 7d,e). The synthesized biomorphic Au/TiO 2 with gold to titanium of 8 wt% shows almost 2 times improved photocatalytic activity on methyl orange degradation than pure TiO 2 particles.…”

The conversion of solar energy to sustainable energy sources is a significant field of study for the relief of the world's energy problems, and among the various strategies developed, semiconductor photocatalysts have received significant attention as a promising candidate due to their attractive efficiency, mild reaction conditions, and low cost. The enhancement of such photocatalysts with plasmonic materials, by virtue of the Schottky junction and localized surface plasma resonance phenomenon, could facilitate the rapid progress in enhancement of photocatalytic efficiency under visible light irradiation. To further improve photocatalytic efficiency, scientists look to nature for inspiration, culminating in the evolution of complex hierarchical structures in order to fully utilize the potential of solar energy. In the past decade, there has been significant progress in the development of bio‐inspired plasmonic photocatalysts, such as antireflective surfaces, 3D photonic structures, and branched structures. This review describes the state‐of‐the‐art bio‐inspired light manipulation approaches, as well as future challenges in solar energy harvesting by plasmonic photocatalysts.

“…14,15 Fortunately, nature might offer some inspiration for creating functional structures and components for desired properties. 20,21 Especially for Euploea mulciber butterfly wings, their well-organized hierarchical architecture should have an advantage of gas sensing applications. In previous research, some biomatters such as eggshell membranes, 16 pollen grains, 17 diatoms, 18 and butterfly wings 19 were introduced as templates to synthesize various sulfides, oxides, and metal nanomaterials with special hierarchical architectures for related valuable properties.…”

PdO‐decorated SnO2 nanocomposites with open porous hierarchical architectures are fabricated through a facile biotemplating sol–gel technique. The sol–gel soakage process is carried out by immersing the templates butterfly wings in Sn‐ and Pd‐ impregnants successively to generate a uniform colloid layer. PdO and SnO2 nanocrystallites come into being with subsequent calcination treatment, and PdO‐decorated SnO2 nanocomposites further construct the parallel main ridges with connective pillars and vertical struts, finally present a 3‐D open porous hierarchical architecture. Benefiting from unique ingredients and structure hierarchy, the nanocomposites give enhanced acetone‐sensing performance of high sensitivity and rapid response/recovery rate
