Black Titania with Nanoscale Helicity
Source abstract
Abstract
Abstract The fabrication of mesoporous black titanium dioxide (TiO2−x ) with a chiral nematic organization of core–shell nanorods is reported. Chiral templating of TiO2 nanoparticles onto gelatin‐functionalized cellulose nanocrystals (CNCs) followed by calcination yields carbonized TiO2/CNC helical materials that recover white TiO2 replicas after carbon removal. The hydrothermal surface reduction of the traditional white TiO2 by ascorbic acid affords freestanding chiral nematic black TiO2−x. The black TiO2−x is a visible light active semiconducting mesoporous structure constructed by chiral nematic crystalline–amorphous TiO2 core–shell nanorods. The chiral black TiO2−x nanoparticles supported on mesoporous nanocarbon networks are evaluated as lithium‐ion battery anode electrodes. Beyond the current efforts, these black TiO2−x materials and their composites may be useful in the fields of energy storage and catalysis.
