“…Nanoscale TiO 2 is one of the most popular photocatalysts . Many chemical methods have been developed for the synthesis of TiO 2 nanoparticles with various morphologies such as NSs, NBPs, hollow nanostructures, and nanosheets . Although the preparation of TiN nanostructures through the nitridation of TiO 2 nanostructures have been reported before, ,− the control of the morphologies and sizes of TiN nanoparticles through the nitridation of TiO 2 with well-controlled morphologies has not been demonstrated.…”

Transferring traditional plasmonic noble metal nanomaterials from the laboratory to industrial production has remained challenging due to the high price of noble metals. The development of cost-effective non-noble-metal alternatives with outstanding plasmonic properties has therefore become essential. Herein, we report on the gram-scale production of differently shaped TiN nanoparticles with strong plasmon-enabled broadband light absorption, including differently sized TiN nanospheres, nanobipyramids, and nanorod arrays. The TiN nanospheres and nanobipyramids are further coembedded in highly porous poly(vinyl alcohol) films to function as a photothermal material for solar seawater desalination. A seawater evaporation rate of 3.8 kg m –2 h –1 is achieved, which marks the record performance among all plasmonic solar seawater desalination systems reported so far. The removal percentage of phenol reaches 98.3%, which is attributed to the joint action of the excellent photocatalytic ability and the superhydrophilicity of the porous TiN-based composite film.

“…A typical hollow TiO 2 sphere (HTS) structure was successfully synthesized using a versatile kinetics-controlled coating and carbonization method. 103 The resorcinol/formaldehyde (RF) polymer resin was prepared and used for the hard templates by the extended sol–gel process. After the removal of the template, the hollow structure was successfully fabricated which can be clearly observed in the TEM images (Fig.…”
