“…Here the focus has been on TiO 2 coated multiwalled carbon nanotubes [88][89][90][91]. Many authors (e.g., [1][2][3]8,9,15,16,[24][25][26][27]29,[35][36][37][38][40][41][42][43][53][54][55][92][93][94][95][96][97][98]) have studied the immobilization of TiO 2 nanoparticles on much larger supports, often in the form of coatings or thin films, by processes such as metal oxide chemical vapour deposition (CVD) and infiltration, liquid phase deposition, barriertorch discharge-, ion beam enhanced-, arc-and pulsed laser deposition, sol-gel methods, including dip coating, a variety of technologies involving spraying and sputtering and electrophoretic deposition.…”
