Journal ArticleDOI
TiO2 modification by gold (Au) for photocatalytic hydrogen (H2) production
TL;DR: In this paper, a brief description of TiO2-Au nanocomposite synthesis by different methods viz. sol-gel, photodeposition, deposition-precipitation simple reducing method and dispersion method is provided.
Journal ArticleDOI
Band alignment and charge transfer pathway in three phase anatase-rutile-brookite TiO2 nanotubes: An efficient photocatalyst for water splitting
TL;DR: In this paper, the authors reported electrochemical synthesis, phase evolution and hydrogen generation efficiency of anatase, rutile and brookite (ARB) TiO 2 nanotubes for the first time.
Journal ArticleDOI
Energy efficient reduced graphene oxide additives: Mechanism of effective lubrication and antiwear properties
TL;DR: It is demonstrated that effective lubrication is possible, if rGO is chemically linked with PEG molecules through hydrogen bonding and PEG intercalated graphene sheets provide sufficiently lower shear strength of freely suspended composite tribofilm under the contact pressure.
Journal ArticleDOI
Novel single phase vanadium dioxide nanostructured films for methane sensing near room temperature
TL;DR: In this paper, vanadium dioxide (VO2) nanostructured films are synthesized by pulsed dc-magnetron sputtering of V target followed by oxidation in O2 atmosphere at 550°C.
Journal ArticleDOI
