Several characterizations have been employed to reveal the nature of the modification imparted to the MWCNTs under hydrothermal processing conditions and the resulting TiO2-MWCNT conjugation through -COOH groups. Efficient charge transfer In the nanocomposite and efficient electron transport by MWCNT (significantly higher Incident-photon-to-current conversion efficiency) are suggested to be the possible reasons for the enhancement.</p>10aCarbon nanotubes10acharge transfer10aDye-sensitized solar cells10aHybrid composite10ahydrothermal1 aMuduli, Subas1 aLee, Wonjoo1 aDhas, Vivek, V.1 aMujawar, Sarfraj1 aDubey, Megha1 aVijayamohanan, K.1 aHan, Sung-Hwan1 aOgale, Satishchandra  uhttps://library.ncl.res.in/content/enhanced-conversion-efficiency-dye-sensitized-solar-cells-based-hydrothermally-synthesized-001393nas a2200241   4500008004100000022001400041245012700055210006900182260011000251300001400361490000700375520044900382100002400831700002000855700001700875700002000892700001700912700002500929700001800954700002300972700002500995856013101020       2011                        eng d  a1463-926200aFrom graphite oxide to highly water dispersible functionalized graphene by single step plant extract-induced deoxygenation0 aFrom graphite oxide to highly water dispersible functionalized g  aTHOMAS GRAHAM HOUSE, SCIENCE PARK, MILTON RD, CAMBRIDGE CB4 0WF, CAMBS, ENGLANDbROYAL SOC CHEMISTRYcJUL  a1990-19960 v133 a<p>We report a single step facile synthesis of highly water dispersible functionalized graphene nanosheets by plant extract-induced deoxygenation of graphite oxide (GO).
