Graphitic Layered Structures Enhancing TiNT Catalyst Photo-Electrochemical Behaviour

The increasing knowledge in nanoscience and materials technology promoted the development of advanced with enhanced unusual properties suitable for sustainable applications ranging from energy to environmental purposes. Here are presented some results our current investigations on composite semiconducting materials. investigated composites have been prepared different nitrogen precursors thin films TiO2 nanotubes. synergy between hetero-structures based graphitic-C3N4 titania nanotubes obtained by anodisation was studied. characterised several complementary techniques evidence relation photo-behaviour composition samples. This study allows new insights into nature specific due this among two compounds. g-C3N4/TiNT heterojunctions showed photo-electrochemical observed photocurrent measurements. as-prepared as cathode electrocatalytic reduction oxalic acid (OX), evidencing capability tuning reaction toward glycolic respect pristine TiNT array. Faradic efficiency (FE) follows trend: TiNT-U6 > TiNT-M6 TiNT-MU18. shows best performances (FEGC = 63.7%; FEGO 15.5%; OX conversion 61. 4%) after 2 h reaction. improved make these H2 production, solar-light-driven water splitting, CO2 applications.
