AB  - The concept of photocatalytic CO2 and H2O conversion to solar fuels and value-added products provides simultaneous solution for increased energy demands and environmental problems. However, the lack of efficient photocatalysts restrains the large-scale development of photocatalytic technology. In the present study, noble (Pt and Au) and transition metal (Ni) doped nanoflakes assembled on TiO2@carbon microrods with high surface area and rutile crystal structure is prepared via fast, versatile solvothermal method. The photocatalytic performance of the prepared nanocomposites was evaluated in two photocatalytic systems: CO2 reduction and hydrogen production via photoreforming. Pt-doped catalyst showed enhanced hydrogen production efficiency and increased CH4 selectivity, while Ni-doped catalyst exhibited remarkable CO2 reduction activity with higher selectivity towards CO. The mechanism of Pt-promoted CH4 formation and Ni- and Au-promoted CO formation was thoroughly discussed regarding kinetic and thermodynamic parameters.

AB  - Heterogeneous photocatalytic oxidation technologies, based on the free-radical reaction initiated by a light irradiation of photocatalyst surface, are promising methods for water and air purification, being one of overwhelming concerns in the scientific community regarding the challenges of exponential environmental pollution increase. Mixed oxides derived from ZnAI containing layered double hydroxides (LDH) without or with doping agents (Fe, Sn and Ti) have been recently implemented as efficient and environmental-friendly materials in the photodegradation process of organic compounds in aqueous media. Considering both, the progress in the synthesis of photoactive LDH and evident drawbacks of classical methods, the study is focused on the development of an innovative, simple and cost effective synthesis method of TiO2 containing ZnAI LDH based photocatalysts with improved overall photo-catalytic and antibacterial performances in water purification processes. In order to elucidate the relationship between the functional material properties developed in TiO2 impregnation process and photo induced catalytic and antibacterial activity, comprehensive studies encompassed structural (XRD), textural (low temperature nitrogen adsorption), electronic properties (diffuse reflectance spectroscopy) and morphology (SEM) of developed TiO2-ZnAl LDH based materials, as well as the XPS study of the most active photocatalysts, in correlation to photo-induced catalytic activity (Methylene Blue degradation) and antibacterial activity (Gram-negative E. coli and Gram-positive bacterium S. aureus as indicator strains). The results confirmed that innovative impregnation method using base solution enables favorable interactions among active phases promoting the synergetic effect and complex interactions between the TiO2 (3 mas%) and ZnAl mixed oxides, enhancing photocatalytic activity to the level almost equal to TiO2, simultaneously improving the overall antibacterial performance.
