The addition of Re to Ni on TiO2 yields efficient catalysts for the hydrogenation of acids and esters to alcohols under mild conditions. Rhenium promotes the formation of atomically dispersed and sub-nanometre-sized bimetallic species interacting strongly with the oxide support.

For a full estimation of the risk related with the presence of engineered nanoparticles (ENPs) in the environment, the use of the current ecotoxicological methods may prove insufficient. In the study presented herein, various methods of assessment of ecotoxicity were applied to compare the phytotoxicity of three ENPs: nano-ZnO, nano-TiO2 and nano-Ni. The toxicity was assayed both for aqueous so...

The huge scale of plastic waste generation and its environmental consequences drive the demands for catalytic upcycling processes. Here, we report efficient polypropylene (PP) hydro-conversion over Ru Ni supported on a sol-gel anatase TiO2 (TiO2-A-SG). A small number Brønsted acid sites TiO2-A-SG enables hydrocracking, improving efficiency, steering selectivity towards high-valued C4-20, allowi...

Integrated CO2 capture and utilisation (ICCU) is a promising strategy for restricting carbon emissions achieving neutrality. Bifunctional combined materials (BCMs), containing adsorbents active catalysts, are widely applied in this process. Producing syngas via reverse water–gas shift reaction (RWGS) integrating with Fischer-Tropsch (F-T) synthesis an attractive valuable route. This work invest...

In the current work, we report a series of bifacial dye-sensitized solar cells (DSSCs) that provide power conversion efficiencies of more than 10% from bifacial irradiation. The device comprises an N719-sensitized TiO2 anode, a transparent nickel selenide (Ni-Se) alloy counter electrode (CE), and liquid electrolyte containing I(-)/I3(-) redox couples. Because of the high optical transparency, e...

The morphology and composition of Ni–Sn Ni–Sn–TiO2 coatings have been studied by scanning electron microscopy energy-dispersive X-ray analysis. electrochemical behavior the obtained in a 3% NaCl solution has examined. influence inclusion titania coating on mechanical antibacterial properties revealed. Dependences incubation time exposure to UV radiation concentration living bacteria cells surfa...

This investigation proposes the use of sol-enhanced electrodeposition to create a range Co−Ni−TiO2 films. The addition TiO2 sol controls nucleation process and properties composite films by generating nanoparticles in situ process. transmission electron microscopy (TEM) zeta potential analyses revealed relatively homogenous distribution with particle size below 100 nm for produced.
