We discussed here on a novel approach to reduce CO2 back to liquid fuels by using an electrochemical device working in gas phase. Operating under solvent-less conditions is very attractive and has many advantages with respect to a slurry reactor work

We report here on the sustainable production of hydrogen by the use of nano-ordered TiO2 arrays doped with gold nanoparticles (Au NPs). The presence of a nano-architecture in TiO2 substrate may strongly improve the ability to disperse the Au NPs on i
