Efficient solar conversion of carbon dioxide and water vapor to methane and other hydrocarbons is achieved using nitrogen-doped titania nanotube arrays, with a wall thickness low enough to facilitate effective carrier transfer to the adsorbing species, surface-loaded with nanodimensional islands of cocatalysts platinum and/or copper. All experiments are conducted in outdoor sunlight at University Park, PA. Using outdoor global AM 1.5 sunlight, 100 mW/cm2, a hydrocarbon production rate of 111 ppm cm−2 h−1, or ≈160 μL/(g h), is obtained when the nanotube array samples are loaded with both Cu and Pt nanoparticles.

    This is bullshit and Peter you’re a wuss, “reading newenergyandfuel.com every day”.
    Visit abovetopsecret.com, get educated.
