Watch this video from MIT researchers Yogesh Surendranath, Thomas Teets, and Dr. Elizabeth R. Young to see how you can
perform water splitting experiments with just a few simple materials.
At an applied potential of 0.3 volt, chemically modified n - type TiO2
performs water splitting with a total conversion efficiency of 11 % and a maximum photoconversion efficiency of 8.35 % when illuminated at 40 milliwatts per square centimeter.

Anthony Griffin, a retired Royal Navy admiral, described patented apparatus developed in the US to
perform the supposedly impossible task of
splitting water with a tiny current into hydrogen and oxygen, which can be burnt.
Our lab at MIT invented a process that
splits water and

(From left to right): Chengxiang Xiang and Erik Verlage assemble a monolithically integrated III - V device, protected by a TiO2 stabilization layer, which
performs unassisted solar
water splitting with collection of hydrogen fuel and oxygen.
Current model CO2 converters, known as electrocatalysts, don't produce carbon monoxide because their inherent chemistry forces them to
perform a different operation, known as the hydrogen evolution reaction (HER) or «
water -
splitting».

perform splitting outweigh the energy created from hydrogen when the Hydrogen is
split from the
water molecule H2O.
