1. A photocatalysis process to produce hydrogen and at least one oxygen functionalized multiwalled carbon nanotube, comprising the steps of:
applying light to saturated hydrocarbons in the presence of a metal particle supported metal oxide photocatalyst to produce the hydrogen and the at least one oxygen functionalized multiwalled carbon nanotube, wherein a light intensity is in a range of 2-200 W cm−2 and wherein a wavelength of the light is from 200 nm to 2500 nm;
separating the hydrogen from the at least one oxygen functionalized multiwalled carbon nanotube; and
collecting the separated hydrogen and the at least one oxygen functionalized multiwalled carbon nanotube.
