Abstract
A multiwalled carbon nanotube includes at least 2 carbon nanotube walls. The multiwalled carbon nanotube have an outer surface and at least a portion of an oxygen functional group is attached to the outer surface thereof. Up to 5 atomic percent of the multiwalled carbon nanotube surface is an oxygen functional group. The surface atomic ratio of carbon to oxygen is between 17:1 and 19:1. A photocatalysis process to produce hydrogen and at least one solid carbon nanostructure includes the steps of: applying light to saturated hydrocarbons in the presence of a metal particle supported metal oxide photocatalyst to produce at least hydrogen gas and at least one solid carbon nanostructure; separating the hydrogen from at least one solid carbon nanostructure; and collecting the separated hydrogen and the at least one solid carbon nanostructure.
