Production of molecular hydrogen (H 2 ) is becoming an increasingly prominent process, due to high expectations as a new green energy carrier and key reagent for many industrial processes. Herein we report the high efficiency of H 2 production via photoreforming of ethanol using a catalyst based on hierarchical carbon nanocones hybridised with an inorganic layer of nanocrystalline TiO 2 containing Pd nanoparticles. Production of molecular hydrogen (H 2 ) is becoming an increasingly prominent process, due to the high expectations as a new green energy carrier and key reagent for many industrial processes.
