Climate change, driven by human-induced greenhouse gas emissions, necessitates sustainable energy solutions. Hydrogen energy is a promising alternative due to its high efficiency and zero emissions.AASA synthesis had been used appropriate Copper loading in a Titanium precursor.Observe the effect of different copper doping ratios in titanium dioxide on photocatalytic efficiency and hydrogen production efficiency.The solution homogeneously mixed ethanol, acetic acid, Tetrabutyl Titanate (Ti(OBu)4), hydrochloride acid, and copper nitrate than directly spray by air compressor, after that collected and calcined at 450℃ with air.Photocatalytic tests, 50mg of Copper Titanium material with 50% Ethanol under 450W of 365nm UV at room temperature. H2 was measured by GC/TCD--Mass after 20 hours irradiation, carry gas is Ar.Material properties analysis demonstrated AASA process to prepare Copper oxide Titanium enhancement the SBET (155 m2/g).The production of hydrogen decreasing fellow Cu/Ti ratio increasing. In our case, 0.6wt% of Copper oxide Titanium exhibit the maxima reforming conversion also reduce initial transformation time.
