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.
