The present work considers the concept of enzymatic photoelectrochemical generation of hydrogen through water splitting using a Xe lamp as a source of light. A solar cell was applied to the system in order to shift the level of electrochemical energy of the system, resulting in the rate of hydrogen production at $43;{mu}mol/(cm^2{ imes}hr)$ in cathodic compartment with an anodized tubular $TiO_2$ electrode(ATTE, $5^{circ}C$/1hr in 0.5 wt% HF-$650^{circ}C$/5hr). The trend of the rate of hydrogen production, for the ATTEs with different annealing temperature from $350^{circ}C$ to $850^{circ}C$, fairly well coincided with the photoelectrical properties measured by potentiostat. The actual chemical bias through imposition of two electrolytes of different pHs between anode(13.68) and cathode(7.5) was 0.24eV.
