Abstract
Titanium dioxide (TiO2) has been extensively studied for solar-light-driven water oxidation as photoanode in photoelectrochemical (PEC), but enabled to hold promise for low cost and sustainable fuel. However, the performance of TiO2 for scalable artificial photosynthesis has remained critical obstacle for practical application. Herein, we report the influence of aqueous solution of NaPi and KPi buffer and varying pH from 9.0 to 11.5, with Partially Crystalline Nitrogen-doped Titanium Dioxide (PCNDTO) for solar-derived PEC syngas production and analyzed for all variables. A maximum photocurrent of 4.35 mAcm−2 at 1.23 V/RHE with 9.7–10.9 ml h−1 cm−1 hydrogen production rate was obtained at pH 10.5 in NaPi buffer.
