dc.description.abstract | Doping engineering is of key importance for controlling the electrical, optical, and structural properties of a semiconductor. In more expanded doping systems, codoping with deep insight and understanding of interactions between impurities is necessary to make an efficient photoelectrode. Here, we show that the high formation energy of a Si-doped hematite can be decreased with the introduction of a host Ti-dopant, making easy and cost-efficient solution-based Si doping possible. The effect of the positive interaction between dopants lowers the formation energy in a standard atmosphere to the one under extreme conditions of about 10(-10) atm. By taking advantage of formation energy control, we achieved a photocurrent density of 4.3 mA cm(-2) at 1.23 V-RHE in the optimized Si:Ti codoped hematite with a cocatalyst without using any demanding experimental processes. Our study suggests a ground rule for the facile incorporation of the high-formation-energy dopant into photocatalysts, which can be readily extended to other doped systems to achieve a substantial improvement in PEC performance. | - |
