优化的FTO晶种使得能够生长高效的Ta掺杂的TiO $_2$纳米棒光阳极
Optimized FTO seeding enables the growth of high efficient Ta-doped TiO$_2$ nanorod photoanodes
摘要：
采用一种新的引晶方法在FTO衬底上水热生长了钽掺杂的金红石纳米棒。这种方法允许掺入高达4.8at%的高浓度钽作为活性掺杂，并导致光电化学水裂解速率的显著增强（在+1.5V vsRHE的电势下为1.8mA/cm 2），其对应于约1.5mA/cm 2。在AM 1.5，100 mW/cm 2模拟太阳光照射下，光电流转换效率为1%。
英文摘要：
Tantalum doped rutile nanorods were hydrothermally grown on FTO substrates using a new seeding approach. This approach allows the incorporation of high concentrations of up to 4.8 at% tantalum as active doping and results in a significant enhancement of photoelectrochemical water splitting rate (1.8 mA/cm2 at a potential of +1.5 V vs RHE) which corresponds to ca. 1% photocurrent conversion efficiency under AM 1.5, 100 mW/cm2 simulated sunlight irradiation.
