CdS Nanoparticle-Modified α-Fe2O3/TiO2 Nanorod Array Photoanode for Efficient Photoelectrochemical Water Oxidation
In this work, we demonstrate a facile successive ionic layer adsorption and reaction process accompanied by hydrothermal method to synthesize CdS nanoparticle-modified α-Fe2O3/TiO2 nanorod array for efficient photoelectrochemical (PEC) water oxidation. By integrating CdS/α-Fe2O3/TiO2 ternary system, light absorption ability of the photoanode can be effectively improved with an obviously broaden...
متن کاملAu@CdS Core–Shell Nanoparticles‐Modified ZnO Nanowires Photoanode for Efficient Photoelectrochemical Water Splitting
Hydrogen production from water splitting using solar energy based on photoelectrochemical (PEC) cells has attracted increasing attention because it leaves less of a carbon footprint and has economic superiority of solar and hydrogen energy. Oxide semiconductors such as ZnO possessing high stability against photocorrosion in hole scavenger systems have been widely used to build photoanodes of PE...
متن کاملWater Splitting: Achieving Highly Efficient Photoelectrochemical Water Oxidation with a TiCl4 Treated 3D Antimony‐Doped SnO2 Macropore/Branched α‐Fe2O3 Nanorod Heterojunction Photoanode (Adv. Sci. 7/2015)
In article number 1500049, Dai-Bin Kuang and co-workers demonstrate a novel macroporous antimony-doped SnO 2 as dedicated charge collector with high surface area and optical enhancement to load hematite nanorods for highly efficient water splitting. With post treatments, the composite photoanode achieves an impressive photocurrent density under sun illumination.
متن کاملAchieving Highly Efficient Photoelectrochemical Water Oxidation with a TiCl4 Treated 3D Antimony‐Doped SnO2 Macropore/Branched α‐Fe2O3 Nanorod Heterojunction Photoanode
Utilizing photoelectrochemical (PEC) cells to directly collecting solar energy into chemical fuels (e.g., H2 via water splitting) is a promising way to tackle the energy challenge. α-Fe2O3 has emerged as a desirable photoanode material in a PEC cell due to its wide spectrum absorption range, chemical stability, and earth abundant component. However, the short excited state lifetime, poor minori...
متن کاملHigh-performance n-Si/α-Fe2O3 core/shell nanowire array photoanode towards photoelectrochemical water splitting.
Many narrow band-gap semiconductors cannot fulfil the energetic requirements for water splitting, thus the assistance of large external voltages to complete the water decomposition reaction is required. Through thermal decomposition of Fe(NO3)3 on n-Si nanowires prepared by the chemical etching method, we fabricated a high-performance n-Si/α-Fe2O3 core/shell nanowire array photoanode that exhib...
