Enhanced Solar Water Splitting by Swift Charge Separation in Au/FeOOH Sandwiched Single Crystalline Fe${}_2$O${}_3$ Nanoflake Photoelectrodes

Lei Wang, Nhat Truong Nguyen, Yajun Zhang +2

In this work, single crystalline $\alpha$-Fe${}_2$O${}_3$ nanoflakes (NFs) are formed in a highly dense array by Au seeding of a Fe substrate by a thermal oxidation technique. The NFs are c…
