A generalized solid-state nudged elastic band method.
Daniel Sheppard,Penghao Xiao,William D. Chemelewski,William D. Chemelewski,Duane D. Johnson,Duane D. Johnson,Duane D. Johnson,Graeme Henkelman +7 more
TL;DR: A generalized solid-state nudged elastic band (G-SSNEB) method is presented for determining reaction pathways of solid-solid transformations involving both atomic and unit-cell degrees of freedom and it is demonstrated that the method is robust for mechanisms dominated either by atomic motion or by unit- cell deformation.
Journal ArticleDOI
Amorphous FeOOH Oxygen Evolution Reaction Catalyst for Photoelectrochemical Water Splitting
TL;DR: An amorphous FeOOH (a-FeOOH) phase that has not previously been studied as an OER catalyst is synthesized and shown activity comparable to that of another OER cocatalyst, Co-borate (Co-Bi), in 1 M Na2CO3.
Journal ArticleDOI
Unravelling Small-Polaron Transport in Metal Oxide Photoelectrodes
TL;DR: Analysis of recent transport studies of two prototypical oxide photoanodes shows that conduction in both materials is well-described by the adiabatic small-polaron model, with electron drift mobility values on the order of 10(-4) and 10(-2) cm(2) V(-1) s(-1), respectively.
Journal ArticleDOI
Synthesis of BiVO4 nanoflake array films for photoelectrochemical water oxidation
Huichao He,Huichao He,Sean P. Berglund,Alexander J. E. Rettie,William D. Chemelewski,Peng Xiao,Yunhuai Zhang,C. Buddie Mullins +7 more
TL;DR: In this paper, a simple drop-casting method was proposed to synthesize un-doped and doped bismuth vanadate (BiVO4) nanoflake array films.
Journal ArticleDOI
Nanostructured Bi2S3/WO3 heterojunction films exhibiting enhanced photoelectrochemical performance
Huichao He,Huichao He,Sean P. Berglund,Peng Xiao,William D. Chemelewski,Yunhuai Zhang,C. Buddie Mullins +6 more
TL;DR: In this paper, a Bi2S3/WO3 heterojunction film was designed by coupling WO3 films with varying amounts of urchin-like Bi 2S3 nanospheres.
