| contents | Photocatalytic water splitting represents a pivotal pathway for converting solar energy into chemical energy, with the core challenge lying in the design and optimization of photocatalysts [1] . TiO2, as a quintessential photocatalytic material, undergoes significant alterations in its electronic and crystalline structures under intense light irradiation, which may directly impacts its photocatalytic efficiency [2] . To gain a profound understanding of these transformations, in situ characterization techniques such as X-ray scattering and neutron scattering have emerged as crucial tools. This paper, from a combined perspective of theoretical computation and experimental characterization, explores the differential capabilities of X-ray scattering and neutron scattering in characterizing the pair distribution function (PDF) of materials during photocatalytic water splitting. Furthermore, through simulation calculations, it aims to unveil the changes in the electronic and crystalline structures under intense light irradiation. This initial draft of the paper is subject to subsequent revisions. |
