Nanoscale Assembly of BiVO4/CdS/CoOx Core–Shell Heterojunction for Enhanced Photoelectrochemical Water Splitting

“…As shown in the literature, SPECM allows to identify such local disparities [43]. This will be the focus of future works with quantitative studies using the same measurement method thoroughly explained in Figure S7.…”

“…Furthermore, the topographical map presented in Figure7bshows that thicker part of the scanned area corresponds to the highest activities measured in the photocurrent and ORR maps. This also suggests the presence of local inhomogeneities due to the local quantity of material or an incomplete surface modification from synthesis processes on the micro-or nanoscale.As shown in the literature, SPECM allows to identify such local disparities[43]. This will be the focus of future works with quantitative studies using the same measurement method thoroughly explained in FigureS7.…”

“…SPECM brings a spatially resolved study of the local properties of photoelectrocatalysts. Thus, it allows a detailed investigation and understanding of the photocatalysts and PEC mechanisms [43].…”

Monitoring Transformations of Catalytic Active States in Photocathodes Based on MoSx Layers on CuInS2 Using In Operando Raman Spectroscopy

“…However, these conditions do not always directly reflect the actual environment of the electrode in the cell, which is a solvated solid surface with liquid junction. [3] Therefore, there is an urgent requirement for developing methods that allow the electrode chemical states to be characterized and the mechanisms of reactions on the electrode surface to be tracked in operando. [4] Under (photo)electrochemical reaction conditions, Raman spectroscopy is an ideal tool for in operando characterization.…”

Solar energy and the circular economy: An introduction

“…But the exploration of the mechanistic details of the reactions taking place in reactor materials is not trivial and requires sophisticated analytical methods. Naldoni et al provide a review of the novel operando and in situ analytical methods for the study of photoelectrochemical systems in this respect [17].…”
