“…The results presented so far reveal that the modification of TiO 2 with the as-generated catalyst based on molybdenum sulfide enhances the electrode properties for the HER greatly. Some authors have reported the possibility of TiO 2 sensitization to visible light by MoS 2 nanoparticles, [30] and even MoS 2 has been proposed as a photoanode material. [31] If we take into account the location of the conduction band of MoS 2 , it seems necessary to have small nanocrystals, which exhibit quantum confinement effects, to observe TiO 2 sensitization to visible light.…”

“…Even under concentrated illumination, current densities reached only a few μA/cm 2 , 2–3 orders of magnitude lower than what we observed on bulk MoS 2 samples. Earlier work by Kiesewetter et al investigated the use of small MoS 2 microcrystals as the absorber in a dye-sensitized solar cell . Unfortunately, few crystallites were found to be active, and overall photoactivity remained low.…”

Bridging the Gap Between Bulk and Nanostructured Photoelectrodes: The Impact of Surface States on the Electrocatalytic and Photoelectrochemical Properties of MoS₂

Molybdenite (MoS 2 ) is a material that has been previously studied for its photoelectrochemical properties in bulk form and, more recently, for its electrocatalytic hydrogen evolution properties in various nanostructured forms. Herein, we aim to address the properties of bulk and nanostructured MoS 2 in order to assess the future potential of harnessing nanostructured MoS 2 as a more efficient photocathode for photoelectrochemical hydrogen production. Using an in-situ method to progressively create defects at the surface of bulk MoS 2 , we show that losses due to recombination of photogenerated charge carriers at surface states occur concurrently with an enhancement in catalytic activity for hydrogen evolution. We further explore how these surface defects affect the measured flat-band potential, and we discuss the consequences of the distinct electronic properties of bulk versus nanostructured MoS 2 . Our results for MoS 2 show that differences in morphological length scales (bulk vs nanoscale) give rise to unique surface properties that can greatly impact material performance and that represent key differences that researchers can leverage in order to develop more efficient nanoscaled photoelectrodes.

“…19) and WSe 2 (ref. 20) particles have also shown to be effective photosensitizers to TiO 2 surfaces in analogy to quantum dot sensitization. 21 Despite the promising photocatalytic and PEC properties, scalability remains a common challenge for TMD-based photoanodes.…”
