Advanced Catalysts for Photoelectrochemical Water Splitting
Abstract
Photoelectrochemical (PEC) water splitting offers a sparkling and sustainable strategy for hydrogen generation, and significant research for enhancing the conversion efficiency of electrocatalysts is underway, since a huge number of publications have been reported in this field. Hence, it is urgent to write a comprehensive and updated review in order to highlight the latest progress in the design, fabrication, and modification of electrocatalysts for high-efficiency PEC water splitting. In this review, we describe the basic mechanism of PEC water splitting utilizing electrocatalysts in detail. Further, we highlighted the recent advancements in the design, fabrication, and modification of high-efficiency electrocatalysts for energy conversion. In addition, the catalysts’ surface passivation, heterojunction constructions, defect engineering, and photovoltage and photocurrent enhancements are also highlighted.

The low electronic conductivity, wide band gap, rapid charge carrier recombination, and small accessible surface active sites of carbon nitride greatly limit its application in water splitting and photosynthesis.
“Unfortunately, the low electronic conductivity, wide band gap, rapid charge carrier recombination behavior, as well as the fairly small accessible surface active sites, have greatly limited its application in water splitting and photosynthesis [6, 7].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
