CoP-Embedded Graphitic N-Doped C Nanosheets in Ohmic Contact with S-Deficient CdS Nanocrystals Triggering Efficient Visible-Light Photocatalytic H2 Evolution

“…Thus, the charge-separating capability of 70%-CdS/CoP-CN associated with its outstanding HER activity was investigated by photocurrent response, EIS, and PL tests. According to Figure a, 70%-CdS/CoP-CN exhibits a photocurrent density much higher than those of CdS and CoP-CN, implying that 70%-CdS/CoP-CN is in possession of a better capability for charge separation, presumably due to the existence of a heterojunction in the composite. , Moreover, Figure b discloses that the EIS Nyquist arc diameter of 70%-CdS/CoP-CN is dwindled by comparison to those of CdS and CoP-CN, suggesting that the former has a lowered charge-transfer resistance . The reduced charge-transfer resistance helps to accelerate the charge transmission and separation processes of 70%-CdS/CoP-CN, thus promoting the photocatalytic reaction effectively .…”

Photogenerated Defect‐Transit Dual S‐Scheme Charge Separation for Highly Efficient Hydrogen Production

“…Thus, the crafted design of heterostructured nanocomposites with efficient photoinduced charge separation would be a promising candidate way to enhance the photocatalytic activity in HER. [7] Recently, semiconductor-related nanomaterials with localized surface plasmon resonance (LSPR) effects (e.g., Cu 2−x S, Cu 2−x Se, WO 3−x , and MoO 3−x ) have attracted great interest due to the powerful and extensive near infrared (NIR) light absorption. [8] Especially, W 18 O 49 in these non-stoichiometric tungsten oxides, with far-reaching implications in terms of performance and applications, [9] due to its suitable band gap energy, abundant oxygen deficiency, adjustable electronic structure, and the presence of mixed valence W ions giving the unique photocatalytic properties.…”

Engineering dual charge transfer material modified ZnxCd1−xS towards highly effective photocatalytic pure water splitting

“…28 Nevertheless, these single-component photocatalysts exhibit inefficient photocatalytic activity due to the rapid recombination of photogenerated electron-hole pairs and insufficient surface active sites. 3,29,30 Therefore, the research on a highly efficient charge separation strategy is a key point in enhancing the photocatalytic intermediate water splitting performance of ZnCdS solid solution.…”
