Spherical shell CdS@NiO Z-scheme composites for solar-driven overall water splitting and carbon dioxide reduction

Creation and Plasmon-Assisted Photosensitization of Annealed Z-Schemes for Sunlight-Only Water Splitting

“…We recalculated our results for STH and obtained a value of 0.64% (and the corresponding high amount of produced hydrogen�Table 1), which significantly exceeds some previously published ones. [78][79][80][81][82]87,89 Our STH values (or the amounts of hydrogen produced) are somewhat lower than the best ones, which, unlike us, were obtained with sacrificial agents. 70,83,84,88,90 Finally, the quantum efficiency (QE) of hydrogen production was calculated for the more interesting case of the utilization of double wavelength triggering of WC-700 flakes deposited on the plasmon-active grating surface.…”

“…In particular, most of the published works utilize the STH (solar-to-hydrogen) value as a quantitative parameter of light-induced water splitting efficiency. We recalculated our results for STH and obtained a value of 0.64% (and the corresponding high amount of produced hydrogenTable ), which significantly exceeds some previously published ones. − ,, Our STH values (or the amounts of hydrogen produced) are somewhat lower than the best ones, which, unlike us, were obtained with sacrificial agents. ,,,, Finally, the quantum efficiency (QE) of hydrogen production was calculated for the more interesting case of the utilization of double wavelength triggering of WC-700 flakes deposited on the plasmon-active grating surface. Using the known light irradiance on the sample surface and the amount of hydrogen produced, we obtain QE = 79.33%, which is close to those recently reported in recent top papers. − Therefore, we can conclude that from the point of effectiveness and efficiency, the proposed approach is fully competitive, especially for direct water splitting without the addition of sacrificial agents, commonly used and consumed during water photolysis.…”

“…We also compared our approach with those of other groups working on artificial leaf (or Z-scheme-based water splitting) research (see Table ,− ). As can be seen, our results are comparable with the best results of other authors.…”

Photodeposited nickel-loaded ZnCdS nanoparticles for hydrogen production from photocatalytic water splitting

“…Noble metals play an important role as a co-catalyst in enhancing the photocatalytic performance of sulfide semiconductors. 13 However, the high cost of noble metals and the shortage of their resources limit their large-scale application. Currently, non-noble metals, such as Ni, 14 Co 15 and Bi, 16 have been demonstrated by researchers to improve the photocatalytic performance of sulfide semiconductors.…”

Photocatalytic co-production of hydrogen gas and N-benzylidenebenzylamine over high-quality 2D layered In4/3P2Se6 nanosheets

“…The photocatalytic synthesis of high valued chemicals is expected to be a promising approach to alleviate the global energy crisis and resource shortage. [1][2][3][4] The co-production of hydrogen gas and organic transformation represent a promising avenue to efficiently utilize solar light for chemicals and clean fuels. In particular, N-benzylidenebenzylamine (N-BD) is a highly valuable chemical and crucial for manufacturing pharmaceuticals, pesticides, biologically active compounds, fragrance and dyes.…”
